How Old Is Mount Holly's Housing Stock?
With 58% 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
Pre-1986 plumbing is not a rare legacy case in Mount Holly — it's the dominant profile. The median build year of 1988 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Mount Holly were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mount Holly: Remediation Cost in Perspective
Because property values in Mount Holly comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Mount Holly are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 40% below the New Jersey average.
Protecting Children from Lead in Mount Holly
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.
58% — that captures the slice of Mount Holly housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Climate-Related Water Risk for Mount Holly
How does Mount Holly's flood record connect to local water quality? The NFIP documents 270 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.
Mount Holly has a moderate flood history with 270 FEMA claims averaging $14,630 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>$2,200</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.
