Well owners in Meeker County need to know that their groundwater contains manganese, iron, arsenic, lead, nitrate, PFOA, PFOS, and sulfate. Multiple contaminants exceed EPA health standards, making testing and treatment important for your household.
These contaminants come from two sources working together. Iron and manganese dissolve naturally from the rock as groundwater moves through it. Arsenic, lead, nitrate, PFOA, and PFOS enter from human activities--septic systems, fertilizer use, and industrial or firefighting sources--that allow these substances to seep down into the water below.
Groundwater in Meeker County is very hard, driven by elevated calcium and magnesium from the bedrock, and also contains very high iron. The local rock composition naturally releases these minerals as water flows through it over time. Very hard water with high iron content is widespread across wells throughout the county, though individual wells vary in what they contain.
Meeker County wells commonly contain arsenic, lead, nitrate, PFOA, PFOS, iron, and manganese at levels that exceed EPA health standards. Arsenic and lead are cancer risks and can damage organs and development. Nitrate interferes with oxygen in the blood. PFOA and PFOS are industrial chemicals linked to serious health effects. Manganese at high levels can affect the nervous system.
The water in this county is extremely hard, which means scale builds up inside pipes and appliances like water heaters and dishwashers, shortening their lifespan. Iron creates rust-colored stains on fixtures and laundry. You may notice a metallic or unpleasant taste. Scale accumulation makes soap less effective and clogs plumbing over time.
We recommend getting your well tested with a comprehensive panel since multiple contaminants exceed health standards in the county. Your well could have higher or lower levels than what is common here--testing is the only way to know what is actually in your water and how to treat it properly. A comprehensive metals and minerals panel runs $200 to $400. Water softeners address hardness, while specialized filters or reverse osmosis can target specific 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.
