An estimated 370,000 Californians rely on drinking water that may contain high levels of arsenic, nitrate or hexavalent chromium, and contaminated drinking water disproportionately impact communities of color in the state, finds a new analysis led by researchers at the University of California, Berkeley, and the University of California, Los Angeles.
Because this study is limited to three common contaminants, results likely underestimate the actual number of Californians impacted by … [more…]

Iowa’s work to clean polluted waterways is so slow it will take as much as 22,000 years to meet some of the goals in the state’s voluntary plan, the Iowa Environmental Council reported.

Cleverley had learned that each spring, as the soil warmed and moistened, it released nitrogen—both naturally occurring and left over from the last application of synthetic … [more…]

Scientists have known for decades that drinking water contaminated by fertilizer nitrates can pose a threat to infants by undermining the ability of their blood to carry oxygen. The condition, known as ‘blue baby syndrome,” led federal regulators to impose an environmental standard of no more than 10 parts per million, or ppm, for nitrates in public water supplies. Recently, though, some evidence suggests that long-term ingestion
