London Water Quality Summary

London, KY receives a water quality score of 50/100 (Grade D) based on EPA Safe Drinking Water Information System (SDWIS) compliance data for 5 public water systems serving the area.

London's water quality score is below the national average, indicating a history of EPA violations or elevated contaminant levels. Residents are encouraged to check their specific water system report and consider additional filtration.

London's score of 50 is 16 points below the Kentucky state average of 66, and below the nationwide average of roughly 78/100 across all U.S. states.

As a mid-size city situated in Kentucky's Appalachian and bluegrass region, London relies on multiple water systems that collectively exhibit concerningly low performance marks. For local residents and prospective homebuyers, this subpar evaluation suggests that tap water quality is not consistently meeting optimal standards, a challenge sometimes compounded by the environmental legacy of coal mining in the state's eastern counties. Navigating these public utility shortcomings means households may want to remain vigilant about their domestic water supply and monitor local utility updates closely.

Water quality data is sourced from the U.S. EPA SDWIS database and updated quarterly. Learn about our scoring methodology → Read our Kentucky water quality rankings report →
