Hanson Water Watch exists to make water quality information accessible to every household in town. The Water Department publishes a Consumer Confidence Report once a year, and MassDEP and EPA monitoring data trickles out on its own separate schedule — but none of it is written with an ordinary resident in mind.
We collect it, check it against state and federal guidelines, and put it in one place, in language anyone can read in five minutes.
This began with a handful of Hanson residents comparing notes after noticing manganese levels creeping up in the town's published testing data — not a scary contaminant by most measures, but a sign of just how closely Hanson's water is tied to the health of the aquifer underneath it. What started as a shared spreadsheet turned into this site: a standing effort to keep tabs on the Crystal Spring well system and flag anything worth a second look.
We track new MassDEP and EPA monitoring results as they're published, and compare them against the Water Department's own annual reporting.
A groundwater town has a different set of concerns than a surface-water one. We translate what a given mineral or compound level actually means for your household, without the jargon.
If you want a second opinion on your own tap water, we help connect residents with free testing and point toward locally relevant filtration options.
Hanson Water Watch is an independent, volunteer-run initiative. We are not affiliated with the Town of Hanson or the Hanson Water Department, and we don't speak on their behalf. Everything we publish links back to its original public source so you can verify it yourself.
