The Great Lakes Ecological and Economic Protection Act was introduced by Senators Carl Levin (D-MI) and Mark Kirk (R-IL), co-chairs of the Senate Great Lakes Task Force, along with Senators Debbie Stabenow (D-MI), Amy Klobuchar (D-MN), Sherrod Brown (D-OH), Richard Durbin (D-IL), Al Franken (D-MN), Charles Schumer (D-NY) and Tammy Baldwin (D-WI).
In addition to reauthorizing the Great Lakes Legacy Act, which provides support for communities to clean up waterways that are designated Areas of Concern (AOC) the United States and Canada, the new legislation would continue funding the Great Lakes Restoration Initiative and the EPA Great Lakes National Program Office.
The 10-minute video, produced by Illinois-Indiana Sea Grant and Wisconsin Sea Grant, explores Great Lakes waterways blighted by decades of industrial discharges like heavy metals, oil, and chemicals such as PCBs and PAHs. The 2002 Great Lakes Legacy Act created an initiative to clean up contamination in these AOCs. There are currently 29 AOCs in the United States. The habitat, water, and sediment quality have become severely degraded at these sites.
The video informs anglers, boaters, residents, and local businesses of the benefits that can come from a remediated AOC through the Legacy Act. The procedures and successes are the result of strong partnerships among states, municipalities, non-governmental organizations and businesses. Under this voluntary, collaborative program, the EPA and its non-federal partners have allocated almost $400 million toward sediment remediation.
As of September 2012, the program has removed or capped 2.1 million cubic yards of degraded sediment. But more waterways need to be cleaned up, and community involvement is essential.

Illinois’ beach fronts got a bit of good news last week as a recent report pointed to improving water conditions and reduced contamination.
From The Chicago Tribune:
“The report compiles data on E. coli levels collected by local agencies and submitted to the U.S. EPA. E.coli, which can cause serious illnesses and infection, can be a predictor of other contaminants in the water, said Henry Henderson, Midwest director for NRDC.
Chicago’s Montrose Dog Beach and Rainbow Beach were the most contaminated beaches along Illinois’ Lake Michigan shoreline, according to the report. A variety of factors can change how a particular beach might test on any given day.
The study also found that Illinois’ 65 Lake Michigan beaches saw a combined 334 closings and swimming advisory days last year, a decrease from 483 combined days in 2011. The majority of those closings and advisories were caused by unknown contamination sources, according to the report.”

Recent research has shown that pharmaceuticals and personal care products can cause significant problems for waterways, affecting not only water quality but also negatively impacting the processes that plants and animals need to survive and thrive.
One way that those products are causing pollution in the Great Lakes may not just be due to the chemicals they are made from, though.
From Scientific American:
“Rather, small plastic beads, known as micro plastic, are the offenders, according to survey results to be published this summer in Marine Pollution Bulletin. ‘The highest counts were in the micro plastic category, less than a millimeter in diameter,’ explained chemist Sherri ‘Sam’ Mason of the State University of New York at Fredonia, who led the Great Lakes plastic pollution survey last July. ‘Under the scanning electron microscope, many of the particles we found were perfectly spherical plastic balls.’
Cosmetics manufacturers use these micro beads, or micro exfoliates, as abrasives in facial and body scrubs. They are too tiny for water treatment plants to filter, so they wash down the drain and into the Great Lakes. The biggest worry: fish such as yellow perch or turtles and seagulls think of them as dinner. If fish or birds eat the inert beads, the material can deprive them of nutrients from real food or get lodged in their stomachs or intestines, blocking digestive systems.”
These latest findings help provide additional information on how these common products can cause environmental problems. For more information, read the complete article at the link above and visit our Unwanted Meds website.

Lake Erie, one of the Great Lakes that began to rebound significantly thanks to the Clean Water Act and several cleanup projects, is being threatened by toxic blue-green algae. Fed by fertilizers and runoff, the algae can deplete oxygen levels in the water and be detrimental to the lake’s health.
From The Plain Dealer:
“The Western Basin of Lake Erie, located roughly from Toledo to Huron, is becoming seriously affected with toxic blue-green algae. During the summer months, the algal blooms have been so bad that swimmers have emerged from Lake Erie covered in green slime. So far, swimming in Lake Erie has not been prohibited as it was in Grand Lake St. Mary’s, however, the thick algal blooms are not very inviting to swimmers and tends to affect the taste of our drinking water.
The enjoyment of Lake Erie for boating and fishing has also become hampered by the costs to repair clogged engines and the costs of reduced economic drivers, such as fishing charters and other recreational opportunities. We are dangerously close to severely restricting our use and enjoyment of one of the world’s greatest natural resources.”

Governors of the Great Lakes states and Canadian officials have recently vowed to work more closely to combat aquatic invasive species that threaten the Great Lakes system, but disagreements over the best course(s) of action linger.
From The Detroit News:
“But the difficult balancing act of weighing the economic and transportation interests of the eight states and two Canadian providences against the long-term ecological stability of the Great Lakes and St. Lawrence Seaway was on full display Saturday at the Mackinac Island summit of regional officials.
Illinois Gov. Pat Quinn, whose state has faced criticism and lawsuits for moving too slow to combat the invading Asian carp, surprised fellow governors by shifting the state’s position to support the sealing off of the manmade Chicago waterways that connect the Mississippi River to the Great Lakes.
‘Ultimately, I think we have to separate the basins,’ Quinn said at the first meeting of the Council of Great Lakes Governors in eight years. ‘I really feel that is the ultimate solution. We have to do it.’
Quinn’s endorsement of separating the two basins, seen as a potential breakthrough by environmentalists, was criticized by neighboring Indiana Gov. Mike Pence, even as the Great Lakes leaders sought to appear united on other issues at the summit.
Pence said his state remains opposed to closing the Chicago Sanitary and Ship Canal’s connection to Mississippi River tributaries that provide a southern transportation route for freighters carrying $1.9 billion in goods annually from Indiana factories and farms.”

IISG’s science writer, Anjanette Riley, is at the 2013 International Association for Great Lakes Research conference at Purdue University. She’ll be blogging from the sessions all week providing an inside look at the newest research on the health of the Great Lakes. Here’s today’s post:
“The Great Lakes got their report card this morning during a three-part presentation by members of the State of the Lakes Ecosystem Conference (SOLEC). It wasn’t good. In two of the three categories used to evaluate the health of the basin—water quality, aquatic wildlife, and landscapes and natural processes—the lakes were declared ‘fair and deteriorating.’ It was only in the third category, which covers things like habitat restoration and land use, that the region showed clear signs of overall improvement.
Most of the drivers behind worsening water quality and wildlife health likely sounded familiar to everyone in the room. Clodophora, a green algae common in the region, is washing up on more and more shorelines and threatening drinking water. New contaminants are being introduced to aquatic ecosystems. Invasive species are out-competing native fish and permanently changing the food web. And coastal wetlands used by fish for spawning are disappearing.
What was not as familiar, at least to me, were concerns over the spread of nutrients throughout the lake. In recent years, nutrients that are carried into the lakes in stormwater runoff, like phosphorus, have built up along the coastline instead of being pushed to deeper waters. In nearshore waters, these trapped nutrients mean more algae; so much more that it can block sunlight and reduce oxygen that fish and other wildlife need to survive. Offshore, though, the loss of nutrients means that there is not enough phytoplankton for wildlife to feed on. Paul Horvatin, one of the presenters, told the room that it is still unclear why the nutrients are not moving as they should.
But there were some improvements over past years. The most notable to me was the growing number of restoration and dam removal projects that are opening up new waterways for fish to spawn, restoring the natural flow of rivers and tributaries, and reconnecting habitats, some of which have been divided for close to 100 years. The region has also seen improvements in land use practices, such as reforestation and increased reliance on green infrastructure. Extensive development and agriculture in the southern part of the Great Lakes basin, though, have caused enough damage in the past that more modern changes to land use practices and policies will take time to really show results. These ecosystems are more stressed then their northern counterparts and will require ongoing restoration and impact mitigation.”

IISG’s science writer, Anjanette Riley, is at the 2013 International Association for Great Lakes Research conference at Purdue University. She’ll be blogging from the sessions all week providing an inside look at the newest research on the health of the Great Lakes. Here’s today’s post:
“It was during a presentation today on the impacts of climate change to water levels that I learned a startling fact: Lake Erie’s water level trends have in essence made a 180 degree turn. Historically, water levels in the Great Lakes are at their highest in summer when increased rain and stormwater runoff add more water to the lakes than they lose to evaporation, and levels are lowest in the winter months. In recent decades, though, this trend has been reversing, leaving water levels higher in January than they are in June.
According to data collected by the Great Lakes Environmental Research Lab (GLERL), one of the biggest driving forces behind this shift is increased evaporation over the lake during the hot summer months.
Evaporation is also a primary culprit in Lake Superior’s falling water levels. Here, though, warmer water temperatures that mean less ice in winter are causing greater evaporation across seasons. And less water is entering the lake from rain and stormwater runoff.
The story is different still in Lakes Michigan and Huron, where water levels reached an all-time low in the 1990s and have largely stayed there since.
Of course, there is still some variation in water levels year over year. The water in Lake Erie, in fact, rose by almost 3 feet over the course of just four months in 2011. But these jumps, as the presentation attendees were told, appear to be the exception to the rule. In these three lakes, water levels are trending down.”

Swimmers, boaters, and anglers visiting Indiana’s coastline this summer will again be able to learn about conditions in Southern Lake Michigan thanks to real-time data collected by the Michigan City buoy. The buoy, launched for the first time last fall, returned to its post four miles from shore last week to collect data on wave height and direction, wind speed, and air and surface water temperatures. It will stay in the water until November.
The relaunch comes just in time to help make summer trips to Michigan City and the Indiana dunes safer. Throughout the season, scientists at the National Weather Service (NWS) in northern Indiana will use wave height and frequency data collected by the buoy to better anticipate likely locations of strong waves and rip currents that cause dangerous swimming conditions. The only one of its kind in the Indiana waters of the lake, the Michigan City buoy gives forecasters access to historically unavailable nearshore data where conditions are much different than at the center of the lake. Real-time data from the buoy has already helped NWS improve their wave height forecasts.
“This information is vital for NWS forecasters to access and accurately forecast the potential for dangerous swimming and boating conditions along southern Lake Michigan,” said John Taylor, a meteorologist with the NWS office in northern Indiana. “Our hope is that by accurately forecasting when high waves and rip currents along the shoreline will result in dangerous swimming conditions, we can reduce the number of tragic drownings that occur in these waters every summer.”
The site lets visitors see real-time snapshots of lake conditions—updated every 10 minutes—as well as trends over 24-hour and 5-day periods.
And this year, the Michigan City buoy joins the ranks of environmental monitors that contribute to NOAA’s National Data Buoy Center. The addition makes it possible for people to easily access data older than five days and track trends over longer periods of time. This archived data is particularly important for researchers and natural resource managers who rely on the buoy’s data to improve weather forecasts, protect water quality, and predict where best to fish.
The buoy launch also coincides with Rip Current Awareness Week, and is just one piece of a larger effort to protect people from the dangers of rip currents. Visit the Rip Current Awareness Week website to learn more about rip currents and what you can do to protect yourself this summer.

IISG’s science writer, Anjanette Riley, is at the 2013 International Association for Great Lakes Research conference at Purdue University. She’ll be blogging from the sessions all week providing an inside look at the newest research on the health of the Great Lakes. Here’s today’s post:
“There is more food for Asian carp in Lake Michigan than people thought. In a morning filled with new insights into these invasive species’ biology and potential impact in the Great Lakes, this fact rang the loudest for me. I have read some of the research in recent years speculating that Asian carp could not survive in much of the Great Lakes, which have less of the phytoplankton and zooplankton than the ravenous eaters need. What my fellow session attendees and I learned this morning, though, is that the plankton population has been underestimated. There are more–much more–of the smallest species living in the nearshore waters of Lake Michigan than previously believed.
According to researchers from the Illinois Natural History Survey, the cause of the miscalculation is a common testing method that uses a filter too large to trap many of the microscopic species in the lake. Additional testing measures show that the number of some plankton species found in the lake is roughly the same as in rivers where Asian carp are known to thrive, like the Ohio and Missouri Rivers. And there are plankton species in the lake that are not found in many of these waterways. Taken together, this means that likelihood that Asian carp can make Lake Michigan their home may be higher than previous data has indicated.
The session this morning also taught me that carp will branch away from their favorite dish to eat the particulates from decomposed animals and plants that line the floors of lakes and rivers. These exist in much higher numbers than plankton and their stock is continuously replenished as aquatic matter dies. Although it is still unknown whether Asian carp would choose this food over others (or eat it only when there is nothing else), this could mean that plankton in the Great Lakes may not have to bear the brunt of the carp’s huge diet alone if the invasive fish were ever to take up residence.”
In addition to reauthorizing the Great Lakes Legacy Act, which provides support for communities to clean up waterways that are designated Areas of Concern (AOC) the United States and Canada, the new legislation would continue funding the Great Lakes Restoration Initiative and the EPA Great Lakes National Program Office.
