Key Contaminants Detected in Little Mountain
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Little Mountain's Housing Stock?
With 45% 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
A citywide median of 1982 for construction says little about any single address in Little Mountain. Homes built before 1986, when federal amendments restricted the lead content allowed in new pipe, solder and flux, may contain plumbing materials with more lead, and later renovations may have replaced them. An inspection of the plumbing can identify the materials, and sending a tap water sample to an accredited laboratory measures lead.
Most homes in Little Mountain were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Little Mountain: Remediation Cost in Perspective
Of the three cost-context tiers - low, moderate and elevated - Little Mountain is in the low one.

Protecting Children from Lead in Little Mountain
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
