If you see reported arsenic values in Hampden County aquifer 112SRFD, what does that mean?

The U.S. Geological Survey’s sampling from 2011 to 2017 across 10 wells in Hampden County’s aquifer 112SRFD detected arsenic in some cases, with recorded results ranging from 0.06 to 6.5 micrograms per liter (ug/L) and a median of 0.09 ug/L. None of these values exceeded federal safety thresholds for arsenic concentration in drinking water. This means the sampled water overall meets federal health-based standards during this period. However, a detection of arsenic is simply a measurement of presence, not an indication of a violation or immediate health risk.

If you consider these government samples, how confident can you be that they represent your household water?

The data comes from a limited set of 14 samples taken from 10 wells over nearly six years. While it provides a regional snapshot of arsenic presence in the aquifer, individual household wells can vary widely due to local geology, well depth, and construction. The relatively small number of samples means these results should be viewed as indicative of the area’s groundwater but not as definitive for any single water source. To know your household’s specific arsenic level, actual testing of your own water is the only reliable method.

If your well taps aquifer 112SRFD at varying depths, how might arsenic levels differ?

The sampled wells ranged from 8 to 141 feet deep, showing some variation in arsenic concentrations. It is common for deeper or shallower wells to have different water quality due to geological layers and mineral content variability. Therefore, the arsenic concentration in your water may differ from the regional samples depending on your well’s depth or the exact location within the aquifer. Depth and source type are key factors influencing arsenic presence and require individual analysis.

If you’re concerned about water taste or appearance, how do arsenic standards relate to these concerns?

Arsenic is regulated by enforceable federal health standards to protect against long-term exposure risks. Unlike some other constituents, arsenic does not generally cause aesthetic issues such as taste or staining in household water. The federal standard for arsenic is health-based and differs from secondary standards that address aesthetic or corrosivity concerns. Detecting arsenic below federal limits does not impact water’s flavor or appearance but relates to health safety over extended exposure.

If you want to evaluate treatment options, what should you document before proceeding?

Before considering water treatment for arsenic, first obtain a current, certified laboratory analysis of your household water’s arsenic concentration. Note your well depth, source type, and any relevant historical testing information. This information is essential to determine whether treatment is needed and to select an appropriate system. The Autotrol Arsenic Filter system offers a documented approach to reduce arsenic levels if your water tests above desired thresholds. It ships ready to configure for household use and can be integrated into your water supply system based on your specific water quality data.

In summary, the U.S. Geological Survey’s record for Hampden County aquifer 112SRFD covers arsenic measurements from 10 wells sampled over several years, showing detections well below federal limits but not representative of all wells or household water. Confirming your own water quality through testing is the only way to understand your exposure and treatment needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-08-10. 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.

On record: U.S. Geological Survey sampling of Arsenic in the 112SRFD aquifer (Hampden County): 14 results from 10 wells, median 0.09 ug/L, range 0.06-6.5 ug/L; none above any federal threshold
