(Beyond Pesticides, March 05, 2015) A federal audit has concluded that acceptable federal inspections at pesticide-producing establishments have not been conducted in North Dakota, possibly endangering the public and the environment. The U.S. Environmental Protection Agency’s (EPA) independent Office of Inspector General (OIG) issued a report last week that finds the state lacks a state inspector with qualifications equivalent to a federal inspector who can conduct inspections on EPA’s behalf. As a result, North Dakota facilities that produce or handle pesticides have not been federally inspected for 14 years, and that about 1,300 pesticide imports that have come through the state since 2011 have not undergone federal inspections. “Without such inspections, residents in other states and locations in the United States, in addition to North Dakota, could be at risk,” according to the report signed by EPA Inspector General Arthur A. Elkins Jr. Staff at EPA Region 8 stated that inspections authorized under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) have not been conducted because North Dakota officials do not want federal inspections in their state. FIFRA (Section 7) gives EPA inspection authority and enables the agency to take enforcement actions against facilities that are not in compliance with […]

(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, […]

(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 24, 2015) According to recent reports from local California news outlets, Honey Bees are in Short Supply In Central Valley, with the risk that consumers across the United States will be seeing higher prices on fruits, nuts, and vegetables this year as a consequence of declining honey bee populations. The ongoing pollinator crisis has resulted in greater than 30% of managed bee colonies dying off each winter since 2006, an unsustainable rate that will inevitably impact the pocketbooks of consumers in the U.S. and may even ultimately result in global malnutrition. But that doesn’t have to be the outcome. As Beyond Pesticides continues to remind concerned residents, although there are a number of hazards affecting honey bee populations, this crisis is No Longer a Big Mystery. The scientific evidence shows that a class of toxic, persistent, systemic chemicals called neonicotinoids present immense risks to honey bees and other pollinator species. Twenty-nine scientists spanning multiple disciplines analyzed over 800 peer-reviewed papers on the subject came to a similar conclusion. “The assessment found that both individuals and populations can be adversely affected by low or acute exposure making them highly vulnerable. Pollinators exposed to contaminated pollen, nectar and water […]

(Beyond Pesticides, February 23, 2015) A Hawaii state House agriculture committee rejected a bill Thursday that sought to impose buffer zones for large agricultural companies that spray restricted-use pesticides near schools and other sensitive areas. The proposal, House Bill 1514, introduced by Rep. Chris Lea, stemmed from concerns about  the impact of genetically-engineered (GE) farming and its inherent dependency on increasing  pesticide use. The measure sought  to require companies’  disclosure of the pesticides used and the volume of use. The bill had strong support from the Hawaii chapter of the national nonprofit Center for Food Safety (CFS), as well as a strong backing from neighbor island residents. Maui, Kauai, and the Big Island have all passed laws recently to regulate the seed industry, but a federal  district  court judge  has ruled  that Hawaii counties do not have that power. Industry has been especially effective in obstructing the bill. CFS’ Hawaii director, Ashley Lukens, said after Thursday’s hearing that she was frustrated by the limited amount of time advocates were given to testify. “It was clear from the very beginning that the hearing was intended to allow the industry to reiterate their talking points,” she said. Not surprisingly, companies (like Monsanto) […]

(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 11, 2015) In 2008, France announced it would voluntarily cut pesticide use by 50 percent by 2018, and emerged as the European leader in  reducing pesticide dependency. With its plan faltering, the European Union’s (EU) biggest agricultural producer and pesticide user has announced the expansion of  a network of pioneer farms experimenting with alternative techniques and mandated reductions in pesticide sales as it  delays its target reduction until 2025. The French government has pushed back to 2025 the timeline for halving pesticide use and added an intermediate target of a 25 percent fall by 2020, Agriculture Minister Stephane Le Foll said. The  2018 target was slated as voluntary, but pesticide use has actually increased, in part due to poor weather, according to French officials. As the EU’s top agricultural producer, France is trying to become less dependent on pesticides, which are known to pose various health and environmental risks. The targets for pesticide reduction remain mostly non-binding on farmers, but Minister Le Foll said his revamped plan would encourage a change in practices by expanding their focus on  alternative techniques. The minister notes that farmers need training  in best practices to replace the massive use of pesticides […]

(Beyond Pesticides, February 5, 2015) A brewing  battle in the European Union (EU) over removing from the market  Endocrine Disrupting Chemicals (EDC)s has  heated up. An investigative report in  The Guardian  reveals that a European Union (EU) scientific paper, prepared to assist in the development of new mandatory EDC risk assessment standards, was never made public. According to the report, EU Commission sources say the release of the paper was quashed as a result of chemical industry pressure and political influence. At the core of the debate lies two EU regulations, one concerning biocidal products (EU 528/2012) and the second on “plant pest protectants” (EU 1107/2009). Both of these regulations required the EU Commission to produce draft measures concerning specific scientific criteria for the determination of endocrine disrupting properties by December 14, 2013. Under the regulations, chemicals within the biocidal and plant pest protectant categories that are  categorized as having endocrine disrupting properties that may cause adverse effects in humans would be prohibited from use in the market place. As noted in the purpose and subject matter of the biocidal regulations, “The purpose of [the] Regulation is to improve the functioning of the internal market through the harmonization of the […]

(Beyond Pesticides, January 27, 2015) In  evaluating a farmworker poisoning incident in Washington State last year, a Centers for Disease Control and Prevention (CDC) report identifies “at least three potential occupational hazards in agriculture: off-target pesticide drift, toxicity of some recently marketed pesticides, and a gap in worker notification requirements.” The report recounts the poisoning in  April 2014 of 20 farmworkers at a Washington State cherry farm who were trellising cherry tree branches when a new pesticide mixture being applied to a neighboring pear orchard drifted on to their work site, causing acute illness within minutes. Sixteen farmworkers sought medical treatment for symptoms ranging from headache and eye irritation to gastrointestinal disorders and respiratory problems. Half of the affected workers had symptoms which persisted over two weeks. The workers were not notified of the planned pesticide application at the neighboring orchard. The  CDC report on the incident, authored by Geoffrey M. Calvert, MD (National Institute for Occupational Safety and Health), Luis Rodriguez, and Joanne Bonnar Prado, MPH  (Washington  State Department of Health), cites 31% of acute pesticide related illnesses for farmworkers between 2005 and 2012 occurring as a result of off-target drift from a neighboring farm. In the April incident, […]

(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 22, 2015) The Iowa Farmers Union filed  a petition yesterday with  the Iowa Department of Agriculture and Land Stewardship (IDALS) for rulemaking to improve pesticide drift incident responses, penalties, and support to farmers harmed by pesticide drift. “Pesticide  drift from nearby fields is a very real problem for farmers in Iowa,” says Jordan Scheibel, a diversified vegetable farmer from Grinnell, Iowa. “Not only can pesticide drift delay or cause a farm to lose its organic certification, it results in products that farmers – certified organic or not – may not be able to sell legally, safely, or in good conscience, and it exposes the farmers and their workers to potentially harmful pesticides.” Pesticide drift is an inevitable problem in chemical-intensive pest management strategies that rely on spray and dust pesticide formulations.There are essentially two types of drift: particle drift (off-target movement during application) and vapor drift (off-target movement when a pesticide evaporates from a sprayed surface), also known as volatilization. Both forms of drift present serious problems to unaware farmers and surrounding communities. IDAL, which oversees pesticide application in the state, collects information about the location of farmers with sensitive crops, such as grapes, certain vegetables, organic […]

(Beyond Pesticides, January 16, 2015) The California Department of Pesticide Regulation (CDPR) announced Wednesday that it is implementing the country’s strictest limits on chloropicrin, a chemical injected into the soil where strawberries, raspberries, almonds, and other crops are grown. The soil fumigant has been linked to a litany of health effects, such as respiratory ailments, skin irritation, and headaches, due to exposure to drift in surrounding areas over recent years. The new rules set up wider buffer zones of up to 100 feet around fields where the pesticide is applied. Growers will be restricted to fumigating 40 acres a day unless they use stronger tarps to prevent pesticide drift. Growers are also required to give the state 48 hours notice before fumigating and notify surrounding homes and businesses in Spanish and English. Chloropicrin is used to control soil pathogens, nematodes, and certain weeds, and can be used alone or in combination with another fumigant, either 1,3-dichloropropene (1,3-D) or methyl bromide, both of which have also been shown to be toxic to human health and potent environmental contaminants. The new chloropicrin restrictions are timely; a 2011 report found that pesticide use rose in 2010 after a four-year decline. The pesticides with […]

(Beyond Pesticides, January 14, 2015)””More than 100 businesses, including Clif Bar, Nature’s Path, Organic Valley and Stonyfield, sent a letter to the White House yesterday urging it to immediately suspend pesticides linked to global bee declines in order to protect the nation’s food supply, environment and economy. The businesses, members of the American Sustainable Business Council (ASBC) and Green America’s Green Business Network, voiced concerns about the U.S. Environmental Protection Agency (EPA)’s delays in restricting neonicotinoids, the world’s most widely-used insecticides. Many of the 118 businesses that signed the letter sell products with ingredients or inputs that are dependent on pollination from bees and other pollinators, including fruits, vegetables, nuts, seeds, fiber (such as cotton) and hay (including alfalfa grown to feed livestock). The businesses call on the EPA to immediately suspend the registrations of neonicotinoids for agricultural uses, including seed treatments, as well as cosmetic and other unnecessary uses pending the results of pesticide re-evaluation. They also called for increased investments in green, fair and cutting-edge alternatives to neonicotinoids that support a prosperous and sustainable agricultural system. “We are very concerned about the continued and unsustainable losses of bees and other essential pollinators and what effects this will have […]

(Beyond Pesticides, January 09, 2015) New closed-door international trade agreement proposals between the U.S. and EU could weaken pesticide standards and threaten the U.S. organic food industry. Set forth by European and U.S. trade associations, the proposals were met  with strong disapproval by numerous non-governmental organizations (NGO) and non-profits. Beyond Pesticides and over a hundred other European and U.S.-based organizations signed on to a letter in July 2014 calling for increased transparency of negotiating proposals and  the exclusion of chemical regulations from the entire scope of the prospective Transatlantic Trade and Investment Partnership (TTIP). The proposals are recommended by the trade associations CropLife America and the European Crop Protection Association (ECPA) —which represent major agricultural chemical manufactures like Bayer CropScience, Dow AgroSciences, and DuPont Crop Protection— with claims that the policy would help reduce or get rid of trade barriers and help promote regulatory cooperation and achieve the goals of the TTIP. According to a new Center for International Environmental Law (CIEL) report, however, these proposals push for anemic pesticide residue limits in the EU, which are currently some of the strongest ones in existence and have influenced more stringent standards around the world, including the U.S. The groups recommend […]

(Beyond Pesticides, January 5, 2015) Hawai’i County plans to appeal a federal judge’s ruling invalidating a 2013 county law restricting genetically engineered (GE) crops on the island. The County Council voted 5-4 in December to appeal the ruling after the judge ruled last November that Hawai’i County cannot enforce a law restricting genetically engineered crops because it is preempted by state law. The ruling follows a similar federal court decision in August 2014 that overrules a Kauai ordinance requiring annual reporting of genetically engineered organisms. U.S. Magistrate Judge Barry Kurren’s order is similar to his earlier decision invalidating Kauai County’s law on pesticides and GE crops. Judge Kurren invalidated the county law, Hawai`i County Ordinance 13-121, in a Nov. 27, 2014 order, saying state law preempts county law on the issue. He said lawmakers intended the state to have broad oversight of agricultural issues in Hawai’i. The November 2014 decision concludes that state “preemption” of the county ordinance is implied by state plant laws, despite the fact none of them mention GE crops or were intended to regulate them. The court refused a request to send the state law question to the Hawai’i Supreme Court  for a  decision. Finally, the […]

(Beyond Pesticides, November 13, 2014) In an investigative report, Dark Side of the Strawberry, Center for Investigative Reporting provides a sordid story and analysis of  the rise of one of California’s most prized crops, strawberries, while state  regulators  ignored public health and environmental risks associated with the pesticides used in their production. The report focuses on a pesticide called 1,3-Dichloropropene (1,3-D), a restricted use soil  fumigant used to kill nematodes, insects, and weeds, that has strong links to cancer and other serious health issues. The use of the chemical in the production of strawberries came into prominence with the forced reduction of another fumigant, methyl bromide. As the report chronicles, besides the many other issues associated with methyl bromide, scientists began to become concerned sometime in 1970s that escaped methyl bromide gas had serious effects on the ozone and was blamed for between 5 and 10 percent of ozone depletion. With the signing of Montreal Protocol in 1987, a treaty that President Reagan signed on behalf of the U.S., methyl bromide became the only pesticide to be banned by treaty, a ban meant to be in full effect by 2005. While the European Union and other industrialized nations followed through […]

(Beyond Pesticides, November 7, 2014) Environmental organizations are calling on the Canadian government to  reject the approval of yet another bee-killing pesticide called flupyradifurone. According to Health Canada’s Pest Management Regulatory Agency (PMRA) —responsible for regulating pesticides in Canada— the new pesticide exhibits systemic behavior and “may pose a risk to bees, non-target beneficial arthropods, and freshwater and saltwater invertebrates when used for foliar application.” Additionally, the pesticide “may pose a risk to birds and small wild mammals when used for soybean seed treatment.”  Environmentalists say approval of  flupyradifurone would be irresponsible of PMRA because it would allow yet another chemical with a high potential hazard to bee health into the environment. Environmental groups, including Sierra Club Canada Foundation, David Suzuki Foundation, Pollination Canada, National Farmers Union, Friends of the Earth, and Canadian Association of Physicians for the Environment, have been vocal in expressing their concern about flupyradifurone: “Health Canada has admitted the use of neonicotinoid pesticides threatens bees and other pollinators and has promised a review, but meanwhile wants to open the door to its chemical cousin. Is the government taking the threat of systemic pesticides seriously?” said Lisa Gue, a researcher and analyst at David Suzuki Foundation. Karen […]

(Beyond Pesticides, October 2, 2014) California state pesticide regulators are looking to curtail the use of chlorpyrifos, one of the most widely used insecticides on the market, due to concerns that it poses a threat to human health and the environment. At the same time, environmental groups are suing the U.S. Environmental Protection Agency (EPA) because of the agency’s continued refusal to fully address a 2007 petition by the groups calling for a ban on the neurotoxic chemical. EPA in 2000 orchestrated a voluntary cancellation by DowAgroSciences of  most residential uses of chlorpyrifos (although uses with major exposure routes continue),  while virtually all agricultural uses remain in use, except tomatoes. The California Department of Pesticide Regulation (DPR), a branch of the California Environmental Protection Agency that regulates the sale and use of pesticides, announced last week that it is  proposing to make  ‘restrictive use’  all pesticide products containing the organophosphate  insecticide chlorpyrifos.  If the proposed regulation passes, this would mean that only trained and licensed professionals who have a permit from a local county agricultural commissioner (CAC) would be able to use these products. The CAC would also have the ability to place additional conditions on use via the permit. […]

(Beyond Pesticides, September 29, 2014) Last week, the Seattle City Council voted unanimously to prohibit the use of neonicotinoid pesticides on land owned or maintained by the city. Neonicotinoid insecticides have been linked to colony collapse disorder (CCD) and declining bee health that has resulted in a near devastating decline in viable managed beehives, which are critical to pollination of one-third of the nation’s food supply. Seattle is the largest city thus far to enact such a ban to protect pollinators in the absence of federal regulation. Other localities taking action include  Skagway, Alaska, Eugene, Oregon and Spokane, Washington and dozens of other jurisdictions that have adopted organic land management practices or pesticide bans on   public land, private land, parks, schools, and other land under their authority. Resolution 31548, adopted and expected to be signed by Mayor Ed M.urray, states that the City of Seattle shall ban the purchase and use of neonicotinoids on city-owned property and calls for a national moratorium on the use of the toxic pesticides, urging the White House Task Force, U.S. Environmental Protection Agency, and Congress to suspend the registration of neonicotinoids. Along with encouraging federal action, the resolution asks retailers within Seattle to […]

(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 […]
