Why This Happens Here

Groundwater in Forsyth County contains iron, chloride, and arsenic. Chloride and iron are present at levels that exceed EPA health standards, so well owners should test their water and consider treatment options.

These contaminants come from the rock layers beneath the county. The Early Mesozoic basin aquifers here are different from the hard crystalline rock found in neighboring counties--these softer rock layers release iron and salt naturally into the water as it flows through them.

Groundwater in this county is soft, with low iron and low mineral content overall. The water picks up small amounts of salt from the rock as it moves underground, but the rock composition here does not create the hard water problems seen in limestone areas nearby. Most wells in Forsyth County show this same soft water character.

What This Means for You

Wells in Forsyth County show chloride and iron at levels that exceed EPA health standards. Chloride at elevated levels can raise blood pressure in some people, especially those with heart or kidney problems. Iron above safe drinking water limits can cause organ damage over time, particularly affecting the liver and heart.

Forsyth County wells generally have soft water, which is good news for scale buildup and appliance lifespan. However, elevated iron in county wells can leave orange or brown stains on fixtures, laundry, and dishes. You may notice a metallic taste in the water or rust-colored discoloration when water sits.

Every well is different, and yours could have higher or lower levels than what is common in the county. We recommend a comprehensive water panel to know exactly what is in your well so you can treat it properly. Testing costs between $200 and $400 for a full metals and minerals panel. Iron and chloride removal systems are available depending on what your test shows.
