Well Water in West Virginia
Contaminant risks, testing requirements, and treatment recommendations for private well owners in West Virginia.
West Virginia Geology and Groundwater
West Virginia sits on Appalachian sandstone and shale. This geology directly determines what contaminants are likely in private well water. Based on this geology, West Virginia well owners face elevated risk for iron and manganese from dissolved minerals. Moderate risk exists for radon.
Contaminant Risk Profile
| Contaminant | Risk Level | Why |
|---|---|---|
| Arsenic | Low risk | Generally low in this region's geology. |
| Nitrate | Low risk | Generally low outside of agricultural areas. |
| Radon | Moderate risk | Some bedrock types in this state produce radon. |
| PFAS | Low risk | Fewer known contamination sources, but PFAS can travel far through groundwater. |
| Iron/Manganese | Elevated risk | Very common in this state's groundwater. Causes staining but is not a health risk. |
How West Virginia Compares: Municipal Water Data
CheckMyTap tracks water quality for 6 cities in West Virginia. While these numbers reflect municipal water (not private wells), they indicate the baseline mineral content of West Virginia's water sources. Private wells often draw from the same aquifers but with less treatment.
| Metric | West Virginia Average | National Average |
|---|---|---|
| Hardness | 116 PPM (moderately hard) | 170 PPM |
| Hardness range | 70 - 150 PPM | 25 - 400+ PPM |
| Lead (avg municipal) | 0.9 ppb | 3.2 ppb |
| Nitrate (avg municipal) | 0.5 mg/L | 1.1 mg/L |
| Cities with PFAS detected | 2 of 6 | ~45% nationally |
| Cities exceeding PFAS MCL (4 ppt) | 2 |
Hardest water in West Virginia: Huntington (150 PPM), Wheeling (135 PPM), Parkersburg (120 PPM), Charleston (113 PPM), Morgantown (105 PPM).
Testing Requirements in West Virginia
West Virginia does not have a statewide mandatory testing requirement for existing private wells. Regardless of state requirements, the EPA recommends testing annually for:
- Every year: Total coliform bacteria, E. coli, nitrate, pH, and total dissolved solids
- At least once: Arsenic, lead, copper, fluoride, and any contaminant identified as a local risk
- Recommended for West Virginia: Radon in water (granitic bedrock states have higher risk)
- After events: Retest after flooding, well repairs, nearby construction, or any change in taste/color/odor
Recommended Treatment for West Virginia Wells
Based on West Virginia's geology and common contaminant risks, these treatment systems address the most likely issues:
Whole-house oxidation filter removes iron staining and manganese discoloration

Frequently Asked Questions
Is well water in West Virginia safe to drink?
Well water quality in West Virginia varies significantly by location and geology. West Virginia sits on Appalachian sandstone and shale. Key concerns include iron and manganese from dissolved minerals. The only way to know your specific water quality is to test it. Use our free interpreter to understand your results.
How often should I test my well water in West Virginia?
The EPA recommends testing annually for bacteria (total coliform, E. coli), nitrate, total dissolved solids, and pH. Radon testing is also recommended in West Virginia. Test more frequently if you notice changes in taste, color, or odor, or after flooding, nearby construction, or well repairs.
Does West Virginia require well water testing?
West Virginia does not have a statewide mandatory testing requirement for existing private wells. However, the EPA strongly recommends annual testing regardless of state requirements. Your county health department may have additional local requirements.
What is the average water hardness in West Virginia?
Municipal water in West Virginia averages 116 PPM across 6 cities tracked by CheckMyTap, ranging from 70 to 150 PPM. Private well water typically runs 20-50% harder than city water because groundwater has more contact time with mineral formations. Many West Virginia well owners have manageable hardness levels, though local variation is significant. Check your city's data.
