Copper in Florida well water
In Florida, <1% of 14,171 tested private well samples exceeded the EPA limit for copper (1.3 mg/L).
Copper leaches from pipes when water is acidic. Above 1.3 mg/L it causes stomach upset, and long-term exposure can harm the liver and kidneys. Blue-green stains on fixtures are the giveaway.
