Officials at Mammoth Community Water District point to the latest water quality report for the Mammoth water supply on their website and explained to customers that dangerous chemicals have been a problem in many areas of the nation’s water supply but not in Mammoth Lakes.

In a press release, District officials say that the public was recently reminded of the potential hazards of chromium-6 in the nation’s water supply by a PBS News Hour segment called “Toxic Clout.” Officials also point out that the movie, “Erin Brokovich” brought to light the dangers of chromium-6.

Mammoth Water District officials say that they want customers to know that all of the water supply sources in the community have been specifically checked for chromium-6 and no detectable levels have ever been found.

Officials say that California has the strictest maximum contaminant levels in the nation for total chromium. Chromium-6, they point out, is toxic and known to cause cancer when inhaled and possibly when ingested.

Mammoth Water District monitors surface water supplies annually and groundwater production wells on a three-year schedule. Check out the latest report at www.mcwd.dst.ca.us.
