Key Contaminants Detected in Oakhurst
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Oakhurst's Housing Stock?
With 68% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
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. Oakhurst's median build year of 1971 places it squarely in that category.
Over half of homes in Oakhurst were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Oakhurst: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Oakhurst is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Oakhurst are relatively low compared to home values. The $1,500–$4,800 estimated range is a small fraction of median property value. Home values are 49% below the California average.
Protecting Children from Lead in Oakhurst
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.
Older stock in Oakhurst represents 68% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Climate-Related Water Risk for Oakhurst
Within the NFIP's national dataset, Oakhurst falls in moderate-exposure territory — 25 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Oakhurst has a moderate flood history with 25 FEMA claims averaging $22,437 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>$2,800</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.
