Understanding your water, in plain language

A few explainers on the topics that come up most often when neighbors reach out to us.

Why a mixed supply matters

Most South Shore towns draw from one dominant water source. Scituate draws from six wells, two surface reservoirs, and a cross-town agreement with Marshfield — which means water quality can genuinely vary more by neighborhood than in a single-source system.

Reading a CCR

Your annual Consumer Confidence Report lists every contaminant tested, the range detected, and the legal limit. Pay attention to the health-based goal column too — it's often stricter than the legal limit, and it's the number that matters for long-term exposure.

Total Coliform Rule, explained

A Total Coliform Rule violation means routine bacteria monitoring found an issue — it's a process/monitoring flag, not automatically evidence of an ongoing health risk, but it is the kind of thing worth understanding if it shows up in a system's history.

Should you filter your water?

Public data on Scituate's PFAS levels currently looks reassuring, but a mixed-source system means household-level variation is real. Meeting legal limits system-wide doesn't guarantee every tap in town tastes or tests the same.

Activated carbon filtration

Effective against chlorine taste and odor, many disinfection byproducts, and some PFAS compounds, depending on the specific carbon media and contact time.

Reverse osmosis

The most thorough option for PFAS, nitrates, and a broad range of dissolved contaminants. Typically installed under a kitchen sink for drinking and cooking water.

Not sure where to start?

A free household water test is the easiest way to figure out whether filtration makes sense for your specific home, and if so, which approach fits.
