We want you to take a bird’s eye view of restoration with our wildlife webcams. In 2006, NOAA’s Montrose Settlements Restoration Program, established to make up for a toxic DDT and PCB legacy in southern California, installed a live webcam with a close-up view of the first Bald Eagle nest to hatch a chick naturally on California’s Santa Cruz Island in over 50 years. Thousands watched as the eagle parents tended to their chick, affectionately named “Princess Cruz” by webcam watchers. Today, there are a total of five webcams on other nests around the California Channel Islands, highlighting the success of our Bald Eagle Restoration Program.
We also wanted to connect the public to the underwater world of wetlands with an underwater fish webcam. In 2010, our program installed a live webcam in Huntington Beach wetlands, where we completed one of our fish habitat restoration projects. This underwater camera demonstrates the importance of wetlands as a fish nursery and feeding area.
Watch Bald Eagles Live

What is cute and cuddly and has wings? You guessed it … a Bald Eagle chick! What is even better is that you can watch these adorable birds on live webcams that are placed near Bald Eagle nests located on Catalina and Santa Cruz Islands in the California Channel Islands right now. Viewers can watch daily as both male and female adults attend to their chicks by feeding them and keeping them warm. One of the most popular nests to watch is the West End nest on Catalina Island that has triplets for the third year in a row.
For eagle enthusiasts, there is a Channel Islands Eaglecam discussion forum where you can post or read daily nest observations, chat with other enthusiasts, or read updates from the Bald Eagle restoration team. With over 1 million hits each year, the Bald Eagle webcams have captivated audiences all over the world from January to June as these regal birds raise their young.
Diving with the Fish
If you are more interested in what lurks beneath the ocean then you should check out the live fish webcam that is broadcast from Talbert Marsh in the Huntington Beach wetlands. Since the fish webcam has been live, we have observed over 20 species of fish, diving seabirds, an octopus, nudibranchs (colorful sea slugs), and numerous other cool invertebrates. We have also seen fish spawning events, territorial displays of fish, and even sharks.
If you want to let us know what you have seen on our webcam, you can fill out our online fish webcam observation sheet. In case our solar-powered camera is down, you can check out this 10 minute clip recorded from the webcam for a snapshot of what you might normally see. The eelgrass swaying side to side is mesmerizing and you can always catch a glimpse of a fish when you log onto the fish webcam. Test your fish identification skills now!

Examining the Japanese skiff that washed up near Crescent City, Calif., on April 7, 2013. This is the first verified item from the Japan tsunami to appear in California. (Redwood Coast Tsunami Working Group)
The Consulate General of Japan in San Francisco has confirmed to NOAA that a 20-foot-long skiff found near Crescent City, Calif., is the first verified piece of Japan tsunami debris to turn up in California. Crescent City, a coastal town surrounded by redwoods, is only a twenty-mile drive from Oregon down the iconic, coastal Highway 101.
Once the skiff was found, the U.S. Coast Guard and the local sheriff’s office worked quickly to remove it from the shoreline. Help translating the Japanese writing on it came from further down the coast, from staff at California’s Humboldt State University. They traced the skiff to Takata High School, located in Japan’s Iwate Prefecture, an area devastated by the March 2011 earthquake and tsunami. A teacher from the school reportedly identified the vessel as belonging to them, which the Japanese Consulate has now confirmed.

To date, 26 other marine debris items with a confirmed connection to the 2011 tsunami have washed up in Oregon, Washington, Hawaii, Alaska, and Canada’s British Columbia.
And like so many of them, the small, flat-bottomed boat that washed up in California was thick with gooseneck barnacles, a common and widespread filter feeder that attaches itself to floating objects in the open ocean. While unusual-looking, these barnacles are not invasive and have a fascinating historical myth purporting that a type of goose developed from gooseneck barnacles because they had similar colors and shapes (a typical-if-faulty basis for classifying life in earlier eras).
However, the influx of sea creatures aboard tsunami marine debris also brings the concern that aquatic species hitching a ride to North America may make themselves at home, possibly to the detriment of marine life and commerce communities here in the United States.
A submerged compartment in the back of the Japanese boat that washed up in Long Beach, Wash., provided a refuge for five striped beakfish. (Washington Department of Fish and Wildlife/Allen Pleus)
This issue was highlighted in the unusual case of another small Japanese boat lost in the 2011 tsunami. The Sai-shou-maru came ashore near Long Beach, Wash., on March 22, 2013, but the inside of it looked like a miniature aquarium. Five live fish were swimming about in a submerged compartment at the back of the boat. They were striped beakfish, a species native to coral reefs mainly in Japanese waters, sometimes found in Hawaii, but certainly not in the cold waters of the Pacific Northwest coast.
According to the Washington State Department of Ecology website, “Besides the five striped beakfish found in the open well of the boat when it washed ashore, the Washington Department of Fish and Wildlife estimates 30 to 50 species of plants and animals were also on the Sai-shou-maru – including potential invasive species. State officials quickly removed the Sai-shou-maru from the beach and collected samples of potential invasive species including the fish, algae, anemones, crabs, marine worms and shellfish.”
However, most of the species arriving on marine debris are not invasive—even if they are hitchhikers.

In the early 1970s, toxic compounds known as polychlorinated biphenyls, or PCBs, were discovered in the water, fish, and sediment of the Hudson River below General Electric Company’s plants at Hudson Falls and Fort Edward in New York.
Those PCBs have contaminated the surface water, groundwater, sediments, and floodplains of the Hudson River. We find that living resources at every level of the Hudson River’s food chains are contaminated with PCBs. We believe that serious adverse effects are likely to be occurring to wildlife exposed to this PCB contamination in the Hudson River.
A whole team of people are using their individual and collective expertise to address the problem of PCB contamination in the Hudson River and its effect on wildlife. My favorite part of this job is the teamwork among all the people working on this issue, and the interactions with our experts and the public.
We know that PCBs can cause serious harm to wildlife and other natural resources. Although a cleanup funded by GE is underway for certain sections of the Hudson River, the dredging GE is doing will leave some areas still contaminated with PCBs.
The dredging also cannot compensate for past effects of this PCB contamination on the Hudson River’s natural resources. For example, dredging will not make up for all the years that public use of the Hudson River fishery has been impaired by fish consumption advisories. Dredging will not return that lost use to the public.
In our planning to determine the effects of PCBs on wildlife, we identified mink health as one area to investigate. Mink are vulnerable to the effects of PCBs. Hudson River mink eat PCB-contaminated fish and other small creatures, and they ingest contaminated water, soil, and sediments as they look for food and build their dens. This led us to suspect that Hudson River mink might be harmed by PCBs in their environment.
The Sawmill Dam before NOAA helped install “fishways,” which allow fish to pass more easily over dams, on the Acushnet River in Massachusetts. (NOAA/Steve Block)
A version of this story first appeared on the NOAA Restoration Center website on April 8, 2013.
In 2007, as part of a habitat restoration project, NOAA helped to install stone “fishways” at two dams on the Acushnet River in Massachusetts. These fishways, designed to more closely resemble conditions found in nature, are located in the river channel and allow migrating fish to gradually gain enough elevation to successfully pass over the dams.
After 2007, when NOAA helped improve fish passage over two dams on the Acushnet River in Massachusetts, herring numbers passing through the river increased dramatically. Here, you can see the completed fishway on the Sawmill Dam. (NOAA/Steve Block)
Migrating fish, including river herring and American eels, now have much better access to habitat all along the Acushnet River, which runs 8.5 miles from the spawning areas of the New Bedford Reservoir into New Bedford Harbor and empties into Buzzards Bay. This means more opportunities for herring to grow, thrive, and spawn.
Herring are caught commercially and are also important prey fish for other commercial and recreational fish species, such as cod. But, due to very low numbers, there is currently a moratorium on the take of river herring from Massachusetts waters.
Between the 1940s and the 1970s, electrical parts manufacturers discharged wastes containing polychlorinated biphenyls (PCBs) and toxic metals into New Bedford Harbor, resulting in high levels of contamination. NOAA, through the Damage Assessment Remediation and Restoration Program (DARRP), worked with the Commonwealth of Massachusetts and the Department of Interior to fund the design and construction of these fishways. They are part of a restoration plan developed in response to decades of industrial pollution in New Bedford Harbor, a major commercial fishing port and industrial center in southeastern Massachusetts. According to NOAA, part of this site held the “highest concentrations of PCBs ever documented in a marine environment.”
So far, 34 projects—including these fishways—have been completed to restore natural resources that were injured or lost due to the contamination. Read more on the case and get the latest updates on restoration.
This spring, scientists are hoping to see even bigger runs of herring on the Acushnet. Want to see them in person? The third and fourth weeks of April should be peak migration time for these fish—check out this viewing guide for more information.
This is a post by Ian Zelo, NOAA Oil Spill Coordinator for the Office of Response and Restoration.
In the wake of the 2010 oil spill on Adak Island, a field team member from the Alaska Department of Fish and Game breaks the ice to prepare a stream for sampling, in this case, for electrofishing. Field teams also were setting small fish traps, which do not require breaking up the ice like this. (NOAA)
In the center of Alaska’s rugged Aleutian Islands is the sparsely populated Adak Island. It was here—in the middle of winter on January 11, 2010—that workers at the Adak Petroleum Bulk Fuel facility were filling an underground tank with oil from the supply tanker Al Amerat. But as the tanker satmoored at the dock, its oil began overfilling the 4.8 million gallon underground tank. Up to 142,800 gallons of #2 diesel flowed out of the tank and eventually into the nearby salmon stream, Helmet Creek.
January 12, 2010 — Looking out on spilled oil and containment boom from the Adak Small Boat Harbor into Sweeper Cove and the fuel pier. (U.S. Fish and Wildlife Service/Lisa Stitler)
Just over a mile after the creek passes the oil storage facility, it enters the Adak Small Boat Harbor, which is open to Sweeper Cove’s marine waters. Helmet Creek is equipped with gates that can partially close off the flow of the stream. That feature played to the response’s favor because spill response personnel were able to use these gates, along with boom and absorbent materials, to contain most of the oil spill in the stream.
Only a small percentage of the oil reached the boat harbor and Sweeper Cove. However, Alaska, NOAA, and the U.S. Fish and Wildlife Service, as natural resource trustees, were concerned about injury to both the stream and marine habitats and began a Natural Resource Damage Assessment (NRDA) to investigate potential environmental impacts.
Mission: Nearly Impossible
I got involved the next day, January 12, leading the NOAA team for this injury assessment. While the trustees were coordinating closely with the response, it was clear that we would need to send environmental assessment teams to the island to document the spill and its impacts on local habitats. However, there are only two flights to Adak each week. We knew the next flight to the island was on January 14 and we needed to be on it. This meant we had only two days to plan our initial assessment, recruit a field team to take samples, assemble the equipment, and finalize a field sampling protocol.
My role was to coordinate partners and tasks across two federal and four state agencies. On such a short time frame, we could not afford to work using the logical path we usually take: plan, recruit, gear up, and go. We had to scramble and do it all at once.
On the evening of January 13, our assembled field staff had flown to Anchorage, Alaska, with their field gear and were staged there for the 2:00 p.m. flight the next day. A local laboratory would assemble our sampling equipment and have it ready to pick up the following morning. We had a draft sampling protocol that would be finalized while the team was flying so they could be briefed on the details of their mission when they arrived. Things looked good.
At 6:30 a.m. on January 14, I got a call from one of our field staff. She had a personal emergency and had to pull out of the mission. Suddenly, things did not look good. To work safely and to accomplish our sampling goals, we needed four people on the team. I now had 8 hours to find another qualified person or we had to cancel. Working with our state partners, I identified and spoke to an Anchorage-based consulting firm by 8:30 a.m. We identified a potential replacement and called him on his drive into the office. By 9:00 he was on his way back home to get ready. With a little over an hour before the flight took off, we were able to get a contract in place to hire the consulting firm and buy his plane ticket. Once again, the mission was a go.

Over the next five weeks, we sent three field teams to Adak to assess injury caused by the oil spill. I was on the second mission. During the assessment we fished both Helmet Creek and similar streams (for comparison) to document the fish communities. One of the methods we used is known as “electrofishing.” A common research technique, it involves sticking an electrified wand in the water to temporarily shock and disable nearby fish and allow us to catch them. We counted and collected fish for contaminant and developmental analysis. Mussels were collected from sites in and around Sweeper Cover and Finger Bay (a nearby bay farther than we thought the oil might travel, again, for comparison). Trustees also collected dozens of water and sediment samples and surveyed birds.
During this assessment, we had to deal with a few unusual challenges. We had to operate at night in order to work at low tide. We were excluded from Helmet Creek for half of the second assessment because the responders discovered unexploded ordnance (potentially explosive weapons), which had to be removed before we could continue. We worked in streams that were partially or fully covered in ice, and on the final mission our assessment was interrupted by a blizzard. Our teams had to recover fish traps from under several feet of snow.
Ready for Restoration
In the summer of 2011, the trustees worked cooperatively with Adak Petroleum Bulk Fuel facility, the responsible party, on scoping restoration options. NOAA and the other trustee partners are now nearing a cooperative settlement with the fuel facility. We’ve reviewed possible restoration projects that could compensate the public for the injuries caused by the spill and have drafted a Damage Assessment and Restoration Plan [PDF] that is available for public comment.

In the plan, we present our preferred restoration alternative, which includes a suite of projects to improve the overall quality of Helmet Creek. Restoration is targeted at pink salmon but also will benefit the entire stream corridor. The proposed work includes restoring access to the creek for fish, removing barrels and other debris, and increasing water flow by plugging a culvert system that is drawing water from the stream. Our goal is to perform this restoration in the summer of 2013.

Some of the older nuclear waste storage tanks at Hanford in southeast Washington. (U.S. Department of Energy)
This past February, the U.S. Department of Energy confirmed that six additional nuclear waste storage tanks are leaking at the Hanford Nuclear Reservation in southeast Washington. This revelation has drawn attention once again to the ongoing challenges of assessing, cleaning up, and restoring the environment around a massive nuclear waste site.
To understand how these six aging nuclear waste tanks might affect salmon, the sagebrush-filled desert ecosystem, and nearby Columbia River, it helps to understand more about Hanford’s history. In 1943, the Hanford Site was developed by the U.S. Government for the production of plutonium as part of the Manhattan Project that developed atomic bombs during World War II. The site continued to produce plutonium as well as nuclear energy until the last reactor stopped operating in 1987. The weapons production and nuclear energy operations at Hanford left dangerous and environmentally harmful solid and liquid waste, creating one of the largest and most complex cleanup projects in the U.S. That effort has been in progress since 1989.
Hanford’s 177 total storage tanks, some of which date from the 1940s, hold more than 50 million gallons of radioactive waste. These six leaking tanks are among 149 older “single-shell” tanks, which only have one liner. (Tanks constructed more recently feature “double-shells.”) However, these older tanks were designed for a lifespan of only about 20 years. According to Washington Governor Jay Inslee, “This certainly raises serious questions about the integrity of all 149 single-shell tanks with radioactive liquid and sludge at Hanford.”

While tanks at the site have leaked in the past, news of these recently discovered leaks again raises concerns about the condition of the tanks and underscores the ongoing complexities of this assessment and cleanup.
The six leaking tanks pose no immediate threat to natural resources because they are located 200–300 feet above the groundwater table. The State of Washington indicates that there is no immediate or near-term health risk as the leaking tanks are located more than five miles from the Columbia River. In addition, measures are being taken to prevent contamination currently in the soil from entering the river.
While this latest discovery affects the ongoing cleanup, it does not change the focus of the Hanford Natural Resource Damage Assessment because the Hanford Natural Resource Trustee Council is already evaluating harm from contamination flowing into the Columbia River, which borders the site and is home to Chinook salmon and sturgeon. The council includes representatives from NOAA, three tribal organizations, the States of Washington and Oregon, and two other federal agencies. It is tasked with characterizing the cumulative impacts from decades of releases and contamination to the fish, wildlife, and the habitats they rely upon, and determining the cumulative restoration needed to replace, restore, and offset the total decades of damage.
Discovery of the additional leaking tanks illustrates the challenge of that task: to be able to measure the harm over time, even as new sources of contamination are discovered and await cleanup. Each source can add to the cumulative impact and ultimately to the amount of restoration that will eventually be needed to offset damages.
For more information about the work of the Hanford Natural Resource Trustee Council, view the Hanford Natural Resource Damage Assessment Injury Assessment Plan, which describes how the council will characterize and quantify the past, ongoing, and future environmental impacts.
For decades, two Alcoa alumininum facilities discharged toxic PCBs into the St. Lawrence River, its tributaries the Grasse and Raquette Rivers, and the surrounding area in Massena, N.Y. Alcoa and Reynolds are paying $19.4 million to settle the resulting damages to natural resources. (NOAA)
In the northern reaches of upstate New York, just across and upriver from Canada, two factories chug along. Both now owned by aluminum manufacturer Alcoa, these factories have been producing aluminum on the banks of the Grasse and St. Lawrence Rivers since 1903 and 1958. And like many other industries in the past, these two Alcoa plants in Massena, N.Y., discharged a stream of toxic pollutants into the water, air, and soil around them.
Now, only a few miles away, dozens of young Mohawk children at the Akwesasne Freedom School attempt to reclaim their Mohawk heritage and a connection with the natural world and traditional practices endangered in part by the area’s contaminated history.
Today, the majority of the $19.4 million settlement with Alcoa and the former Reynolds Metals Company will go toward healing past wounds to this rich ecological and cultural environment with a suite of proposed restoration projects.
A History of Pollution on the St. Lawrence
Starting in the late 1950s, Alcoa and Reynolds used polychlorinated biphenyls (PCBs) in hydraulic fluid and electrical equipment as they produced aluminum at these two factories. Nearby, General Motors Central Foundry (GM) also used PCBs in the hydraulic fluids when building automotive engines and in electric equipment. The PCBs from these three facilities in turn made their way into the St. Lawrence River, its tributaries the Grasse and Raquette Rivers, and the surrounding area.
Banned in 1979, PCBs are a group of persistent and highly toxic compounds which, in addition to causing cancer in animals, affects growth, behavior, reproduction, immune response, and neurological development. Manufacturing activities at these three factories released a slew of other industrial pollutants [PDF] that impacted the environment, including aluminum, fluoride, cyanide, and polycyclic aromatic hydrocarbons (PAHs, a hazardous component of oil, coal, and tar).
In 2000, Alcoa purchased Reynolds and as a result, Reynolds’ facility is now known as Alcoa East. Its sister facility, Alcoa West, is the longest continually operating aluminum facility in the world. The third, now-shuttered, General Motors factory sits next door to Alcoa East and has already paid approximately $1.8 million for environmental restoration in separate bankruptcy proceedings. Combined with $18.5 million from Alcoa’s settlement, the Alcoa and GM settlements will provide approximately $20.3 million for specific projects to restore access to recreational fishing, fish and wildlife, and Mohawk traditional practices and language.
Moving Toward Environmental Restoration
The St. Lawrence Environmental Trustee Council, a group of federal, state, and tribal governments which includes NOAA, has coordinated with the companies to assess the damages to ecological resources, recreational fishing, and the St. Regis Mohawk Tribe’s cultural resources. Due to the history of industrial pollution released from these factories into the St. Lawrence River watershed, the sediments, fish, birds, mammals, reptiles, and amphibians along the St. Lawrence, Grasse, and Raquette Rivers have all suffered. Under the U.S. Environmental Protection Agency and the New York State Department of Environmental Conservation, various cleanup activities, such as dredging and capping contaminated river sediments, have been attempting to remediate the polluted environment.
Improvements to spawning habitat and stocking of lake sturgeon is one of the restoration projects preferred by the natural resource trustees. (Saint Regis Mohawk Tribe)
As part of a process that moves beyond cleanup, the trustees, led by the St. Regis Mohawk Tribe, have identified preferred recreational fishing, ecological, and cultural restoration projects to compensate the public for the resulting environmental injuries.
For example, contaminants from the three facilities degraded adult and juvenile fish habitat for species such as the American eel (currently being considered for Endangered Species Act protection) and the state-threatened lake sturgeon. The presence of toxic PCBs triggered fish consumption advisories for the St. Lawrence, Grasse, Raquette, and St. Regis Rivers. In place since 1984, these advisories have resulted in an estimated 221,000–250,000 fewer fishing trips on these rivers, both in the past and into the future. In response, four new boat launches will be constructed and one existing launch will be upgraded to provide shoreline and in-river fishing access points.
The trustees also will protect and restore wetland and upland habitat, enhance stream banks, improve impeded fish and other wildlife passage through the rivers, enhance fish stocks and spawning habitat, and restore bird habitat. The preferred restoration projects are described in the St. Lawrence River Environment Restoration Compensation and Determination Plan [PDF]. The public can comment on this plan and on the Alcoa $19.4 million natural resource damage settlement, which includes $18.5 million for restoration and nearly $1 million in reimbursement for past environmental assessment costs.
Reconnecting to the Natural World
One of the most creative examples of the preferred restoration projects centers not on restoring natural resources such as sturgeon, a species important to the St. Regis Mohawk Tribe, but on restoring the unique culture of the Mohawks, which is tied closely to the natural world.
A tribal apprenticeship program will work to restore traditional Mohawk cultural practices, including basketmaking. (Akwesasne Museum and Cultural Center)
Grassy meadows on both sides of the Lower Grasse River were set aside for the Mohawks of Akewsasne by the Seven Nations of Canada Treaty of 1796. The name Akwesasne means “the land where the partridge drums,” a reference to the sound created by the rapids of the St. Lawrence River prior to the construction of dams.
The people of Akwesasne were directly impacted by the contamination from the Alcoa, Reynolds, and GM factories. An innovative tribal apprenticeship program will seek to restore traditional Mohawk cultural practices that have been lost or impaired since contamination limited use of the uplands, the rivers, and their natural resources. The tribe, as a trustee, has targeted four traditional areas for apprentices to receive hands-on training from experienced masters:
Water, fishing, and use of the river.
Horticulture and basketmaking.
Medicinal plants and healing.
Hunting and trapping.
The apprenticeship program will provide experience in directly harvesting, preparing, preserving, and producing traditional Mohawk cultural products while promoting Mohawk language in each aspect of the training.
Restoration funding also will support existing institutions and programs focused on recovering cultural practices and language injured by contaminants from these manufacturing sites.
Looking upstream on the Sheboygan River from the Pennsylvania Avenue Bridge in downtown Sheboygan, Wisconsin. This section of the river was dredged in 2011 to remove sediment contaminated with PCBs and PAHs. (NOAA/Jessica Winter)
One of my first introductions to the problems of environmental contamination was Wisconsin’s Sheboygan River. It empties into Lake Michigan, a rich recreational, commercial, and ecological area, but unfortunately, the Sheboygan has suffered from a past filled with toxic chemicals. As an intern in the U.S. Environmental Protection Agency’s Great Lakes National Program Office in 2006, I visited this scenic river in eastern Wisconsin to learn about the techniques used for cleaning up the river’s contaminated sediments. At the time, I didn’t know that I would return with NOAA’s Office of Response and Restoration to work on the restorative process that follows cleanup: natural resource damage assessment.
A Superfund Site in the Making
Throughout the 20th century, industrial facilities released the hazardous chemicals polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), metals, and more into the Sheboygan River and adjacent floodplains. These chemicals have been measured at high concentrations in the river sediments and fish, limiting the public’s ability to use and enjoy the Sheboygan River for years. For example, resident fish and waterfowl from the river are unsafe to eat because the high contaminant levels exceed U.S. Department of Agriculture standards. To address this contamination, the EPA’s Superfund Division has designated the lower 14 miles of the Sheboygan River and the adjacent floodplains for cleanup.
On my most recent visit to the river in the fall of 2012, cleanup crews were in their final season of work on a project that has been underway for many years, beginning with emergency sediment removal in 1978. But how do you actually “clean” a polluted river like the Sheboygan?
“Geotubes,” show here filled with sediment, were used to remove contaminants from Sheboygan river sediments. In the background, pipes collected weepwater which oozed out of the geotubes and left behind contaminated sediments. (U.S. Environmental Protection Agency)
For the upstream stretch of the river, completed in 2006–2007, a crew had to suck up contaminated sediments from the riverbed, suspend them in water so they flow as slurry, and then pump the slurry through a pipeline. Next, they pumped it into “geotubes,” large porous bags that allow the river water to seep out but keep the sediment and solid pollutants inside. A wastewater treatment plant removed any remaining contamination from the water. Once the sediment was dry enough, it was transported to a specially designed hazardous waste landfill. Cleanup in the downstream stretch of the river in 2011–2012 used similar methods, as well as an excavator to scoop up some of the sediments and embedded pollutants.
Gearing up for Restoration
As this cleanup was winding down, my NOAA colleagues and I traveled to Sheboygan, Wis., to meet with other federal and state scientists studying the affected area. NOAA, the U.S. Fish and Wildlife Service, and the Wisconsin Department of Natural Resources serve as trustees for the public while conducting a Natural Resource Damage Assessment (NRDA). During this process, the trustees collect and evaluate data to identify the natural resources that have been injured by contamination and to quantify the resulting injuries to the environment. For example, injuries might include increased tumor rates in fish or reduced prey available for fish to eat. Luckily for us, the Sheboygan River is well-studied; we have data investigating animal populations and habitat quality from the 1970s to the present.
Fish consumption advisories, as seen posted here along the river, have been in place on the Sheboygan River since 1979. (Wisconsin Department of Natural Resources/Vic Pappas)
Once the trustees know precisely what the injuries are from this pollution, they work with the public to choose projects that will address those injuries. For example, this might include creating or enhancing wetlands that will provide better areas for fish to find food. Trustees then require the parties responsible for the contamination either to fund or implement these restoration projects themselves.
In 2012, this restoration process kicked off when the trustees undertook a preliminary assessment. They examined the current state of scientific information on the Sheboygan River’s sediments, soils, water, invertebrates, fish, birds, mammals, and reptiles to determine whether it is reasonable to pursue a full damage assessment, which would compensate the public for the natural resources hurt by the Sheboygan’s history of toxic chemicals. The preassessment screen [PDF] documents this work.
What did they conclude after the preliminary assessment? That injury to these resources was likely and that damage assessment is warranted. Next, the trustees will develop an Assessment Plan that will describe the methods that will be used to quantify damages. Trustees will invite the public to comment on the Assessment Plan.

The latest round of aquatic restoration projects for the Housatonic River will also indirectly improve water quality, increase buffering during coastal storms, and reduce runoff pollution into the river. (NOAA)
NOAA, the U.S. Fish and Wildlife Service, and the State of Connecticut released a proposal to use approximately $2 million from a 1999 settlement with General Electric Company (GE) to fund projects to increase fish habitat and restore marshes on the Housatonic River. Between 1932 and 1977, GE discharged polychlorinated biphenyls (PCBs) and other chemical wastes from its facility in Pittsfield, Mass, into the Housatonic River, which runs through western Massachusetts and Connecticut. As a result, the Housatonic’s fish, wildlife, and their habitats suffered from the effects of these highly toxic compounds.
Part of an amendment to the 2009 restoration plan [PDF] for the Housatonic site, these latest projects highlight aquatic restoration because the original plan primarily focused on recreational and riparian restoration, with more than half of those projects already complete. The amendment identifies seven preferred restoration projects and three non-preferred alternatives to increase restoration of injured aquatic natural resources and services. These projects aim to more fully compensate the public for the full suite of environmental injuries resulting from GE’s decades of PCB contamination by:
Enhancing wetland habitat for birds, fish, and other wildlife.
Supporting native salt marsh restoration by eradicating nonnative reeds and removing large debris (e.g., plywood and lumber).
Restoring migratory fish and wildlife passages by removing dams and constructing bypass channels.
Promoting recreational fishing, other outdoor activities, and natural resource conservation.
The 1999 legal settlement with GE included $7.75 million for projects in Connecticut aimed at restoring, rehabilitating, or acquiring the equivalent of the natural resources and recreational uses of the Housatonic River injured by GE’s Pittsfield facility pollution. Settlement funds grew to more than $9 million in an interest-bearing fund. NOAA and its co-trustees are using the majority of the remaining $2,423,328 of those funds to implement these additional aquatic natural resources projects.
Public comments and additional project proposals for this draft amendment to the restoration plan will be accepted through March 11, 2013.

According to the report, “Fish not only absorb PCBs directly from the river water but are also exposed through the ingestion of contaminated prey, such as insects, crayfish, and smaller fish…New York State’s ‘eat none’ advisory and the restriction on taking fish for this section of the Upper Hudson has been in place for 36 years.” (NOAA)
The Hudson River Natural Resource Trustees, including NOAA, released a report today outlining the magnitude of toxic chemical pollution in New York’s Hudson River. The report, “PCB Contamination of the Hudson River Ecosystem” [PDF], documents six years of data and analysis showing that the Hudson River, for more than 200 miles below Hudson Falls, N.Y., is extensively contaminated with polychlorinated biphenyls (PCBs).
Starting in 1947 and for approximately 30 years, manufacturing plants operated by General Electric Company (GE) discharged PCBs into the upper Hudson River, with additional releases of PCBs occurring as well.
According to the report, PCBs are a “group of highly toxic compounds that are known to cause cancer, birth defects, reproductive dysfunction, growth impairment, behavioral changes, hormonal imbalances, damage to the developing brain, and increased susceptibility to disease in animals.” Hazardous at even very low levels, they make their way up the food chain and become stored in the tissues of wildlife and fish, posing a health threat if people consume them.
Analysis of the river from 2002 to 2008 shows that PCBs permeate nearly every part of the river: surface waters, sediments, floodplain soils, fish, birds, wildlife, and other natural resources. The report further documents decades of high levels of PCBs and likely harmful effects on living organisms exposed to the contamination in the Hudson River. PCB levels in fish were often 10 or more times the U.S. Food and Drug Administration’s (FDA) standards for safe consumption (pp. 10) and in water samples tested “10 to 10,000 times higher than that deemed safe for aquatic life, fish-eating wildlife and human consumers of fish” (pp. 5).
As a result of this pollution, the public has lost the use of these natural resources, for example, due to restrictions and advisories for catching and eating fish and navigational losses due to contamination of the Champlain Canal.
