Water Quality Summary
Tap water quality in Arkadelphia, Arkansas (71923) receives an overall grade of A (Lower record-based concern) with a score of 93 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is roughly in line with the Arkansas state average of 97. Compared to the national average (75), this area performs significantly better. The area is served by 6 water systems providing water to approximately 12,718 people, using surface water sources. PFAS testing detected 1 compound, all below the EPA final MCL values used for comparison.
A score of 93/100 means public water-system records for Arkadelphia, AR show relatively few concerns in the US Water Score model. This is an internal score, not an EPA safety rating, and it does not guarantee conditions at any specific tap.
Health Information
Lead is a toxic metal that can leach from aging pipes and plumbing fixtures.
Even low levels of lead exposure can cause developmental delays in children, kidney damage, and cardiovascular effects in adults. The EPA action level is 15 ppb, but health experts recommend no safe level of lead in drinking water.
Lead enters water primarily through corrosion of lead service lines, lead solder, and brass fixtures — especially in homes built before 1986.
If lead is detected above 1 ppb, consider using a certified lead-removal filter (NSF/ANSI 53) for drinking and cooking water. Run cold water for 30 seconds before use if water has been sitting in pipes.
Common Questions
Based on public water-system records, Arkadelphia, Arkansas receives an internal US Water Score grade of A (Lower record-based concern) with a score of 93/100. This indicates relatively few system-level concerns in our model, but it is not an EPA safety rating and does not guarantee tap conditions inside individual homes.
ZIP code 71923 is served by 6 water systems using surface water sources, providing water to approximately 12,718 people. Surface water systems are more susceptible to contamination from agricultural runoff, industrial discharge, and weather events, but typically undergo more extensive treatment including filtration and disinfection.
Lead levels in the public-system record for Arkadelphia, Arkansas are 18.0 ppb, above the currently applicable EPA action level of 15 ppb. EPA's Lead and Copper Rule Improvements lower that action level to 10 ppb when the new requirements take effect. This system-level result does not measure an individual tap; consider a certified lead-removal filter and independent tap testing.
1 PFAS compound were detected in water serving Arkadelphia, Arkansas, with reported values below the EPA final MCL values used by this site. This comparison is informational: federal compliance timelines and the status of some PFAS standards are still evolving.
