Throughout Frisco and across its water systems, EPA compliance data for TX shows above-average performance - violations are minimal, none of the tracked systems have recorded repeated MCL exceedances in recent cycles, and the safety picture has held steady across multiple reporting periods.

Data: EPA SDWIS

Overview

We track home safety data for 3 ZIP codes in Frisco, Texas (population ~187,486), covering 5 community water systems serving approximately 545,299 people region-wide. The EPA snapshots used for this build directly map water systems to 3 of 3 ZIP codes.

3 of 3 ZIP codes with a reported violation count in the available EPA record (100%) have recorded EPA violations. The available record reports no health-based violations for this measured scope.

Home Safety Score

Average Home Safety Score for Frisco: A (98/100)

Model 4.0.0 uses four measured components across three equally weighted domains. If a required domain is unavailable, no score is published:

Factor	What It Measures
Water Quality	EPA violations and compliance history
PFAS MCL Screen	UCMR 5 testing against the covered federal MCLs
Radon Risk	EPA radon zone classification
Annual AQI	EPA AirData county-year median with at least 90 observed days

Housing Age Profile

Lead exposure in tap water isn't just a function of what water utilities deliver - it's also shaped by the plumbing inside individual homes. Structures built before 1986 may contain lead-soldered copper joints, and homes built before 1970 face an additional risk from lead pipes themselves. Frisco's median build year of 2002 suggests the housing stock is broadly weighted toward the safer post-1986 era, but the age distribution shown above makes clear that the pre-1986 share of the inventory still represents a meaningful fraction worth understanding for anyone in an older home.

Most homes in Frisco were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Frisco

How much of a Frisco home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.

Remediation as % of home value 0.3%

Remediation costs in Frisco are relatively low compared to home values. The $1,233–$2,833 estimated range is a small fraction of median property value. Home values are 166% above the Texas average.

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.

Reading aggregate data alone gives a clean picture for Frisco - system samples below the federal action mark and 5% pre-rule housing - yet that math averages many service connections. A one-tap draw gives the only direct read for a specific home.

Frisco: NFIP Claim Records and Water-Quality Context

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

0%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Frisco contains 25 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $37,976. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

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. The <strong>$1,900</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
