WASHINGTON - Most of the nation's rivers and streams — and the fish in

them — are contaminated with pesticides linked to cancer, birth defects

and neurological disorders, but not at levels that can harm humans.

 

Pesticides were found in almost all U.S. rivers and streams between

1992 and 2001, says a study released Friday by the U.S. Geological

Survey, although most drinking water supplies haven't been affected.

 

" While the use of pesticides has resulted in a wide range of benefits

to control weeds, insects and other pests, including increased food

production and reduction of insect-borne disease, their use also raises

questions about possible effects on the environment, including water

quality, " said Robert Hirsch, the USGS associate director for water.

 

Pesticides were seldom found at concentrations likely to affect people,

and they were less common in groundwater. But they were found in most

fish.

 

Most frequently detected in agricultural streams were three herbicides

used mainly on farms: atrazine, metolachlor and cyanazine. Just last

week, the Environmental Protection Agency settled a 2003 lawsuit

brought by the Natural Resources Defense Council, forcing the

government to assess whether atrazine threatens the survival of

endangered Chesapeake Bay sea turtles, endangered Texas salamanders and

16 other aquatic species.

 

Three other herbicides used commonly in cities — simazine, prometon and

tebuthiuron — showed up more often in urban streams.

 

The USGS looked for 100 pesticides, and found 40 of them had a

widespread presence in streams and sediment in both urban and

agricultural areas, at concentrations that could affect aquatic life or

fish-eating wildlife. The pesticides showed up more than 90 percent of

the time in the fish tissue found in agricultural, urban and mixed

land-use areas.

 

In each of the streams the USGS studied, at least one pesticide was

detected. In about 19 of every 20 streams with agricultural, urban or

mixed land-use watersheds, pesticide compounds were found at nearly all

times of the year. The most frequent occurrence was in shallow

groundwater beneath agricultural and urban areas, where more than half

the wells contained one or more pesticide compounds.

 

Jay Feldman, executive director of Beyond Pesticides, a national

research and advocacy group, said the data surrounding the nation's

reliance on about 1 billion pounds of pesticides a year " shows an

urgent need to strengthen policies at all levels of government and

curtail pesticide use. "

 

The USGS report is based on an analysis of data from 51 major river

basins and aquifer systems nationally, and a study of an aquifer system

that runs through eight states from South Dakota to Texas, east of the

Rocky Mountains.

 

It found that concentrations of individual pesticides nearly always

complied with the EPA's drinking-water standards, though no water

samples from streams were taken at drinking-water intakes. The EPA also

is responsible for reviewing pesticides, based on pesticide-makers'

tests that can cost tens of millions of dollars. It typically takes up

to a decade to study each one before it can reach the marketplace,

according to industry figures.

 

But simply detecting the presence of a pesticide does not always mean

there is reason for concern, said Jay Vroom, president of CropLife

America, which represents pesticide developers and manufacturers. He

emphasized that the use of pesticides by farmers, ranchers and others

is strictly regulated by federal and state laws.

 

" Water quality is of paramount importance to us, " he said. " And the

USGS report correctly recognizes that the large majority of pesticide

detections in streams and groundwater were trace amounts, far below

scientifically based minimum levels set for protecting human health and

the environment. "

yeah well I bet part of that stuff was not pesticides but rather chemtrail poisons.

I know damn good and well that there is no one spraying or pouring pesticides into the top of the water chains in the high rockies... but I see chemtrails over them all the time.
