Well Water in Sumter County: What to Test and Why

Groundwater in Sumter County contains manganese, iron, and nitrate at levels that exceed EPA health standards. These contaminants are present at concerning concentrations that well owners should address.

The Southeastern Coastal Plain has sandy and clay layers that naturally contain iron and manganese minerals. When water moves through these rocks, it dissolves these metals. Nitrate comes from agricultural activities and septic systems in the area, seeping down into the groundwater.

Groundwater in this county is soft with low iron and sodium levels overall, but manganese and nitrate are the minerals of concern here. These metals concentrate in the groundwater as it travels through the sand and clay layers underground. Manganese and nitrate show up in wells across the county at varying levels.

Wells in Sumter County have been found with iron, manganese, and nitrate at levels that exceed EPA health standards. Iron and manganese can cause problems with your blood and nervous system if you drink water with too much of them over time. Nitrate is especially concerning for babies and young children, as it can prevent their blood from carrying oxygen properly. Testing your well is the first step to understanding what you're dealing with.

The good news is that the minerals in county wells are not causing the typical staining and scaling problems seen in harder water areas. Your water should not leave orange or brown stains on fixtures or cause buildup in pipes and appliances. You likely won't experience the taste or odor issues that come with high mineral content. The water quality issues here are about what you cannot see, not what you can.

We recommend getting a comprehensive water test for your well, since multiple contaminants are showing up in the county. Every well is different, and your water could have higher or lower levels than what we see on average. Testing is the only way to know exactly what is in your well so you can treat it properly. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will tell you what you need to do next.
