How Old Is Aurora's Housing Stock?
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
For a household in Aurora, a certified lab test of tap water answers what the median build year of 1992 cannot.
Most homes in Aurora were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Aurora
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.
Households with young children in Aurora have two area numbers to weigh. One is the mean of 90th-percentile lead values reported for local ZIP codes, which is at or above 0.010 mg/L; the other is the 39% share of housing that dates from before 1986. Neither describes one home, and sending a tap sample to an accredited laboratory is how a family measures its own lead level.

Historical Flood-Claim Evidence for Aurora
Historical NFIP data for Aurora contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,293. 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.
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.

What You Can Do in Aurora
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. Choose a pitcher or under-sink filter certified to reduce the specific contaminants of concern.
- Check your home's plumbing. With 39% of homes built before 1986, lead solder is a real possibility.
