Well Water in Garza County: What to Test and Why

Groundwater in Garza County contains arsenic, fluoride, iron, and manganese at levels that exceed EPA health standards. These contaminants are present at concerning concentrations that warrant attention from well owners.

These metals occur naturally in the rock and soil layers beneath the county. As water moves slowly through the ground, it dissolves these elements from the local rock and carries them into the aquifer. This process is common in areas where the underlying geology contains these minerals.

Groundwater in this county is notably high in iron, which is the dominant mineral affecting water character. Iron concentrates in this water because it leaches from the rock layers as groundwater moves through the aquifer over time. Iron concentrations at these levels are widespread across wells in the county.

Arsenic and fluoride in wells across Garza County exceed EPA health standards. Arsenic can damage kidneys and increase cancer risk over many years. Fluoride at elevated levels can weaken tooth enamel and affect bone health. Iron and manganese also exceed standards in county wells. Manganese at concerning levels can harm the nervous system, especially in children.

Iron in the groundwater here leaves reddish-brown stains on plumbing fixtures, laundry, and dishes. These stains are stubborn and hard to remove. The iron can also clog pipes and reduce water flow over time. You may notice a metallic taste in the water when iron levels are high.

Testing your well is the only way to know what is actually in your water. Every well in Garza County is different--yours could have higher or lower levels than what is common here. We recommend a comprehensive metals and minerals panel to check for all these contaminants, which typically costs $200 to $400. Iron filters or water softeners can help treat elevated iron and improve water quality.
