Mercury is a liquid metal found in natural deposits such as ores containing other elements. The major sources of mercury in drinking water are erosion of natural deposits; discharge from refineries and factories; runoff from landfills; and runoff from croplands.
Some people who drink water containing mercury well in excess of the maximum contaminant level (MCL) for many years could experience kidney damage.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Mercury levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Mercury levels were detected in your water sample but do not exceed the maximum contaminant level.
