EPA records for CLARKSDALE PUBLIC UTILITIES • Updated October 2026
Grade F — based on EPA compliance records, lead testing and PFAS monitoring
CLARKSDALE PUBLIC UTILITIES 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.
Clarksdale, MS tap water is legal to drink but grades F on EPA's records, mainly because of 6 health-based EPA violations in the last five years. A certified filter matched to that finding is a reasonable precaution.
Clarksdale, MS tap water is legal to drink but grades F on EPA's records, mainly because of 6 health-based EPA violations in the last five years. A certified filter matched to that finding is a reasonable precaution.
CLARKSDALE PUBLIC UTILITIES's most recent Lead and Copper Rule result (2022-01-01 to 2024-12-31) was 2.2 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.
No. None of the 381 UCMR5 PFAS results for CLARKSDALE PUBLIC UTILITIES (2023-10-18 to 2024-04-25) were at or above the reporting limit of roughly 3–5 ppt.
CLARKSDALE PUBLIC UTILITIES has 12 violations on file since 2016: 6 health-based in the last five years and 3 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
CLARKSDALE PUBLIC UTILITIES reports groundwater as its primary source and serves about 14,903 people (EPA PWSID MS0140002).
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 CLARKSDALE PUBLIC UTILITIES
Well below the 15 ppb action level. In the most recent monitoring period on file (2022-01-01 to 2024-12-31), 90% of the homes CLARKSDALE PUBLIC UTILITIES sampled had lead at or below 2.2 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.
| Monitoring period | Lead 90th percentile | vs 15 ppb action level |
|---|---|---|
| 2022-01-01 → 2024-12-31 | 2.2 ppb | Well below the 15 ppb action level |
| 2019-01-01 → 2021-12-31 | 3.9 ppb | Well below the 15 ppb action level |
| 2016-01-01 → 2018-12-31 | 8.9 ppb | Below the action level, but detectable |
| 2014-01-01 → 2016-12-31 | 4.9 ppb | Well below the 15 ppb action level |
| 2011-01-01 → 2013-12-31 | 8.7 ppb | Below the action level, but detectable |
| 2008-01-01 → 2010-12-31 | 5.7 ppb | Below the action level, but detectable |

EPA UCMR5 monitoring, 2023-10-18 to 2024-04-25 · 381 PFAS results at entry points to the distribution system
No PFAS detected. None of the 381 UCMR5 PFAS results for CLARKSDALE PUBLIC UTILITIES were at or above the method reporting limit. Reporting limits are about 3–5 ppt, so “not detected” means below that threshold — not proven zero.
| Compound | Detects / samples | Max (ppt) | Reporting limit | EPA MCL |
|---|---|---|---|---|
| PFOA | 0 / 13 | < 4 | 4 ppt | 4 ppt |
| PFOS | 0 / 13 | < 4 | 4 ppt | 4 ppt |
| PFHxS | 0 / 13 | < 3 | 3 ppt | 10 ppt |
| PFNA | 0 / 13 | < 4 | 4 ppt | 10 ppt |
| HFPO-DA | 0 / 13 | < 5 | 5 ppt | 10 ppt |
| PFBS | 0 / 13 | < 3 | 3 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.
Lithium (also monitored under UCMR5, not a PFAS): detected in 14 of 14 samples, max 32.6 µg/L. There is no federal limit for lithium.

A point-of-use (under-sink) system typically runs $200-$600 installed; whole-house treatment $1,000-$3,000+ depending on flow and what has to come out. Tell us where you are and a certified water-treatment installer serving Clarksdale will follow up - no obligation.
Groundwater systems draw from wells; naturally occurring arsenic, nitrate, radium and uranium are the readings to watch, along with PFAS near industrial or military sites.
How to test your tap water and the treatment options that actually fit Clarksdale 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 Clarksdale 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 Clarksdale 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.
