Housing & Infrastructure in Caliente
With 44% 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
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Caliente's median build year of 1982 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Caliente were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Caliente Homeowners
In Caliente, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Caliente are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 64% below the California average.
Lead Exposure Risk for Children in Caliente
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 44% pre-rule share in Caliente keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Flood & Climate Risk in Caliente
Over the multi-decade window covered by the National Flood Insurance Program, Caliente has accumulated 5 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Caliente has a moderate flood history with 5 FEMA claims averaging $19,499 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,600</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
