A stream\u2019s ability to support these community structures can directly measure the health of waterways. The report assesses streamflow modifications and measures over 100 chemical constituents in water and streambed sediments. The report is a comprehensive assessment of the variety of factors that contribute to stream health declines, notably runoff from pesticides and contaminants.<\/p>\n<p>Daren Carlisle, Ph.D., an ecologist with the USGS and the lead author of the study, told <a href=\"http:\/\/www.michiganradio.org\/post\/scientists-diagnose-streams-trouble\"><i>Michigan Public Radio<\/i><\/a>, &#8220;If you were feeling sick and went to the doctor and all they did was took your temperature, you\u2019d say, &#8216;hey, wait a minute there\u2019s more to this than that.'&#8221; He continues, &#8220;What we\u2019re learning from this big assessment is just how many parts of the ecosystem need to be monitored and integrated together in order to really understand &#8216;what do we need to go fix now?'&#8221;<\/p>\n<p>The assessment reveals several areas that need fixing as stream health has been severely degraded throughout the nation. Indeed, only one in five streams in agricultural and urban areas are considered <i>relatively <\/i>healthy, and those are streams that tend to have little physical modifications and less runoff from roads and agricultural areas.<\/p>\n<p>As far as pesticides and contaminants are concerned, the report concludes that:<\/p>\n<ul>\n<li><b>Urban streams have pesticide concentrations that exceed one or more benchmarks at 83 percent of sites.<\/b> The most frequently detected pesticides in urban streams are <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=17\">chlorpyrifos<\/a> (a highly toxic organophosphate insecticides widely used in the US), <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=15\">carbaryl<\/a> (a carbamate insecticide and contact nerve toxin), and <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=24\">diazinon<\/a> (an organophosphate insecticide effecting the nervous system), all highly toxic pesticides that caused changes in macroinvertebrate communities.<\/li>\n<li><b>Agricultural streams have concentrations that exceed one or more benchmarks at 57 percent of sites.<\/b> The most frequently detected pesticides in agricultural stream are <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=17\">chlorpyrifos<\/a>, <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=94\">azinphos-methyl<\/a>, <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=7\">atrazine<\/a>, dichlorodiphenyldichloroethylene (a breakdown product of DDT), and <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/index.php?pesticideid=4\">alachlor<\/a>.<\/li>\n<li><b>The frequency of altered macroinvertebrate communities increased<\/b> from 20 to 42 percent as the potential toxicity of pesticide mixtures in stream water samples increased.

The report concludes that, \u00a0\u201cElevated concentrations of dissolved pesticide mixtures in stream water and contaminant mixtures in stream sediments have a high potential to diminish stream health across the Nation.\u201d<\/p>\n<p>While the report does not provide recommendations beyond the need to fill information gaps for understanding the ecological health of streams, the report does provide context for the interaction between human caused contaminants, pesticides, and streamflow modifications on the stream quality.<\/p>\n<p>Previous USGS <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=1493\">reports<\/a> have documented pesticides and fertilizers in U.S. streams and <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=1010\">drinking water<\/a>. Herbicides like <a href=\"https:\/\/www.beyondpesticides.org\/pesticides\/factsheets\/Atrazine.pdf\" target=\"_blank\">atrazine<\/a>, metalachlor, and <a href=\"https:\/\/www.beyondpesticides.org\/gateway\/pesticide\/simazine.htm\">simizine<\/a> are among those often found in surface waters of 186 rivers and streams sampled by USGS since the early 1990s, and are highly correlated with the presence of upstream wastewater sources or upstream agricultural and urban land use. Recently, USGS released a <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=7394\">national assessment<\/a> that shows the distribution and trends of pesticide use from 1992-2009, providing visible evidence that contamination of pesticides in our nation\u2019s water is clearly a continuing threat.<\/p>\n<p>Meanwhile, regulations that protect U.S. waterways from chemical contamination, including contamination from pesticides, have been attacked by industry groups and Congress. Under the <em>Clean Water Act (CWA)<\/em>,  \u00a0pesticide users who spray over waterways must have a National Pollutant Discharge Elimination System (NPDES) permit. This requirement  \u00a0follows a 2009 federal appeals court ruling in <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=1104\"><i>National Cotton Council v. EPA<\/i><\/a>, and simply lets authorities know what is sprayed and when it is sprayed, so that the public may know what chemicals are used in their waterways.  \u00a0However, since the<a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=6254\"> enaction of the NPDES permit requirement<\/a>, in 2011, <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=6002\">several pieces of legislation <\/a>have been introduced in Congress that would eliminate these regulations.<\/p>\n<p>In May, the <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=10378\">Sensible Environmental Protection Act<\/a> was introduced by Senator Kay Hagan (D-NC), with support from Larry Wooten, president of the North Carolina Farm Bureau, to eliminate <i>NPDES <\/i>permits. The claim from industry lobby groups is often that these permits are burdensome on farmers and costly, though fees can be as low as $25 for the permit, and states that oversee the permitting program stand to collect this revenue.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/11259","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=11259"}],"version-history":[{"count":13,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/11259\/revisions"}],"predecessor-version":[{"id":11271,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/11259\/revisions\/11271"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=11259"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=11259"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=11259"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
