Farming Communities Facing Crisis over Nitrate Pollution, Study Says

By Stett Holbrook
Nitrate contamination in groundwater from fertilizer and animal manure is severe and getting worse for hundreds of thousands of residents in California's Central Valley farming communities, according to a study released Tuesday by researchers at the University of California, Davis.

Nearly 10 percent of the 2.6 million people living in the Tulare Lake Basin and Salinas Valley might be drinking nitrate-contaminated water, researchers found. And if nothing is done to stem the problem, the report warns, nearly 80 percent of residents could be at risk of health and financial problems by 2050.

High nitrate levels in drinking water have been linked to thyroid cancer, skin rashes, hair loss, birth defects and "blue baby syndrome," a potentially fatal blood disorder in infants.

The report is the most comprehensive assessment so far of nitrate contamination in California's agricultural areas.

The problem is much, much, much worse than we thought," said Angela Schroeter, agricultural regulatory program manager for the Central Coast Regional Water Quality Control Board, a state water agency.

Oceans on Brink of Catastrophe: Why We Must Stop Global Warming & Industrial Pollution

The world's oceans are faced with an unprecedented loss of species comparable to the great mass extinctions of prehistory, a major report suggests today. The seas are degenerating far faster than anyone has predicted, the report says, because of the cumulative impact of a number of severe individual stresses, ranging from climate warming and sea-water acidification, to widespread chemical pollution and gross overfishing.

The coming together of these factors is now threatening the marine environment with a catastrophe "unprecedented in human history", according to the report, from a panel of leading marine scientists brought together in Oxford earlier this year by the International Programme on the State of the Ocean (IPSO) and the International Union for the Conservation of Nature (IUCN).
