## Summary

Eastham reported **16.0% unaccounted-for water** in FY2024, above the Massachusetts standard of 10% and higher than 64% of the 278 systems that filed that year. For FY2025 MassDEP declined to publish an accepted figure, stating: "RGPCD not calculated for the Cape and Islands Basin."

## Filed history

| Year | Unaccounted-for water % | Residential gal/capita/day |
|---|---|---|
| 2025 |  |  |
| 2024 | **16** |  |

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.

The FY2024 loss figure: unaccounted-for water, as accepted by MassDEP at ` RGPCD UAW!O235` — in `data/archive/massdep/2026-08-11-7ed15002a7ec.xlsx` (sha256 7ed15002a7ecc43d, retrieved 2026-08-11, https://www.mass.gov/doc/rgpcd-and-uaw-spreadsheet/download), read by `src/scrape/ma.ts` at f29747387599.

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

## Compliance record

EPA's Safe Drinking Water Information System carries no violation for this system in the 2026Q2
download. That is a statement about the record: SDWIS completeness varies by primacy agency and by quarter, so
an empty record is not the same as a system that has never been in violation.
