… In Monterey County, 41% of the wells they sample have nitrate levels above the limit set by the state and the U.S. Environmental Protection Agency. That poses a health risk. Nitrates occur naturally in small amounts in water, plants and our bodies. But in excess, they can prevent red blood cells from carrying oxygen to tissues. In infants, this can cause potentially lethal blue baby syndrome. Nitrates have also been linked with birth defects, cancers and thyroid problems. The Central Coast Regional Water Board estimates that over 14,000 people within its boundaries rely on nitrate-polluted water.
