Spring Valley Water Authority water quality

Tuscumbia, AL · serves 5,520 people (1,840 connections) · Purchased surface water · Local government · EPA ID AL0000329

Data: U.S. EPA · How we read the data · How we check it

Buys water from Lagrange Mountain Water Authority, West Lawrence Water Coop, Muscle Shoals Utility Board, Tuscumbia Water Works. Treated water bought from another system can carry that system's contaminants.

Summary

PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.

Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.

PFAS
Above limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 8.57 ppt vs a limit of 4 ppt, PFOS 14 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lead
Below action level0 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period Jan 2024 – now, still in progress (results reported so far). Your home's pipes can make yours higher.
Violations
Resolved1 health-based violation since 2016, most recently Jun 2026. One required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Jun 2026. What to do if you get a notice.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 3 entry points tested Jan 2024 to Oct 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.

For context: the PFOA average is higher than at 92% of the Alabama systems EPA tested and the PFOS average is higher than at 93% of the Alabama systems EPA tested.

29 PFAS tested, 6 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions

Is Spring Valley Water Authority water safe to drink?

Spring Valley Water Authority had 1 health-based violation since 2016, all since resolved. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.

Does Spring Valley Water Authority water have PFAS?

Yes. EPA's 2023–2025 testing of Spring Valley Water Authority found 6 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 8.57 ppt, PFOS 14 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in Spring Valley Water Authority water?

The most recent 90th-percentile lead result for Spring Valley Water Authority is 0 ppb, for the monitoring period that began Jan 2024 (still in progress). The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
