Haskell Water: The Quick Version
- Your city's water systems recorded 23 violations in the past 5 years.
- Average lead level: 0.0026 mg/L.
- Homes built before 1986: 55% — older plumbing may contain lead solder.
- Estimated remediation: $3,700 per household.
- CDC health risk index: 13.54 — above typical levels.
Water Systems Serving Haskell
Residential water in Haskell, OK is supplied by 3 separate utilities — not one centralized authority. Each of those providers operates under its own service territory boundary, maintains its own distribution infrastructure, and files compliance documentation with the EPA on its own timeline. Federal data counts 9 water systems in the area, with these providers collectively accounting for the dominant share of household connections.
Overview
We track water quality and home safety data for 1 ZIP code in Haskell, Oklahoma (population ~4,831), covering 9 community water systems serving approximately 41,090 people region-wide.
1 of 1 ZIP code (100%) have recorded EPA violations. 18 health-based violations documented.
Home Safety Score
Average Home Safety Score for Haskell: B (70/100)
The score combines three factors:
| Factor | What It Measures |
|---|---|
| Water Quality | EPA violations and compliance history |
| Lead Levels | 90th percentile lead concentration vs EPA action level |
| Radon Risk | EPA radon zone classification |
Water Sources
Haskell water systems draw from: Groundwater, Surface water.
Lead & Copper
- Average lead level (90th percentile): 0.0026 mg/L (EPA action level: 0.015 mg/L)
- 0 ZIP codes exceed the EPA lead action level
Radon Risk
Dominant radon zone: Zone 3 (Low Risk)

How Old Is Haskell's Housing Stock?
With 55% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1970 places Haskell's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Haskell were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Haskell: Remediation Cost in Perspective
Cost-to-value data for Haskell produces a high remediation-share classification — the equity impact here is elevated, placing this market in the tier where financial preparation is a meaningful factor in how homeowners approach documented issues.
At 2.4% of home value, remediation costs in Haskell represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,500–$6,300. Home values here are 5% above the Oklahoma average.
Protecting Children from Lead in Haskell
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Locally, 55% of Haskell homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Climate-Related Water Risk for Haskell
Although Haskell's flood history doesn't reach high-severity thresholds, NFIP data documents 5 claims and FEMA maps place 100% of ZIP codes in designated flood zones — a combined profile that makes flood-related water quality considerations a reasonable planning baseline.
Haskell has a moderate flood history with 5 FEMA claims averaging $64,512 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$3,700</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
