Housing & Infrastructure in Callaway
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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Callaway, the median build year of 1997 indicates that plumbing age is a material factor in local lead risk - with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Callaway were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Callaway Homeowners
In Callaway, the equity impact of remediation is proportionally small - not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Callaway are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 14% below the Maryland average.
Lead Exposure Risk for Children in Callaway
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Callaway have approached or crossed the regulatory action level on multiple occasions. Combined with 34% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.
