Manganese, iron, chloride, and lead are present in Limestone County groundwater. Several of these contaminants exceed EPA health standards, making testing important for well owners in this area.
The rock beneath this county naturally releases iron and manganese into the water as it passes through. Chloride and lead can also enter from a mix of natural sources and human activity, including older plumbing and salt deposits in deeper layers.
Groundwater in this county is moderately hard, with moderate iron levels that come from the surrounding rock. The water also carries elevated sodium from the local geology. These mineral and salt characteristics show up across many wells throughout the county.
Wells in Limestone County commonly contain chloride, iron, lead, manganese, and sulfate at levels that exceed EPA health standards. Lead damages children's brain development and learning. Manganese harms the nervous system. Iron, chloride, and sulfate can damage organs over time with repeated exposure. These metals and minerals come from the rock and soil layers beneath the county.
County wells have moderately hard water that leaves scale buildup on fixtures and inside pipes. Iron causes orange or brown stains on clothes, sinks, and laundry. The high sodium content affects the taste of the water. Hard water can shorten the lifespan of water heaters and dishwashers.
Your well is unique and may have higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel, which typically costs $200 to $400. Iron filters and softeners can help remove these contaminants.

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.
