Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Tatitlek's Housing Stock?
With 55% 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.

Housing Age Profile
While newer cities carry lower aggregate plumbing risk from lead-era construction, Tatitlek sits firmly in the older category. The median build year of 1985 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing — and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in Tatitlek were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Tatitlek
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.
Before the federal action against lead-bearing solder, that material was routinely permitted in new plumbing — and 55% of Tatitlek housing dates from that earlier era. Citywide utility samples have also moved past the regulatory action level. Two independent indicators are aligned here: a majority of buildings carry pre-rule interior lines, while system-level concentrations sit beyond the federal benchmark. Households with kids or pregnant residents can find an in-home test and a certified lead-removal filter through certified retail channels.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
