Source of Mercury in Water: Mercury (Hg) is a metallic element that occurs naturally. Mercury can enter the food chain through fish and comes primarily from industrial chemical manufacturing waste or from the leaching of coal ash. Mercury in water has been found in groundwater and wells where it is present in mineral deposits or where a volcano has been active. Since mercury is also used in the production of electrical products, its presence may also be because of industrial pollution. Landfills with batteries or other electrical parts improperly disposed of may also introduce mercury into groundwater through runoff. The MCL that water municipalities must test for is 0.002 mg/L.
Symptoms of Mercury: The health effects of mercury are severe. Studies have shown that exposure to high levels mercury in water can cause neurological and renal problems. It can also cause vomiting and diarrhea.
Filtration Solutions for Mercury: Effective mercury water treatment includes activated carbon filtration as a very effective way to remove mercury in drinking water. Reverse osmosis water systems will remove 95-97% of mercury in water.
