(Beyond Pesticides, March 4, 2015) The 9th U.S. Circuit Court of Appeals has agreed to hear the case brought by beekeepers challenging the U.S. Environmental Protection Agency’s (EPA) approval of a toxic pesticide known to be toxic to bees. In 2013, the beekeepers filed suit against the agency, citing that the new chemical, sulfoxaflor, as further endangering bees and beekeeping and noting that their concerns were not properly addressed by EPA before registration was granted. Sulfoxaflor is a sub-class of the neonicotinoid pesticides that have been linked to global bee declines. The Court has agreed to hear the case on April 14, 2015. The case, Pollinator Stewardship Council v. EPA, which requests changes to EPA’s product label for sulfoxaflor, was first filed July 2013. The petitioners include the Pollinator Stewardship Council, the American Honey Producers Association, the National Honey Bee Advisory Board, the American Beekeeping Federation, and beekeepers Bret Adee, Jeff Anderson and Thomas Smith. The beekeeper groups are represented by Earthjustice. The case is one of a number of pending legal cases on EPA’s pesticide decisions under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), including one submitted March 2013 by Beyond Pesticides, the Center for Food Safety, beekeepers, […]

Congress heeds call to action and introduces legislation as pressure mounts on White House Task Force to issue meaningful recommendations March 4, 2015 (Washington, DC)””A coalition of beekeepers, farmers, business leaders, environmental and food safety advocates rallied in front of the White House and delivered more than 4 million petition signatures today calling on the Obama administration to put forth strong protections for bees and other pollinators. This action anticipates the Pollinator Health Task Force recommendations, expected later this month. The task force, announced by the White House this past June, is charged with improving pollinator health through new agency regulations and partnerships. The assembled groups demand that the recommendations include decisive action on rampant use of neonicotinoids, a class of systemic insecticides scientists say are a driving factor in bee declines. The rally coincided with both a D.C. metro ad campaign and Representatives Earl Blumenauer (D-OR) and John Conyers’s (D-MI) reintroduction of the Saving America’s Pollinators Act, which would suspend the use of four of the most toxic neonicotinoids until the Environmental Protection Agency (EPA) conducts a full review of their safety. Representative Blumenauer, said, “Pollinators are not only vital to a sustainable environment, but key to a stable […]

(Beyond Pesticides, March 3, 2015) Over 125 conservation, beekeeping, food safety, religious, ethnic and farming advocacy groups are urging President Obama and the Environmental Protection Agency (EPA) to take swift and meaningful action to protect honey bees and other pollinators from toxic pesticides. Groups, including Beyond Pesticides, raised their voice through a letter sent in advance of a pending report from the White House Pollinator Task Force, which was established last June by the President with the goal to “reverse pollinator losses and help respond populations to healthy levels.” Last October the White House announced it would miss its self-assigned deadline, delaying the urgent action that is needed to address this crisis. The letter urges President Obama and executive agencies to take action against a class of pesticides called neonicotinoids, systemic poisons that are devastating bee populations. They are also threatening the nation’s food supply, since one-third of the food consumed in the United States is pollinated by bees. “Through bold and decisive action from the White House and EPA, we can begin to reverse bee declines and protect pollinator populations for future generations,” said Nichelle Harriott, Science and Regulatory  Director at Beyond Pesticides. Among other steps the  letter calls […]

(Beyond Pesticides, February 27, 2015) New research from the University of Minnesota presents some of the first evidence linking the bee-killing insecticides known as neonicotinoids to monarch butterfly deaths. The study finds that milkweed plants, which monarch butterflies need to survive, may also retain neonicotinoids from nearby plants, making milkweed toxic to monarchs. Monarch population numbers have fallen by 90% in less than 20 years. This year’s population was the second lowest since careful surveys began two decades ago. The critical driver of monarch decline  is the loss of larval host plants in their main breeding habitat, the midwestern Corn Belt. Monarchs lay eggs exclusively on plants in the milkweed family, the only food their larvae will eat. University of Minnesota entomologist Vera Krischik, Ph.D. fed butterflies milkweed plants treated with the neonicotinoid insecticide known as imidacloprid in amounts that might typically be found on backyard plants. While adult monarchs and painted lady butterflies were not affected, which, according to Dr. Krischik, indicates the ability of the adults to detoxify, the larvae of both species of butterflies died. During the course of the study, larvae fed on the treated plants for seven days. “For the monarch, nobody was left that […]

(Beyond Pesticides, February 26, 2015) Yesterday, the Environmental Protection Agency (EPA) granted Florida citrus growers an emergency exemption to use the bee-killing pesticide clothianidin to control Asian Citrus Psyllid (ACP), a pest that causes “citrus greening,” a devastating citrus plant disease. Clothianidin, which is not currently registered for use on citrus, is part of a class of neurotoxic, systemic insecticides called neonicotinoids, which have been implicated in global honey bee declines and suspended in the European Union. “EPA needs to assist in stopping the deadly use of pesticides that harm bees, butterflies, and birds with sustainable practices, rather than imperil pollinators with its decisions,” said Jay Feldman, executive director of Beyond Pesticides, a health and environmental advocacy group. He continued, “We understand the immediate chemical needs of chemical-intensive agriculture for increasingly toxic and persistent chemicals, but urge EPA to help stop the treadmill, lest it allow irreversible harm to the environment, biodiversity, and human health.” Beyond Pesticides is urging EPA to require that growers adopt a management plan in order to apply clothianidin. “Ultimately, EPA should be requiring growers to adopt integrated organic systems to manage pests, as a part of an emergency permit,” said Mr. Feldman. Read Beyond Pesticides’ […]

(Beyond Pesticides, February 20, 2015) A broad-based coalition is urging Canada’s Prime Minister Stephen Harper to put a stop to proposed changes to federal aquaculture regulations, citing damage to the environment and existing businesses. The proposed amendments to the federal Fisheries Act would exempt the aquaculture industry from provisions that “prohibit the release of deleterious substances into water frequented by fish.” Coalition members are worried that the changes will result in pesticides routinely being dumped into the Bay of Fundy,  located between the Canadian provinces of Nova Scotia and New Brunswick, and remove Environment Canada’s role in aquaculture activities, said spokeswoman Maria Recchia, the executive director of the Fundy North Fishermen’s Association. Aquaculture, which refers to the breeding, rearing, and harvesting of aquatic organisms such as fish, shellfish, and plants, provides half of the world’s seafood. According to  Food and Water Watch, offshore aquaculture follows an industrial agriculture model which grows thousands of animals in a confined environment. For fish, however, this confined space is in the ocean, meaning all of the waste products from the operation flow directly into the ocean. This includes excess feed and chemicals that are used, such as antibiotics and pesticides, to treat or prevent […]

(Beyond Pesticides, February 17, 2015) The Center for Biological Diversity filed a lawsuit in federal court in California February 12 against the U.S. Fish and Wildlife Service (FWS) for failing to ensure that three widely used pesticides ””atrazine, 2,4-D and alachlor”” do not jeopardize the survival of two Bay Area endangered species, the delta smelt and Alameda whipsnake. FWS has yet to act on a request from the U.S. Environmental Protection Agency (EPA) to determine whether measures are needed to protect the delta smelt and Alameda whipsnake from exposure to these pesticides. “These pesticides are known to harm wildlife even in miniscule amounts, so it’s long past time that we start taking commonsense steps to protect endangered species, our water and ourselves,” said Brett Hartl, endangered species policy director at the Center. “Putting off any analysis of the harms caused by pesticides for six years is simply unacceptable, and has set back the recovery of these two species substantially.” Scientific research has shown that atrazine can harm the development of amphibians at exposures of just a few parts per billion, is toxic to fish, reptiles, mammals and birds, and may elevate risks of birth defects in people. Up to 80 […]

(Beyond Pesticides, February 13, 2015) With the U.S. Environmental Protection Agency’s (EPA)  nod to the pesticide industry on expanded uses of the herbicides 2,4-D and glyphosate, environmental groups are charging that the agency violated the Endangered Species Act (ESA).  Repeating a pattern of putting the environment in harm’s way through violations of  federal endangered species  law, a lawsuit filed Friday  documents   EPA’s  failure to consult with the U.S. Fish and Wildlife Service (FWS) regarding the impact of the herbicide on two endangered species —the whooping crane and the Indiana bat— with the recent approval of Dow AgroSciences’ herbicide, Enlist Duo, for use on genetically engineered (GE) crops in six midwestern states. Enlist Duo is an herbicide that incorporates a mix of  glyphosate  and a new formulation of  2,4-D, intended for use on GE Enlist Duo-tolerant corn and soybean crops. Approved for use on GE corn and soybeans that are engineered to withstand repeated applications of the herbicide, the creation of 2,4-D-tolerant crops and EPA’s approval of Enlist Duo is the result of an overuse of glyphosate, an ingredient in Monsanto’s Roundup. The misuse resulted in an infestation of glyphosate-resistant super weeds which can now be legally combatted with the […]

(Beyond Pesticides, February 10, 2015) Scientists at the Universities of Dundee and St. Andrews in Scotland have found evidence confirming that the levels of neonicotinoid (neonic) pesticides bees are likely to encounter in the wild impair the pollinator’s brain cells, resulting in colony declines. Bees and other wild pollinators provide services of over $125 billion globally, but are experiencing widespread and consistent losses that have the potential to increase global malnutrition and disease if not properly addressed. Although countries and regions across the globe have taken action to suspend or restrict the use of neonic pesticides in light of their threat to bees, policymakers in the U.S. continue to delay, impose inadequate changes, or even introduce new bee-toxic chemicals. The recent study, Chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee (Bombus terrestris), published in the Journal of the Federation of American Societies for Experimental Biology, finds a mechanistic explanation for previous findings that observed poor navigation and foraging in colonies of bumblebees exposed to neonicotinoids. To do this, researchers exposed bumblebees to doses of the neonics imidacloprid and clothanidin generally expected to be seen in the field (10 nanomoles[nM]/2.1ppb), and measured the amount that accumulated […]

(February 9, 2015, Beyond Pesticides) A report, Monarchs in Peril: Herbicide-Resistant Crops and the Decline of Monarch Butterflies in North America, released by Center for Food Safety (CFS) last week, reveals the devastating  impact of Monsanto’s and the nation’s biggest selling herbicide, Roundup (glyphosate), on the survival  of monarch butterflies. The herbicide is  used to treat  millions of acres of herbicide-tolerant  genetically engineered (GE) crops, eliminating the monarchs’ sole source  of food, milkweed, and approaching  a collapse of their population, which has plummeted over the past 20  years. The report cites findings that  glyphosate use on Roundup Ready  (glyphosate-tolerant) crops has nearly eradicated milkweed around farmland in the monarchs’ vital midwest breeding ground. At the urging of scientists and public interest groups, the U.S. Fish and Wildlife Service (FWS) is currently considering listing the monarch as a threatened species under the Endangered Species Act (ESA). “This report is a wake-up call. This iconic species is on the verge of extinction because of Monsanto’s Roundup Ready crop system,” said Andrew Kimbrell, executive director at Center for Food Safety. “To let the monarch butterfly die out in order to allow Monsanto to sell its signature herbicide for a few more years is […]

(Beyond Pesticides, January 28, 2015) Global decline of pollinators and pollination services will have a devastating impact on the nutritional health of people in developing countries, especially women and children, if left unabated, according to a new study from scientists at the University of Vermont and Harvard University. This research is the first to examine how pollinators influence nutrient intake and the risk of nutrient deficiency. It also comes at a time when policy makers are slow to find long-term sustainable solutions to reversing pollinator declines, despite mounting scientific evidence urging immediate action. Pollination services are valued at over $125 billion globally and pollinators are responsible for one in three bites of food we eat. However, pollinators like honey bees, wild bees, butterflies and others are in decline around the globe, with many beekeepers, scientists, and environmental activists singling out pesticides as a major contributing factor. But despite suggestions that pollinators are critical not only for global food supply, but specifically human nutritional health, there has not been any research to support this claim until now. The study, “Do Pollinators Contribute to Nutritional Health,” published in PLoS ONE, combined data on crop pollination requirements, food nutrient densities, and actual human […]

(Beyond Pesticides, January 26, 2015) Last week, the U.S. Environmental Protection Agency (EPA) announced it completed the registration of a new pesticide, flupyradifurone, that would be marketed as an alternative to neonicotinoid pesticides, and “safer for bees.” A closer look at this chemical reveals that the agency is grossly misleading the public on the ecological safety of flupyradifurone since the chemical is systemic, persistent, and highly acutely toxic to adult honey bees. At a time when bees are declining, advocates say it is inappropriate for EPA to introduce yet another bee toxic chemical to the market. Flupyradifurone (“Sivanto”) is a new systemic, butenolide insecticide from Bayer CropScience that is to be used on crops such as citrus, cotton, potatoes and many others, and also as seed treatment. Note: EPA is still considering soybean seed treatment. The chemical is a neurotoxic insecticide that can inhibit nicotinic acetylcholine receptors (nAChR) in the nervous system. Neonicotinoids, widely linked to devastating health impacts on bees,  affect the nervous system in the same way. However, EPA states that flupyradifurone differs from neonicotinoids because of the way it binds to the receptors and  is metabolized. However, most troubling is that, based on EPA’s registration documents, the […]

(Beyond Pesticides, January 23, 2015) Pesticide-centered Program Approved Despite 30,000 Opposition Letters. Eleven groups, including Beyond Pesticides and the City of Berkeley, sued the California Department of Food and Agriculture yesterday over the agency’s approval of a statewide “pest management” plan that allows pesticide spraying on schools, organic farms and residential yards, including aerial spraying over homes in rural areas. California regulators approved the program despite tens of thousands of public comment letters calling for a less toxic approach that would protect the vitality and resilience of the state’s food system and the economic interests of organic farmers. “Environmental review laws are there to prevent abuses,” says Jay Feldman, Executive Director of Beyond Pesticides, “Agencies cannot make unilateral decisions to ignore mandatory health and environmental safety standards.” “The state offers no evidence to support its conclusion that this pesticide-centered program will have no effect on our health,” said Debbie Friedman, cofounder of MOMS Advocating Sustainability. “As a parent, I am particularly disturbed that health risks of pesticide residues for children aged two and under are dismissed based on the absurd reasoning that infants spend most of their time indoors.” The approved program allows the state to use, without any additional […]

(Beyond Pesticides, January 8, 2015) At the close of 2014, Thurston County in Washington State became the first county government to ban the use of neonicotinoid insecticides on county-owned and managed lands. The ban comes in the form of an amended pest and vegetation policy and was passed by County Commissioners by a 3-0 vote in favor of the amendment. According to The Olympian, the ban will impact 77 acres of county facilities, 2,646 acres of parks, 47.1 miles of trails, and one mile of right-of-way landscape. Commissioners instituted the ban because of concerns over the pesticides effects on pollinators. Neonicotinoids (“neonics”) are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. Recent scientific research has uncovered many uncertainties and new information on neonic-induced adverse impacts with regard to the environmental fate and sublethal exposure on foraging behavior of pollinators. Thurston County’s ban is not the first time the county has taken up the issue of neonics in defense of pollinators. In 2013, the Commissioners petitioned the Washington State Department of Agriculture (WSDA) […]

(Beyond Pesticides, January 6, 2015) At the close of 2014, the U.S. Fish and Wildlife Service (FWS) announced plans to conduct a year-long status review of the monarch butterfly to determine whether the species is eligible for protection under the Endangered Species Act (ESA). FWS is taking this action as result of an August 2014 legal petition filed by health and environmental groups that presented substantial information indicating that listing under the ESA may be warranted. In November 2014, Beyond Pesticides joined over 200 environmental groups and businesses in a letter asking for federal protection for monarch butterflies in the wake of shocking declines. The North American monarch butterfly population fell by 90 percent in the past 20 years, dropping from a high of approximately  one billion in the mid-1990s to fewer than 35 million butterflies in the winter of 2013-2014— the lowest number ever recorded. Each year monarch butterflies travel over 2,000 miles between Canada, the U.S., and Mexico, across multiple generations, to reach their winter hibernation grounds in late October. As FWS indicates, this journey has become “more perilous for many monarchs” due to threats along their migratory paths. Scientists believe the butterfly’s decline is being driven in […]

(Beyond Pesticides, December 3, 2014) The U.S. Department of Agriculture (USDA) announced last week that nearly 2,500 applicants will receive disaster assistance through the Emergency Assistance for Livestock, Honey Bees, and Farm-Raised Fish Program (ELAP) for losses suffered from Oct. 1, 2011, through Sept. 30, 2013. The program, re-authorized by the 2014 Farm Bill, provides disaster relief for farmers and producers not covered by other agricultural disaster assistance programs. Beekeepers who reported losses due to colony collapse disorder will be eligible, a move that many in the beekeeping industry welcome. ELAP provides disaster relief to livestock, honey bee, and farm-raised fish producers not covered by other agricultural disaster assistance programs. Eligible losses may include excessive heat or winds, flooding, blizzards, hail, wildfires, lightning strikes, volcanic eruptions, and diseases, or in the case of honey bees, losses due to colony collapse disorder. According to USDA, beekeepers, most of whom suffered honey bee colony losses, represent more than half of ELAP recipients. Enrollment for the program began last spring and ended in August 2014, and eligible farmers, beekeepers and producers must have submitted documentation of losses for enrollment in the program. Beekeepers have been experiencing historical losses in their bee hives and […]

(Beyond Pesticides, November 14, 2014) In the face of staggering declines of monarch butterflies, more than 40 leading scientists and 200 organizations and businesses this week urged the Secretary of the Department of the Interior, Sally Jewell, to protect these butterflies under the Endangered Species Act (ESA). These groups and scientists are supporting the formal petition to the U.S. Fish and Wildlife Service (FWS) submitted this summer, which seeks federal protection for monarch butterflies. Forty scientists from around the U.S. and Mexico signed on to a letter requesting protected status for the butterflies and for FWS to recognize the importance of continued research by scientists and citizen scientists in understanding and conserving the monarch butterfly and its habitat. The scientists also request FWS to streamline the permitting process, so that scientific and conservation research and citizen science activities are encouraged rather than deterred by a listing. In a separate letter, over 200 environmental groups and businesses called on FWS to take swift and effective action by granting the monarch butterfly protection as a threatened species under the ESA. Both letters come in support of a formal petition to FWS seeking federal protection for monarchs. The petition was filed in August […]

(Beyond Pesticides, November 12, 2014) The Oregon Department of Agriculture (ODA) has issued two civil penalties totaling $16,000 in connection with a pesticide application of imidacloprid, a chemical in the neonicotinoid class of insecticides connected to widespread bee decline, this summer that resulted in the death of nearly 1,000 bees at a Eugene apartment complex. Although ODA is taking actions to address pollinator protection, the frequent and continued occurrence of pesticide-related bee deaths indicates that current laws still fall woefully short of preventing these incidences. ODA’s Pesticide Program conducted an investigation that determined that Glass Tree Care and Spray Service, Inc. and its pesticide applicator violated Oregon’s pesticide control law through gross negligence. ODA is authorized to issue a civil penalty of up to $10,000 for violations that are the result of gross negligence, the maximum in this case issued to the company, a commercial pest control  operator based in Eugene. In addition, the applicator, James P. Mischkot, Jr., was issued a $6,000 civil penalty. When the incident in Eugene occurred, the trees were in full bloom and attracting pollinators.  In this case, ODA determined that the company and its applicator knew or should have known of this standard of […]

(Beyond Pesticides, November 3, 2014) A  state ban of neonicotinoid insecticides, which have become increasingly linked to the decline of honey bees and other pollinators worldwide, is under consideration  in Minnesota, making it the first state to move in this direction.  A revised version of an earlier review, “Scoping a Review of Neonicotinoid Use, Registration and Insect Pollinator Impacts in Minnesota,” published last  week, proposes a range of state action, including “restrictions on or cancellation of products,” The review  also calls for a “clarification of label provisions and enforcement designed to protect non-target organisms and the environment, targeted enforcement-related education, ”¦ suggesting research topics that would further the understanding of non-target impacts from neonicotinoids for policymakers, funding agencies, regulatory agencies, etc., and proposing other measures designed to minimize the impacts of pesticide use on human health and the environment.”  The earlier  review, issued in March, was heavily criticized for not including the option  of banning neonicotinoids. The state has already taken steps to address the  environmental crisis  linked to neonicotinoids. This year, Minnesota legislators passed a labeling law  that  will identify bee-friendly plants for  consumers. On a local level, Shorewood, MN became the first city in the state to pass […]

(Beyond Pesticides, October 21, 2014) Due in large part to the use of rodenticides in the cultivation of illegal marijuana grow operations, earlier this month the U.S. Fish and Wildlife Service (FWS) announced a proposal to list fishers, medium sized carnivores of the weasel family, as threatened under the Endangered Species Act. Fishers are the second species in the West that have been recognized by regulators as adversely affected  by illegal marijuana grow operations. Coho salmon have also been affected as a result of pesticide and fertilizer use, water withdrawals, and clear-cut logging that have silted, dried up, and polluted streams where the salmon run. Fishers, which are found throughout North America and have been part of the forests in Pacific states for thousands of years, have all but virtually disappeared in much of Washington, Oregon and California, according to FWS. Illegal marijuana grow operations have been a troubling source of wildlife deaths as growers often use “industrial-sized quantities of poison in forests to fend off rodents,” says Humboldt County District Supervisor Rex Bohn. A study published in PLOS One in 2012 found that 79% of fishers surrounding an illegal marijuana grow operation had been exposed to anticoagulant rodenticides. Fishers […]

(Beyond Pesticides, September 25, 2014) Last week, the Borough of Skagway, Alaska passed a comprehensive vegetative maintenance pesticide ordinance, joining a growing number of localities across the country in enacting restrictions that protect human health, wildlife, and the wider environment from the hazards associated with unnecessary pesticide use. Among a number of notable accomplishments, Skagway’s Ordinance 14-15 makes it the first municipality in Alaska to ban the use of bee-toxic neonicotinoids by government employees. However the new law goes further, prohibiting the sale and use of neonicotinoid-containing products on all public and private lands in the Borough of Skagway. The state of Alaska is one of seven states that affirms the right of a local jurisdiction  to restrict pesticide use throughout its jurisdiction by not adopting law that preempts localities. Skagway, Alaska’s Ordinance 14-15 also: Prohibits the sale and use of persistent herbicides (persistent according to the US Composting Council) on public and private property. Prohibits the use of restricted herbicides within 300 feet of any waterway. Creates a list of restricted pesticides (based in part upon the list of pesticides restricted in Takoma Park, Maryland). Although the ordinance establishes a waiver system by which restricted pesticides may be used, […]

(Beyond Pesticides, September 16, 2014) In light of President Obama’s Memorandum directing federal agencies to take action on pollinator declines, groups and members of Congress are calling on the U.S. Environmental Protection Agency (EPA) to take meaningful steps to save our bees. In a letter to EPA, U.S.Representatives Earl Blumenauer (D-OR) and John Conyers (D-MI) are urging the agency to follow the lead of the U.S. Fish and Wildlife Service (FWS) and revise pesticide regulations to protect pollinators from exposure to bee-toxic neonicointoids. >>Ask Your Representative to Join the Call: Urge Your Member of Congress to Sign-on to the Blumenauer-Conyers Letter to EPA! Pollinators, including honeybees, bumblebees, butterflies, and other insects, play a critical role in our agriculture systems. More than 70% of America’s food sources are pollinated by bees and the worldwide economic value of bee”pollinated crops is as high as $125 billion per year. Since 2006, however, beekeepers have lost more than 30% of their hives annually””a huge threat to the vitality of our farms. Pollinators are a critical driver of healthy, nutrient-dense foods. One in three bites of food depends on honey bees and other pollinators, and without them food prices are sure to rise and some […]

(Beyond Pesticides, September 12, 2014) A new U.S. Geological Survey (USGS) report finds that levels of pesticides continue to be a concern for aquatic life in many of the Nation’s rivers and streams in agricultural and urban areas. The study, which documents pesticide levels in U.S. waterways for two decades (1992-2011), finds pesticides and their breakdown products in U.S. streams more than 90 percent of the time. Known pesticide water contaminants, such as atrazine, metolachlor, and simazine, continue to be detected in streams more than 50 percent of the time, with fipronil being the pesticide most frequently found at levels of potential concern for aquatic organisms in urban streams. According to the USGS report, “An Overview Comparing Results from Two Decades of Monitoring for Pesticides in the Nation’s Streams and Rivers, 1992—2001 and 2002—2011,” featured in the journal, Environmental Science and Technology and part of the agency’s ongoing National Water-Quality Assessment Program, the proportion of streams with one or more pesticides that exceed an aquatic-life benchmark (or guideline) is similar between the two decades for streams and rivers draining agricultural and mixed-land use areas, but much greater during the 2002-2011 for streams draining urban areas. During both decades, one or […]
