West Virginia ranks 48th out of 50 states for drinking water quality, receiving an average score of 53 and a grade of D. Serving a population of 1,498,029 across 248 water systems, the state has logged 11,085 violations. This indicates significant challenges in maintaining drinking water safety standards across the region.
Key Findings for West Virginia
Reviewing EPA SDWIS data for 2026, here's what defines West Virginia's water quality landscape:
- The Appalachian region's history of legacy coal mining and industrial activity can contribute to metal and chemical runoff entering groundwater and surface water sources.
- Rural mountainous terrain poses infrastructure and funding challenges for the state's 248 water systems, potentially leading to monitoring and reporting violations.
- Older drinking water systems in rural communities often struggle with aging distribution networks, which increases the risks of system-wide pipe corrosion and associated contaminants.
Most Common Contaminants in West Virginia
Here's what West Virginia residents should know about the contaminants most relevant to their water:
Lead
Aging water infrastructure and household plumbing in older residential areas can leach lead into tap water, presenting a risk of exposure.
Disinfection Byproducts
These chemical compounds can form during the water treatment process when disinfectants like chlorine react with naturally occurring organic matter in raw water sources.
Total Coliform
Often found in rural or mountainous areas relying on surface water or shallow wells, the presence of these bacteria can indicate potential pathways for contamination.
