Well Water in Crisp County: What to Test and Why

Groundwater in Crisp County contains manganese, iron, and nitrate at levels high enough to exceed EPA health standards. These contaminants are present at concerning levels that well owners should monitor and address.

The source of these contaminants comes from the local rock and soil. Iron and manganese occur naturally in the sandy and clayey layers of the Southeastern Coastal Plain aquifer system. Nitrate often enters groundwater through agricultural practices and septic systems in this farming region, where it seeps down through the soil into the water below.

Groundwater in Crisp County is moderately hard, driven mainly by dissolved minerals like calcium and magnesium that come from the sedimentary rocks and clay layers in the aquifer system. These minerals dissolve slowly as water moves through the ground over time. Moderate hardness is common across many wells in the county, though individual wells can vary.

Wells in Crisp County have been found to contain iron, manganese, and nitrate at levels above EPA health standards. Iron and manganese are metals that can build up in your body over time and cause problems with your nervous system and bones. Nitrate is a chemical that can be especially harmful to babies and pregnant women, interfering with how their blood carries oxygen. Testing your well is the only way to know if your water has these contaminants.

The moderate hardness in county wells can cause some everyday problems around your home. You might notice orange or brown staining on sinks, toilets, and laundry from iron in the water. Buildup of minerals can form scale inside pipes and on fixtures, and you may see cloudiness in your water. Hard water can also shorten the life of water heaters and dishwashers over time.

We recommend testing your well with a comprehensive panel to check for metals, minerals, and bacteria, since multiple contaminants have been found in this county. Testing costs between two hundred and four hundred dollars and is the only way to know what is actually in your water so you can treat it properly. Your well may have higher or lower levels than what is common in the county. Treatment options like iron filters or water softeners can help, depending on what testing shows.
