Uranium occurs naturally in some bedrock ground water; therefore deep bedrock wells are more susceptible to contamination than shallow wells. According to the DPH, Uranium in drinking water can be absorbed into the body and affect the kidneys over time. Bathing and showering with water that contains Uranium is not a concern. If uranium levels are higher than the EPA standard of 30 ug/l, the DPH recommends a point-of-use reverse osmosis system.
