Housing Age Profile

When a city's housing median build year is 1984, as in Maple Falls, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.

Over half of homes in Maple Falls were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

0.0015
mg/L Avg Lead (Limit: 0.015)

Older stock in Maple Falls represents 50% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.
