Lead pipe replacement law in Arkansas
Arkansas has not set its own state-specific lead service line replacement deadline beyond the federal requirement below. The rule is implemented through the Arkansas Department of Health (ADH), which required every public water system to submit a baseline inventory by October 16, 2024 under the federal Lead and Copper Rule Improvements, rather than setting an earlier state-specific replacement date.
Separately from any state law, the EPA's federal Lead and Copper Rule Improvements require every water system nationwide to submit a baseline inventory and an approved replacement plan by November 1, 2027, then fully replace all lead and "galvanized requiring replacement" lines under its control on a schedule of 10 years or less from that date, replacing at least 10% of its known lead/GRR lines per year. A narrow exception allows a longer schedule only for the roughly 1% of systems with an unusually dense concentration of lead lines, and partial (non-emergency) replacements are prohibited.
Known gaps in Arkansas coverage
Fayetteville, Arkansas's second-largest system by our research, is not covered here -- it has a real, dedicated per-address inventory dataset with a "Suspected Lead?" field, but its public query endpoint currently returns a server error on every request tried (a technical outage, not a permissions block, the same pattern found in Montana's Billings). A "not found" result for a Fayetteville-area address means unpublished here, not confirmed lead-free.
