I don’t know what should be more concerning, the fact that the EPA has decided it should regulate toxic substances in tap water, or that the move is “reversing a Bush-era decision” according to the LA Times.
In the LA Times article:
The Environmental Protection Agency took steps Wednesday to curb toxic substances in drinking water, including perchlorate, a chemical thought to threaten the thyroid gland that has contaminated hundreds of public water wells, mostly in California.The agency also moved to set standards for 16 other substances that can invade water supplies and impair human health.
Research by the Food and Drug Administration, among others, found perchlorate contamination in food and water in 45 states, and a small study in the Boston area found perchlorate in the breast milk of nursing mothers.
In the past, industrial users of perchlorate commonly dumped it into unlined pits, from which it leached into groundwater, scientists say. The most heavily affected areas have been Los Angeles, Riverside, San Bernardino, Orange and Sacramento counties. California law requires that perchlorate levels be below 6 parts per billion. It was unclear what the federal limit would be. Late last year, a contaminated well in Barstow had a level of 100 parts per billion.
Sounds serious, right? Well not that serious, as the process of regulating perchlorate levels could take up to two years. Drink up that breast milk Boston babies.
