EPA records for PARK RIDGE • Updated October 2026
Grade A — based on EPA compliance records, lead testing and PFAS monitoring
PARK RIDGE has a clean recent record: no health-based violations in the last five years and no lead, PFAS or historical monitoring result that costs it more than a few points.
Yes — by EPA's records Park Ridge, IL tap water is safe to drink and earns an A. The grade rests on lead at 6.8 ppb (90th percentile) — under the 15 ppb action level but above 5 ppb. The catch is lead pipes: Park Ridge's water system reports 3,121 lead or galvanized service lines still in the ground in EPA's 2026 inventory, and lead leaches from those pipes after the water leaves the plant. If your home is on one, test at the tap or use a filter certified to NSF/ANSI 53 for lead.

PARK RIDGE's most recent Lead and Copper Rule result (2026-01-01 to 2026-06-30) was 6.79 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 116 UCMR5 PFAS results for PARK RIDGE (2023-02-13 to 2023-11-13) were at or above the reporting limit of roughly 3–5 ppt.
PARK RIDGE has 6 violations on file since 2016: 0 health-based in the last five years and 2 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
PARK RIDGE reports purchased surface water as its primary source and serves about 39,800 people (EPA PWSID IL0312460).
Optional but sensible. The findings on this page are below federal limits; an NSF-certified pitcher or under-sink filter handles lead and improves taste.

Lead was found at 6.8 ppb (90th percentile) in Park Ridge's latest tap sampling — below the action level, but there is no safe level of lead.

EPA Lead and Copper Rule 90th-percentile results reported by PARK RIDGE
Below the action level, but detectable. In the most recent monitoring period on file (2026-01-01 to 2026-06-30), 90% of the homes PARK RIDGE sampled had lead at or below 6.79 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 |
|---|---|---|
| 2026-01-01 → 2026-06-30 | 6.79 ppb | Below the action level, but detectable |
| 2025-07-01 → 2025-12-31 | 10.6 ppb | Below the action level, but detectable |

EPA UCMR5 monitoring, 2023-02-13 to 2023-11-13 · 116 PFAS results at entry points to the distribution system
No PFAS detected. None of the 116 UCMR5 PFAS results for PARK RIDGE 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 / 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 |
“< 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 PARK RIDGE · finished water only · dated data, released 2024
These are the regulated-contaminant samples PARK RIDGE reported to its state between 2012 and 2019 — the most recent nationwide sample-level dataset EPA has published. Every scored contaminant stayed within its Maximum Contaminant Level (MCL) and averaged below 80% of the limit. Treat this as history, not today's tap water.
| Contaminant | Samples | Average | Max | EPA limit | Status |
|---|---|---|---|---|---|
| Total trihalomethanes (TTHM) | 71 | 30.472 µg/L | 56.8 µg/L | 80 µg/LMCL (LRAA) | Within MCL |
| Haloacetic acids (HAA5) | 71 | 14.668 µg/L | 26.7 µg/L | 60 µg/LMCL (LRAA) | Within MCL |
| Lead (tap samples) | 6013 detects | 1.01 µg/L | 19 µg/L | 15 µg/Laction level (90th percentile) | Reported, not scored (compliance is on the 90th percentile) |
| Copper (tap samples) | 604 detects | 13.833 µg/L | 307 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.

PARK RIDGE · 12,648 service lines inventoried · Q2 2026 snapshot
PARK RIDGE reports 3,121 service lines that are lead or galvanized-requiring-replacement (25% of the lines it has inventoried), plus 5,530 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 Park Ridge 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 Park Ridge 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 Park Ridge 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.
