Kanawha Valley Water System Context

Charleston’s water comes mainly from surface water sources managed by the WVAWC-Kanawha Valley District. This public water system serves over 200,000 people through more than 90,000 connections. The water is treated and distributed to homes, but lead presence is influenced by factors beyond the source, including household plumbing.

Why Aesthetic Secondary Standards Differ From Health-Based Limits for Lead

Lead is regulated for health risk, not for taste or appearance

Lead is a toxic metal that can cause serious health issues if ingested at elevated levels over time. Regulatory agencies set health-based action levels to protect consumers. Aesthetic standards, by contrast, address issues like taste or discoloration but do not apply to lead because its presence always raises health concerns rather than aesthetic ones.

Additional Questions for Commercial or Industrial Water Users

Households focus on direct consumption risk

Commercial or industrial users may need to address lead in water for processes, equipment corrosion, or regulatory compliance beyond drinking water standards. Residential households primarily consider lead levels in tap water for drinking and cooking safety.

Seasonal and Multi-Year Variation in Charleston’s Lead Records

Sampling shows zero lead at the 90th percentile in 2025

According to EPA public water system data for the Kanawha Valley District, lead was measured at 0 mg/L for the 90th percentile of samples taken in 2025. This indicates that most homes sampled had no detectable lead concentration at that time. Note that these results reflect distribution system sampling, not source water.

How the Pentair Lead in Water Filter Treats This Constituent

Effective reduction of lead particles at the tap

The Pentair Lead in Water Filter uses proven filtration technology to capture and reduce lead from water before consumption. It ships ready to configure for residential point-of-use treatment, offering an extra layer of protection against lead that may leach from plumbing materials.

What to Record Before Seeking Treatment Guidance

Document your home’s water testing and plumbing details

• Have a current test result for lead from water taken at your tap to understand your specific water quality.
• Note the age and materials used in your household plumbing, as lead can enter water through older pipes or solder.
• Record any water use patterns or symptoms such as discoloration or metallic taste, though these are not definitive indicators of lead.

Understanding 'Detected', 'Median', and 'Range' in Sampling Data

What the terms mean regarding Charleston’s public water system

• Detected: Instruments measured lead presence, not a violation or confirmed health risk.
• Median: The middle value in sample results, showing typical levels among tested homes.
• Range: The spread between lowest and highest detected values, indicating variation over time or location.

Conclusions You Should Not Draw From Area Data

The government record for Charleston’s Kanawha Valley District shows no health-based violations for lead. This does not guarantee your household water is free from lead—it only represents system-wide samples. Individual homes may differ due to plumbing or other factors, so personal testing is essential to determine your own water’s lead content. The Pentair Lead in Water Filter provides a documented method to reduce lead where concerns exist.
