Riverdale Infrastructure Age
With 42% 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
Riverdale's residential inventory spans multiple construction eras, with the median build year of 1993 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints - a plumbing practice banned that year - while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
A significant portion of Riverdale's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

How Remediation Costs Compare in Riverdale
Remediation costs in Riverdale are small relative to typical property values - the cost-to-value ratio here is favorable.
Remediation costs in Riverdale are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 21% below the New Jersey average.
Riverdale: 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.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 42% of Riverdale stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

Riverdale: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Riverdale contains 117 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,335. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
