What's in Mckinney's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Mckinney Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Federal restrictions on lead pipe, solder and flux in new drinking water plumbing date from the 1986 Safe Drinking Water Act amendments; the median build year of 1998 for Mckinney is one reference point against that date.
Most homes in Mckinney were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Mckinney: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Roughly 16% of homes in Mckinney were built before 1986, when federal law restricted lead in new plumbing.

Mckinney: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Mckinney contains 50 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $24,816. Among ZIP codes with claim records, 67% 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 $600 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.
