EPA records for CITY OF SHREVEPORT WATER SYSTEM • Updated September 2026
Grade F — based on EPA compliance records, lead testing and PFAS monitoring
CITY OF SHREVEPORT WATER SYSTEM has serious issues in EPA's records: repeated health-based violations, unresolved violations, PFAS above the federal limit or lead near the action level. We recommend filtering drinking water.
Shreveport, LA tap water is legal to drink but grades F on EPA's records, mainly because of 20 health-based EPA violations in the last five years and low-level PFAS (PFBA) detected below federal limits. A certified filter matched to those findings is a reasonable precaution.
Shreveport, LA tap water is legal to drink but grades F on EPA's records, mainly because of 20 health-based EPA violations in the last five years and low-level PFAS (PFBA) detected below federal limits. A certified filter matched to those findings is a reasonable precaution.
CITY OF SHREVEPORT WATER SYSTEM's most recent Lead and Copper Rule result (2025-01-01 to 2025-12-31) was 0.92 ppb at the 90th percentile, below EPA's 15 ppb action level. Because lead usually comes from service lines and household plumbing, homes built before 1986 should still test at the tap.
Yes. EPA's UCMR5 sampling (2023-06-13 to 2025-03-31) detected PFBA, all below federal MCLs. Reverse osmosis and certified activated-carbon filters reduce PFAS.
CITY OF SHREVEPORT WATER SYSTEM has 24 violations on file since 2016: 20 health-based in the last five years and 1 monitoring or reporting violation in that window. Monitoring violations are paperwork lapses, not measured contamination.
CITY OF SHREVEPORT WATER SYSTEM reports surface water as its primary source and serves about 192,378 people (EPA PWSID LA1017031).
We recommend one. Check which contaminant the violations involved (table above) and choose a filter certified for it.

EPA Lead and Copper Rule 90th-percentile results reported by CITY OF SHREVEPORT WATER SYSTEM
Well below the 15 ppb action level. In the most recent monitoring period on file (2025-01-01 to 2025-12-31), 90% of the homes CITY OF SHREVEPORT WATER SYSTEM sampled had lead at or below 0.92 ppb.
EPA's action level is 15 ppb (dropping to 10 ppb under the 2024 Lead and Copper Rule Improvements). There is no safe level of lead; the 90th-percentile figure describes the system, not your tap — homes with lead service lines or pre-1986 plumbing can be higher.

EPA UCMR5 monitoring, 2023-06-13 to 2025-03-31 · 116 PFAS results at entry points to the distribution system
PFBA detected at low levels; no compound was at or above its federal MCL. Detections below the MCL are common in surface-water systems and are reported here exactly as EPA published them.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 4 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 4 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 4 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 4 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 4 | < 3 | 3 ppt | hazard index only |
| PFBA | 3 / 4 | 7.5 | 5 ppt | hazard index only |
“< 4 ppt” means below the laboratory reporting limit, not zero. ppt = parts per trillion (ng/L). Results are for finished water leaving the treatment plant.

EPA Six-Year Review 4 compliance samples for CITY OF SHREVEPORT WATER SYSTEM · finished water only · dated data, released 2024
These are the regulated-contaminant samples CITY OF SHREVEPORT WATER SYSTEM reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Total trihalomethanes (TTHM), Haloacetic acids (HAA5) are flagged below; the status column explains why. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Arsenic | 96 detects | 0.73 µg/L | 2 µg/L | 10 µg/LMCL | Within MCL |
| Fluoride | 9 | 0.843 mg/L | 0.95 mg/L | 4 mg/LMCL | Within MCL |
| Chromium (total) | 90 detects | 0 µg/L | ND | 100 µg/LMCL | Not detected |
| Uranium (combined) | 60 detects | 0 µg/L | ND | 30 µg/LMCL | Not detected |
| Radium-226/228 | 50 detects | 0 pCi/L | ND | 5 pCi/LMCL | Not detected |
| Gross alpha | 60 detects | 0 pCi/L | ND | 15 pCi/LMCL | Not detected |
| Total trihalomethanes (TTHM) | 268 | 40.97 µg/L | 218 µg/L | 80 µg/LMCL (LRAA) | 20 single samples over MCL; average within limit |
| Haloacetic acids (HAA5) | 262 | 29.198 µg/L | 188 µg/L | 60 µg/LMCL (LRAA) | 18 single samples over MCL; average within limit |
| Lead (tap samples) | 15745 detects | 0.535 µg/L | 11 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 15712 detects | 14.681 µg/L | 1200 µg/L | 1300 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
Averages count non-detects as zero. TTHM and HAA5 limits are locational running annual averages, so a single high sample is not a violation — we grade those on the average only. Lead and copper rows are individual tap samples and are shown for context; compliance (and our score) uses the 90th-percentile result above. LRAA = locational running annual average; ND = not detected.

CITY OF SHREVEPORT WATER SYSTEM · 92,293 service lines inventoried · Q2 2026 snapshot
CITY OF SHREVEPORT WATER SYSTEM reports 1,799 service lines that are lead or galvanized-requiring-replacement (1.9% of the lines it has inventoried), plus 85,680 lines whose material is still unknown. A lead service line is the pipe between the water main and a building, so treated water can pick up lead after it leaves the plant — which city-level testing does not capture. Under EPA's Lead and Copper Rule Improvements, utilities must replace lead lines within 10 years starting in 2027.

Surface-water systems draw from rivers, lakes or reservoirs and must filter and disinfect, which is why disinfection byproducts (TTHM, HAA5) are the readings to watch.
How to test your tap water and the treatment options that actually fit Shreveport homes
The most reliable way to know what is actually coming out of your tap is a certified mail-in lab test. City-wide EPA data (like the report above) reflects the water leaving the treatment plant, but contaminants such as lead and copper can be picked up from your own service line and household plumbing — so the water at your Shreveport faucet can differ from the system average. A state-certified lab measures dozens of contaminants at once with results you can trust; you can also find one near you through the EPA's certified-lab list at epa.gov/dwlabcert. Hardware-store test strips are cheaper and instant, but they only screen for a few basics (chlorine, hardness, pH, and a rough lead pass/fail) and are far less accurate — treat them as a first look, not a diagnosis.
Match the treatment to what your test finds. Reverse osmosis (RO) removes the widest range of contaminants — lead, arsenic, nitrate, PFAS, and dissolved solids — which makes an under-sink reverse osmosis system the most thorough choice for Shreveport households with heavy-metal or PFAS concerns. If your main issue is taste, odor, or chlorine, an activated carbon filter (pitcher, faucet, or under-sink) is simpler and cheaper and handles chlorine and many organic compounds well, though carbon alone does not remove arsenic, nitrate, or most PFAS. NSF-certified pitchers rated for lead reduction are the easiest way to start today while you decide on a permanent setup.
