Ohio—Lake Erie，the fourth largest lake of North America’s five Great supplies fresh drinking water to an estimated 11 million people in Ohio，Michigan and South Ontario，Canada.

Yet sometimes pollution，both from industrial waste and farm-chemical runoff，leaves large areas of the lake covered in half-meter-thick layers of green slime(黏液)．Scientists blame a lot of chemicals entering the water，which has caused pollution.

To find out where these chemicals come from，the Ohio Department of Natural Resources has been studying data from its network of 14 water-quality monitoring stations installed along the rivers that flow into the Lake Erie basin.

At one point，water from the small stream is diverted into pipe where it is pumped into the testing station.

“We’ll have a sample a day，year round so that really pins down what the chemistry is like，”says Dave Baker of Ohio’s Heidelberg University，who took charge of the monitoring stations for the Department of Natural Resources.

The U．S.Environmental Protection Agency，the federal government’s pollution watchdog，requires point sources，such as factories，to monitor and report their discharges(排出物)．So Baker is looking for where the other sources of pollution come from.

“If there are problems in Lake Erie，we want to know where it’s coming from and make sure we’re putting resources to solve the problem properly，”Baker says.“It’s stations like this that help do that.”

In this case，a primary source of the pollution turns out to be chemical fertilizers that wash off farmland during rainstorms.

Because farmers and ranchers believe fertilizers are essential to high crop yields，they would like to use them.However，the USDA’s Natural Resource Conservation Service isn’t asking them to abandon farm chemicals，but rather to use them more sparingly(慎用地) so that they don’t run off the land when it rains.

Another technique for reducing farm chemical pollution of Lake Erie is cover-crop farming.After the harvest，farmers plant a second quick-growing crop to reduce erosion.The
