## Summary



## Filed history

| Year | Unaccounted-for water % | Residential gal/capita/day |
|---|---|---|
| 2025 |  | 53 |

| 2023 |  | 50.8 |
| 2022 |  | 52 |

Bold is above the Massachusetts standard — 10% unaccounted-for water, 65 gallons per
capita per day. A blank is a year MassDEP could not calculate a value: by its own note, a system not fully metered, a master
meter malfunction, seasonal population, or no report filed.

MassDEP publishes these as percentages rather than volumes, so no dollar figure is derivable from this source. The volumes are in this system's own Annual Statistical Report.

Figures are as filed unless stated otherwise. If a number here is wrong it is wrong in the filing or wrong in
our reading of it, and both are worth knowing: ammar@municorn.us

against a violation. A violation is a breach of a reporting, monitoring or contaminant-level rule as reported
to EPA; it is not a measurement of the water.
