Water Source & Treatment

Where this water originates and how it's treated before reaching your tap.

Source
Groundwater
Drawn from underground aquifers via wells.

Source: Fall River Valley C.S.D. Consumer Confidence Report.

ZipCheckup is not affiliated with this water utility. Treatment and source data are sourced from the utility's published CCR filings.

Source water assessment from Fall River Valley C.S.D. Consumer Confidence Report:
A source water assessment was conducted in April 2002. Well 1-McArthur Well is considered vulnerable to agricultural drainage and non-irrigated crops. The well is also vulnerable to agricultural/irrigation wells. Arsenic is detected in the water supply and is believed to be associated with runoff from orchards, electronics production wastes, and erosion of natural deposits. Fluoride is detected and linked to natural deposits and fertilizer/aluminum factory discharge.

Treatment regime

How this utility classifies its treatment process and what each reported treatment chemical does.

Treatment classification
Minimal — disinfection only
Disinfection (typically chlorine) without additional filtration or coagulation stages. Common for groundwater systems where source water meets federal standards after disinfection alone.

Watershed exposure sources reported

Land-use and natural conditions identified in the utility's source-water assessment as potential contamination sources upstream of treatment.

Agricultural drainageNon-irrigated cropsAgricultural/irrigation wells

Treatment classification and chemical list sourced from Fall River Valley C.S.D. Consumer Confidence Report.

Treatment intensity is a ZipCheckup-derived classification based on the chemicals and processes the utility reports. Chemicals and contamination sources are taken verbatim from the utility's CCR filing. Routine federal monitoring and contaminant testing shown elsewhere on this page determine whether the water meets safety standards, not the treatment classification.

pH
7.8
How acidic or basic the water is on a 0-14 scale. Drinking water is typically near neutral.
EPA secondary range: 6.5 – 8.5
Fluoride
Not reported
Utility does not add fluoride
Measured fluoride concentration in parts per million.
Alkalinity
80 ppm CaCO₃
Capacity of the water to neutralize acids, expressed as calcium carbonate equivalent.
Total dissolved solids
