One of the big challenges facing the globe in the next century will be access to clean water.
In America, federal agriculture policies are putting drinking water used by millions of people at risk. Perverse incentives such as farm subsidies and ethanol mandates have ushered in an era of fencerow-to-fencerow planting of chemical-intensive commodity crops, even as funding to protect water sources has been repeatedly slashed.
The result is that water running off poorly managed fields that have been treated with chemical fertilizers and manure is loaded with nitrogen and phosphorus, two potent pollutants that set off a cascade of harmful consequences.
Troubled Waters, a new Environmental Working Group report released on April 12, examines the water pollution caused by farm runoff in the upper Midwest and demonstrates that treating the problem after the fact is increasingly expensive, difficult and, if current trends continue, ultimately unsustainable. Because most farm operations are exempt from the requirements of the federal Clean Water Act and states have little authority to compel farmers to control water contamination, the burden of cleaning up agricultural pollution in drinking water falls mostly on municipal treatment systems – and the taxpayers who pay for them.
