Manganese is the main contaminant present in Covington's groundwater that exceeds EPA health standards. The level is high enough to warrant attention, though it is not extremely severe.
Manganese comes from the rock layers beneath the city. The Valley and Ridge aquifers here contain minerals that release manganese as water moves through them over time. This is a natural process driven by the local geology rather than pollution from land use.
Groundwater in this county is moderately hard, driven by sulfate and moderate hardness minerals in the water. The rock formations underground naturally contain these minerals, which dissolve into the water as it flows through. Most wells in Covington show these characteristics to some degree.
Wells in Covington city commonly have manganese above EPA health standards. Manganese is a metal that comes from rocks and soil. Drinking water with too much manganese can affect how your brain and nerves work, especially in children and babies. Over time, exposure can cause problems with learning, memory, and movement.
Water in this county is moderately hard, which means you may see some mineral buildup on faucets and showerheads. Hard water can leave spots on dishes and glassware and make it harder to get soap to lather. The water may also have a slightly earthy or metallic taste. Over many years, moderately hard water can shorten the lifespan of water heaters and dishwashers.
We recommend testing your well water to find out what is actually in it, since every well is different and yours could have higher or lower levels than what is common in the county. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will tell you exactly what you are dealing with. Testing is the only way to know if treatment is needed for your family's health and comfort. If manganese is found, you have treatment options like oxidizing filters or water softeners that can remove it.
