What's in North Highlands's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
North Highlands Infrastructure Age
With 83% 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
When a city's housing median build year is 1963, as in North Highlands, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in North Highlands were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in North Highlands
In North Highlands, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in North Highlands are relatively low compared to home values. The $1,200–$2,600 estimated range is a small fraction of median property value. Home values are 55% below the California average.
North Highlands: Lead Risk & Vulnerable Populations
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 North Highlands represents 83% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

North Highlands: Flood History & Water Damage Risk
Flood risk in North Highlands occupies the middle ground: 34 NFIP claims and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.
North Highlands has a moderate flood history with 34 FEMA claims averaging $5,384 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>$1,800</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.
