Well Water in Jack County: What to Test and Why

Iron, fluoride, and arsenic are present in Jack County's groundwater. Fluoride and iron exceed EPA health standards, which means these contaminants are at levels that require attention.

These contaminants come from the rock itself. The other rock types beneath Jack County naturally release iron and fluoride into the water as it passes through underground. Arsenic also occurs naturally in some of these rock layers and enters wells the same way.

Groundwater in this county is notably high in iron. Iron dissolves out of the rock as water moves slowly through the ground over time. This elevated iron character shows up across many wells in the county.

Wells in Jack County commonly show fluoride and iron at levels above EPA health standards. Fluoride in excess can affect bone and dental development, especially in children. Iron itself is not a health concern at the levels found here, but arsenic also appears in some county wells and can damage kidneys and other organs over time.

Iron in county well water creates reddish or brown stains on fixtures, laundry, and surfaces that are hard to remove. You may notice a metallic or bitter taste in your water. These stains build up over time and can be stubborn.

Your well may have much higher or lower levels than what is common across the county. 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 between $200 and $400. Iron filters and reverse osmosis systems can help address these concerns.
