Housing Age Profile
For residents trying to assess tap water risk in Woronoco, the median build year of 1905 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Woronoco were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Woronoco: 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.
Before the federal solder ban, lead solder was a routine plumbing material, and 100% of the Woronoco inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Woronoco: Flood History & Water Damage Risk
Woronoco's NFIP record shows a low claim total — a pattern that keeps the link between flooding and water quality in the background rather than the foreground. Treatment infrastructure can be overloaded by severe flood events, but that scenario requires event frequency and magnitude that the area's claim history suggests have not materialized here.
Woronoco has a relatively low flood history with 1 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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>$1,600</strong> remediation cost per household.
