What's in Apex's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Apex Infrastructure Age
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
The median home in Apex was built in 2006, after the federal ban on lead solder in plumbing. Most of the housing stock postdates that cutoff, placing typical plumbing risk on the lower end — though any home built before 1986 still warrants individual testing.
Most homes in Apex were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Apex
Given current Apex valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Apex are relatively low compared to home values. The $1,317–$3,200 estimated range is a small fraction of median property value. Home values are 110% above the North Carolina average.
Apex: 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.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Apex's pre-rule stock at 16% reflects a contained footprint.

Apex: Flood History & Water Damage Risk
How does Apex's flood record connect to local water quality? The NFIP documents 9 claims — enough to signal recurring events — and 100% of ZIP codes carry FEMA flood zone status. That combination places flooding in the category of factors that can periodically affect water infrastructure, even if the area isn't among the highest-exposure communities in the NFIP dataset.
Apex has a moderate flood history with 9 FEMA claims averaging $5,846 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>$2,067</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.
