Well Water in Smith County: What to Test and Why

Iron, manganese, and lead are present in Smith County groundwater and well owners should be aware of them. These contaminants exceed EPA health standards at concerning levels in this area.

The rock layers beneath Smith County naturally contain iron and manganese, which dissolve into groundwater as water moves through the soil and rock. Lead enters groundwater through corroded pipes and old well components rather than from the rock itself. The coastal uplands geology here is prone to releasing these metals into the water supply.

Groundwater in this county is soft, with moderate iron being the main mineral character. Iron concentration comes from the natural composition of the coastal uplands rock formation, which weathers and releases iron into the water as it percolates down. Most wells across Smith County show these same characteristics, though the amount varies from well to well.

Iron, lead, and manganese are found at levels above EPA health standards in wells throughout Smith County. Lead can harm children's brains and nervous systems, affecting learning and behavior. Iron buildup in the body over time can cause problems. Manganese exposure can affect how the nervous system works.

County well water is relatively soft, which is good for your pipes and appliances. However, iron in these wells does cause orange or brown staining on clothes, dishes, and fixtures. You might notice a metallic or unpleasant taste in the water.

Since every well is different, your water could have much higher or lower levels than what is common in the county, and the only way to know what is actually in your well is to test it. We recommend getting a comprehensive metals and minerals panel, which usually costs between two hundred and four hundred dollars. Iron filters or lead treatment systems can help reduce these contaminants once you know your levels.
