Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron. Iron is one of the most common elements in the Earth’s crust and dissolves in underground water. This carries the iron into the water supply as ground water seeps into aquifers. Iron can be found in drinking water as ferrous iron which is soluble and ferric iron which is insoluble. ----- State and Vater Use Iron Criteria Values Pennsylvania All All 38 1.5 mg/1 0.3 mg/1 as total iron as dissolved iron General water quality criteria narrative: Water shall not contain substances attributable to point or nonpoint source waste discharges in concentration or amounts sufficient to be inimical or harmful to the water uses to be protected or to human, animal, plant, or aquatic life. Hard = 7-10.5 GPG (total grains x 17.1 equals ppm) Extremely Hard Water = 10.5+ GPG (total grains x 17.1 equals ppm) WARNING: Beware of companies that tell you that each PPM of iron is equal to 4-5 Grains per gallon of hardness.
