How Old Is Hidalgo's Housing Stock?
With 50% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Hidalgo's median build year of 1983 places it squarely in that category.
Over half of homes in Hidalgo were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hidalgo: Remediation Cost in Perspective
In Hidalgo, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Hidalgo are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 49% above the Illinois average.
Protecting Children from Lead in Hidalgo
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 50% pre-rule share in Hidalgo keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

What You Can Do in Hidalgo
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 50% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
