Update 2026-04-10 (PST) (AI summary of creator comment): The creator has clarified how "2025" data will be interpreted for resolution:
Cambridge's annual water quality reports are published by July 1 each year, but reflect the prior year's data (e.g., the report published in June 2025 covers 2024 water data)
2025 calendar-year water data is not yet available in any posted annual PDF
If resolving based on the report published in 2025 (covering 2024 data): results are mixed — Total Haloacetic Acids rose slightly (8.06 → 8.3 ppb), but Total Trihalomethanes fell (11.8 → 11.2 ppb)
The market will likely wait for actual 2025 water data, expected in a report published around mid-2026
1,000"I checked the Cambridge PDF reports. The annoying municipal wrinkle is that the PDF published in 2025 is not “2025 water data.” Cambridge says these annual consumer-confidence reports are due by July 1 each year, and the city’s water-quality page currently lists the 2024 and 2023 annual reports. The latest posted PDF was distributed in June 2025 and is labeled “Water Quality Information From 2024”; the previous one was distributed in June 2024 and is labeled “Water Quality Information From 2023.” So from the annual PDFs alone, there is not yet a posted annual PDF for 2025 water-quality data.
If by “2025” you mean the report published in 2025, then DBPs were mixed, not simply higher. In the 2025-issued report, Total Haloacetic Acids were 8.3 ppb, up slightly from 8.06 ppb in the prior report. But Total Trihalomethanes were 11.2 ppb, down from 11.8 ppb. Both were still well below the listed limits of 60 ppb for haloacetic acids and 80 ppb for trihalomethanes.
So the clean answer is: from the posted PDF reports, no clear overall increase. One DBP group went up a hair, the other went down. If you meant actual calendar-year 2025 DBPs, those are not in the posted annual PDFs yet."
