1. Understanding How Public-System Records Differ from Private-Well Testing
Water quality reports from public or shared groundwater sources like aquifers provide a general view of the area’s water but do not directly describe an individual household’s water. For Bristol County, MA, data from aquifer 112SRFD reflect samples from multiple wells and locations. These public records summarize chloride levels measured over time but do not replace a private well water test that specifically measures what flows into your home.
2. Reviewing the Number of Samples and Wells Behind the Chloride Figures
The chloride data for aquifer 112SRFD in Bristol County come from 14 samples taken across 7 separate wells. This sample size gives a baseline for chloride presence in the area’s groundwater but is relatively limited. Because variability can occur between wells and over time, this small sample set means individual conditions may differ.
3. Recording Key Information Before Seeking Treatment Advice
Before deciding on a water treatment approach, document your household’s water source type (private well or public supply), any known recent water tests with specific chloride or corrosivity reports, and the age and material of your plumbing. This information helps identify whether existing equipment is being challenged by your water quality and what features a treatment system should have.
4. Observing Seasonal and Multi-Year Chloride Variation in the Data
The chloride sampling dates span over nine years, from May 2010 to September 2019. The range of chloride concentrations in these samples went from 6.64 mg/L up to 236.0 mg/L, with a median of 68.4 mg/L. This variation shows that chloride levels can fluctuate, potentially affected by seasonal changes or other environmental factors. These fluctuations affect corrosivity, which can stress plumbing systems differently throughout the year.
5. Considering Sample Depth, Well Depth, and Source Type in Expectations
The sampled wells in this data set were between 20 and 66 feet deep. Well depth and water source affect the water's characteristics, including corrosivity. Shallow wells may have different mineral interactions than deeper ones. Knowing your well depth helps compare your water to the sampled data more accurately, but individual testing remains essential.
6. Interpreting What 'Detected,' 'Median,' and 'Range' Mean in This Chloride Record
All samples detected chloride, meaning instruments measured it in each sample. None of these results exceeded any federal health-based thresholds, so detection does not indicate unsafe water. The median reflects the midpoint value of the chloride measurements, giving a typical concentration found in the samples, while the range shows the lowest and highest measured levels over the collection period. These definitions clarify that the presence of chloride alone is not a cause for alarm but a factor in water’s corrosive potential.

This system ships ready to configure and is designed to address the effects of corrosive water, helping protect plumbing and extend equipment life based on the local demand demonstrated by measured chloride variation.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-09-18. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
