Chloride, fluoride, and hardness are present in Dooly County groundwater. None of these contaminants exceed EPA health standards, so the levels here are low.
These minerals come from the sand and clay layers beneath the county. Water naturally dissolves salts and minerals as it moves through these rock layers over time. The sandy aquifer that supplies wells here does not block these dissolved minerals, so they remain in the water.
Groundwater in this county is moderately hard, driven by calcium and magnesium that dissolve from the sand and clay below. As water sits in contact with these rock layers, the minerals dissolve slowly into the water. Moderate hardness is common across wells throughout the county.
Good news--wells in Dooly County do not show contamination exceeding EPA health standards. Your well water is free from serious health threats based on what is common in the county.
Wells in this county do have moderate hardness and iron at levels that affect everyday life. You may notice orange or reddish staining on fixtures, in toilets, or on laundry. Hard water leaves scale buildup inside pipes and on appliances, and it can shorten the lifespan of water heaters and dishwashers over time.
We recommend testing your well to find out what is actually in your water, since every well is different and yours could have higher or lower levels than the county average. Testing is the only way to know what treatment your specific well needs. A basic water test runs $50 to $100, while a comprehensive metals and minerals panel costs $200 to $400. Water softeners or iron filters can address these mineral concerns once you know your exact levels.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
