Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Colton Infrastructure Age
With 49% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Over the decades, Colton accumulated housing from multiple construction periods. The median build year of 1983 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited — leaving a sizable share of homes on each side of that safety line.
Most homes in Colton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Colton
Low proportionality — that's the Colton picture when remediation costs are placed against typical home equity.
Remediation costs in Colton are relatively low compared to home values. The $150–$600 estimated range is a small fraction of median property value. Home values are 46% above the Oregon average.
Colton: Lead Risk & Vulnerable Populations
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 49% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Colton.
