What's in Glendale Heights's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Glendale Heights Infrastructure Age
With 74% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in older housing is tied to the period before 1986, when lead pipes and lead solder were still permitted in new plumbing. Glendale Heights's median build year is 1973, and properties from before that year might still contain lead-bearing joints or pipes. Much of that risk sits inside individual properties, which city-level water quality averages don't capture.
Over half of homes in Glendale Heights were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Glendale Heights: 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.
Two pieces of area data frame lead for Glendale Heights families. First, the average of ZIP-level 90th-percentile lead results is 0.010 mg/L or higher. Second, census figures put homes built before 1986, which are more likely to contain lead pipes, fixtures or solder, at about 74% of the housing stock. Neither figure measures a particular home, so a certified lab test of the tap water is the step that shows the lead level there.
