Wells in Richmond have iron and manganese at levels above EPA health standards, along with arsenic present in the groundwater. These contaminant levels are high enough that well owners should have their water tested and consider treatment.
The rock beneath Richmond contains naturally occurring iron and manganese minerals that dissolve into groundwater as water moves through the Early Mesozoic basin rock layers. Arsenic also comes from these rocks. This is a natural part of the geology here, not from pollution on the land surface.
Groundwater in Richmond is soft and low in salt and sulfur, but iron is the main mineral that shows up in wells at moderate levels. Iron comes from the rocks that make up the aquifer in this area. Many wells in Richmond will have detectable iron in their water.
Wells in Richmond show elevated iron and manganese at levels above EPA health standards. Iron can cause problems with your blood and organs over time, especially in children and pregnant women. Manganese affects your brain and nervous system, and long-term exposure is a concern for your family's health. Testing your specific well is the only way to know if these metals are present in your water.
Iron in county wells creates orange or brown staining on sinks, tubs, and laundry. You might notice a metallic taste in your water or see rust-colored particles. The good news is that Richmond's wells are generally soft, so you won't deal with heavy scale buildup on your pipes and fixtures the way people in harder-water areas do.
We recommend getting your well tested right away since multiple metals exceed health standards in this area. A comprehensive metals and minerals panel typically costs $200 to $400 and will tell you exactly what's in your water. Testing is the only way to know if your well needs treatment like an iron filter or water softener. Once you know what you're dealing with, you can choose the right fix for your family.

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.
Data shows potential risk — a certified test confirms whether your water is affected.
