How Old Is Brewster's Housing Stock?
With 76% 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
Because the majority of Brewster's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1950 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Brewster were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Brewster: Remediation Cost in Perspective
What does remediation cost in financial context for Brewster homeowners? Proportionally very little — the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Brewster are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 26% below the Minnesota average.
Protecting Children from Lead in Brewster
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.
Routinely in Brewster, where 76% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
