Manganese Water Test

Manganese in Drinking Water: A Naturally Occurring Metal With Serious Neurological Consequences at Elevated Levels

Manganese is a naturally occurring metal found in rock, soil, and sediment formations across the United States. Like iron it dissolves into groundwater as it moves through these formations and can reach private wells at concentrations that pose real health risks. Also like iron it causes visible signs in your home that many people chalk up to general water quality issues without ever identifying the actual source. Dark brown or black staining on fixtures, sinks, and laundry, a bitter or metallic taste in drinking water, and black or brownish sediment in pipes and water heaters are all classic indicators of manganese in your water supply.

What makes manganese particularly important to test for is the severity of its health effects at elevated concentrations, which are more serious than most people realize. The EPA has set a health advisory level for manganese in drinking water at 0.3 milligrams per liter for adults and 0.1 milligrams per liter for infants. Long term exposure to manganese above these levels has been associated with neurological damage that resembles Parkinson’s disease, including tremors, muscle stiffness, and impaired motor control. Research has also linked elevated manganese exposure during pregnancy and early childhood to impaired brain development, reduced IQ, and behavioral and learning difficulties in children. These are not minor or speculative concerns. They are documented health outcomes from a contaminant that many well owners have never been advised to test for.

Manganese very commonly occurs alongside iron in well water since both metals share similar geological origins and behave similarly in groundwater. If your water has tested positive for elevated iron in the past or if you are experiencing the staining and taste issues associated with iron, testing for manganese at the same time is strongly advisable. The two contaminants often require similar treatment approaches including oxidizing filtration and greensand filters, but knowing the precise levels of both is essential for selecting and calibrating the right system for your specific water chemistry.

Manganese can also enter water from industrial and agricultural sources including certain fertilizers, fuel additives, and industrial discharges, making it a concern for well owners near these types of activities in addition to those in naturally manganese rich geological areas.

How It Works

Order your test and we will mail you a sample collection kit with easy to follow instructions. Collect a water sample from your tap and send it back to our in-house laboratory. Results are delivered within 1 to 3 business days from the date your sample arrives at our lab.

Understanding Your Results

Manganese results are measured against EPA health advisory levels for both adults and infants so you have a clear picture of your household’s specific risk. Every test includes a free consultation with one of our in-house water quality experts. If manganese is detected at concerning levels we will walk you through what that means for your household, whether iron testing is also advisable, and which treatment options are most effective for your situation including oxidizing filters, greensand filtration, and water softeners which can reduce manganese at lower concentration levels.

This test is recommended for private well owners experiencing dark brown or black staining on fixtures, sinks, or laundry, households noticing a bitter or metallic taste in their water, anyone whose water has previously tested positive for elevated iron since manganese frequently occurs alongside it, households with pregnant women, infants, or young children where neurological development concerns make early detection especially important, homebuyers purchasing a property with a private well, and well owners near industrial or agricultural activity where manganese may be entering groundwater from external sources.
