Real EPA measurements of radium for Massachusetts water systems — Six-Year Review compliance samples 2012–2019 (historical). Methodology
EPA does not publish per-city radium measurements for Massachusetts in the datasets we use, so this section shows what regulators actually recorded: every Safe Drinking Water Act violation tied to radium at the 47 Massachusetts public water systems we track, since 2016. Source: EPA SDWIS via ECHO (2026 Q2 extract).
No radium violations on record. None of the 47 tracked Massachusetts systems has a SDWIS violation for radium since 2016. That means no monitoring, reporting or limit violation was logged — it is not a lab result for your tap. Check your utility's annual Consumer Confidence Report for measured levels.
Every Massachusetts system with a radium result in EPA's data, sorted by level. Averages of 2012–2019 finished-water samples, non-detects counted as zero — historical, not today's tap.
No radium detections have been reported in Massachusetts cities.
Radium is a radioactive element that accumulates in bones and can cause bone cancer. Long-term exposure increases risk of bone cancer and may also increase risk of leukemia. Radium behaves similarly to calcium, so it deposits in bones and teeth where it continues to emit radiation, damaging bone marrow.
Erosion of natural deposits; found naturally in groundwater, especially in certain geologic formations
Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,radium has been detected in 0 Massachusetts water systems.
The EPA MCL for combined radium-226 and radium-228 is 5 pCi/L. The EPA MCL for radium is 5 pCi/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
0 Massachusetts cities have radium detected in their water supply. All tested cities are within EPA safety limits.
Increased risk of bone cancer and leukemia from long-term exposure. The most vulnerable groups include growing children and pregnant women.
The most effective methods for removing radium include Ion Exchange (Water Softening), Reverse Osmosis, Lime Softening. Look for filters certified by NSF/ANSI for radium reduction.
The EPA Maximum Contaminant Level (MCL) for radium is 5 pCi/L.The EPA MCL for combined radium-226 and radium-228 is 5 pCi/L.
This page shows what Massachusetts utilities reported for radium. It cannot tell you what is coming out of your own tap: utility samples are taken across a whole system and averaged, levels vary by address and season, and anything picked up after the water leaves the main never appears in their report.
