See the record ↓Halstead's drinking water received a grade of C+ (68.7 out of 100), indicating fair water quality. The city's 2 water systems serve approximately 2,505 residents using purchased ground water.
Lead levels were measured at 0.0 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 42 violations on record, including 5 health-based violations. 18 remain unresolved.
Halstead ranks #247 out of 312 cities in Kansas for water quality, placing it among the lowest-rated in the state. Halstead purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition. As a small community water system, Halstead may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 9 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Halstead's water
Every contaminant flagged in Halstead, 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.
Over Limit — EPA Action Level: 1.3 mg/L
Exceeds the EPA action level. Copper leaches from household plumbing — flush taps for 30 seconds before drinking, and consider a certified filter.Full contaminants report
| Contaminant | Detected Level | EPA Limit | Unit | Category | Status |
|---|---|---|---|---|---|
| Lead (90th percentile) LeadHeavy Metal A toxic heavy metal that can leach into drinking water from older pipes, solder, and fixtures. No amount of lead in water is considered safe.

04Where Halstead's water comes from
Halstead 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.
2 systems
2 water systems, operated under local government ownership.
2,505 people
Residents served across Halstead's service area.
Water quality depends on both the wholesaler's treatment standards and the condition of Halstead'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.

05Pressure on Halstead'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
3 facilities within 10 miles reported 0 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.
Flood & storm history
4 federal disaster declarations on record for Harvey County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Drought
Harvey County is in D1 (moderate 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.
