How Old Is Hallam's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Hallam's residential inventory spans multiple construction eras, with the median build year of 2008 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
A significant portion of Hallam's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Hallam: Remediation Cost in Perspective
In Hallam, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Hallam are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 60% above the Nebraska average.
Protecting Children from Lead in Hallam
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.
Wherever 40% of local housing was built before solder rules changed — as is the case in Hallam — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Hallam
- 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 40% of homes built before 1986, lead solder is a real possibility.
