Athol
What Athol filed with MassDEP about the water it produced and the water it billed for, 2019–2025 — and what the filing does and does not let anyone verify.
- Unaccounted-for water, FY2024
- 7.0% As accepted by MassDEP, which publishes this percentage and not the volumes behind it.
- unaccounted-for water, as accepted by MassDEP 7 sheet RGPCD UAW, cell O13
- Annual value of the filed loss
- — Not estimable from what MassDEP publishes. A loss percentage cannot be priced without the volume it is a share of.

Where this figure comes from
Read from data/archive/massdep/2026-08-11-7ed15002a7ec.xlsx (SHA-256 7ed15002a7ecc43d), our archived copy of the file as it stood on 2026-08-11. That path is committed to the repository and is not served here. The agency publishes its own current copy at https://www.mass.gov/doc/rgpcd-and-uaw-spreadsheet/download, which may since have been revised.
What the filing says
Athol serves an unreported number of retail connections. Municipal suppliers averaging 100,000 gallons a day or more calculate unaccounted-for water and residential gallons per capita per day in the Annual Statistical Report, and both are Water Management Act performance standards. MassDEP publishes those two percentages but not the volumes behind them, which is why this page carries no dollar figure. The volumes are in this system's own ASR filing.
What the record shows
7.0% unaccounted-for water in FY2024, higher than 19% of the 278 Massachusetts systems that filed that year.
- Above the 10% standard in 2 of 6 filed years.
- The figure is improving across the record.
- 1 of 7 years carry no figure — which by MassDEP's own note means it had insufficient data to calculate one.
It does not establish what moved. A meter replacement program, a main break, a change of billing system, a corrected prior-year filing and an ordinary reporting error all produce a series that looks like this, and a filed water loss audit does not say which happened. What the flag does say is that the years disagree with each other by more than most of the state's do, so a single year of this series is a weak basis for a decision without the records behind it.
Compliance record
5 violations on EPA's record for this system as of 2026Q2, of which 3 are health-based. 5 resolved, and 0 still open.
Nothing on the record is open as of 2026Q2.
Counted as distinct violations, not as rows: EPA's export carries one row per enforcement action taken against a violation, so a row count would multiply this system's record several times over. A violation here is a breach of a reporting, monitoring or contaminant-level rule as reported to EPA — it is not a measurement of the water, and this site has none.

| Year | Unaccounted-for water | Residential gal/capita/day |
|---|---|---|
| 2025 | 42.2 | |
| 2024 | 7.0% | 44 |
| 2023 | 4.0% | 43 |
| 2022 | 9.0% | 41 |
| 2021 | 4.0% | 41 |
| 2020 | 13.0% | 42 |
| 2019 | 28.0% |
Standards are 10% unaccounted-for water and 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.

Where is it going?
This page values the loss. It cannot say which accounts, which zones, or which meters, and it cannot say how much of that value is collectable. Answering either takes your billing history, your meter reads, and your production data reconciled against each other.
Our Water Loss Recovery Snapshot is three weeks, one flat fee, and the deliverable is a ranked list of specific accounts and zones with dollars and a confidence on each.

If a number here looks wrong, tell us: the error may be in the filing, in our reading of it, or in something the export does not show. Send a correction. We will check it against the source, correct the page where it is wrong, and say what changed.
