7 unresolved violations on record
EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.
See what was cited ↓Lead is well under the limit
90th-percentile lead is 0.6 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.
See the trend ↓HAA5 is approaching its limit
Measured at 56.9 µg/L — 95% of the 60 µg/L limit. Within the rules, but with less headroom than you'd want.
See the ledger ↓Lake Clarke Shores's drinking water received a grade of B (77.4 out of 100), indicating good water quality. The city's 3 water systems serve approximately 4,113 residents using purchased ground water.
Lead levels were measured at 0.6 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 37 violations on record, including 7 health-based violations. 7 remain unresolved.
Lake Clarke Shores ranks #165 out of 366 cities in Florida for water quality, placing it mid-range in the state. Lake Clarke Shores purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition. Haloacetic acid (HAA5) levels were elevated at 56.9 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts. The system has seen 13 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Lake Clarke Shores's water
Every contaminant flagged in Lake Clarke Shores, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Near MCL — EPA MCL: 60 µg/L
Disinfection byproducts form when chlorine reacts with organic matter in source water, typically peaking in warm months. An activated-carbon filter reduces them at the tap.Full contaminants report

03Lake Clarke Shores's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 37 violations on record, including 7 health-based violations. 7 remain unresolved.
6 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▼ Down 1.6 ppb since 1993. Latest reading: 1.4 ppb (2024) — 9% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Lake Clarke Shores's water comes from
Lake Clarke Shores purchases its water supply from a regional wholesale provider rather than treating raw water directly.
Purchased Groundwater
Water is bought from a regional wholesaler; quality starts at the supplier's intake and treatment.
Wholesale supplier
Primary treatment happens at the wholesaler; the local utility maintains disinfectant residual in its pipes.
3 systems
3 water systems, operated under private ownership.
4,113 people
Residents served across Lake Clarke Shores's service area.
Water quality depends on both the wholesaler's treatment standards and the condition of Lake Clarke Shores's local distribution pipes and storage facilities. Purchased water systems are common in suburban areas and smaller communities that lack the infrastructure for independent treatment. The system is operated by private ownership and serves approximately 4,113 people through 3 water systems.

05Pressure on Lake Clarke Shores's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
5 facilities within 10 miles reported 5 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Drought
Palm Beach County is in D3 (extreme drought) per the U.S. Drought Monitor (week of Jul 2026). Drought can raise disinfection-byproduct levels and taste/odor issues as utilities draw from lower reservoirs.
