Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Jerome — it's the dominant profile. The median build year of 1987 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Jerome were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Jerome Homeowners
In Jerome, 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 Jerome are relatively low compared to home values. The $1,350–$3,900 estimated range is a small fraction of median property value. Home values are 24% below the Idaho average.
Lead Exposure Risk for Children in Jerome
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 Jerome have approached or crossed the regulatory action level on multiple occasions. Combined with 55% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Flood & Climate Risk in Jerome
The NFIP's multi-decade dataset for Jerome shows limited claims and limited zone coverage — a pattern that holds consistent implications for water quality. Flooding disrupts treatment systems and distribution infrastructure in proportion to event frequency, and environments with infrequent flood activity keep those disruption pathways largely dormant.
Jerome has a relatively low flood history with 1 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,500</strong> remediation cost per household.
