The groundwater in CT's aquifer 112DFSF, which supplies many residential wells, has been sampled by the U.S. Geological Survey. Water from this aquifer moves through underground layers before reaching your household taps. This page helps you decide on arsenic treatment by examining local sampling data and a documented treatment option for household water.
Regular Maintenance Rhythm for the Autotrol Arsenic Filter
The Autotrol Arsenic Filter ships ready to configure and operates with a maintenance rhythm adapted to residential use. It requires periodic checks to ensure filter media effectiveness and timely regeneration cycles, which restore filtering capacity. Household owners should note that the filter system does not demand complex upkeep but does involve routine attention to maintain arsenic removal performance over time.
What to Record Before Seeking Arsenic Treatment Advice
Before considering treatment options, note the following:
- Results from a recent, certified laboratory test of your own well water for arsenic levels.
- Known history of your water source, including well depth and construction details if available.
- Any prior water treatment equipment or processes used in your home.
- Water usage patterns to estimate daily volume requirements for treatment capacity.
These details enable tailored advice specific to your household’s water conditions.
How the Autotrol System Removes or Neutralizes Arsenic
The Autotrol Arsenic Filter employs a filtration media that adsorbs arsenic from water as it passes through. The system’s design supports regeneration cycles that restore the media’s capacity, ensuring consistent arsenic reduction. This process reduces arsenic concentrations from raw groundwater to levels that meet household water goals, addressing the arsenic measured in local samples with effectiveness designed for residential applications.
Differences Between Public System Records and Private Well Testing
Government sampling in aquifer 112DFSF shows arsenic detected in three samples from two wells with a median concentration of 0.15 micrograms per liter (µg/L) and a range from 0.1 to 0.16 µg/L. These samples, taken between 2011 and 2017 from wells 19 to 24 feet deep, represent area conditions rather than any single household well.
Public system records provide an overview of trends and typical concentrations in the aquifer but do not replace testing of your private well water. Private well testing establishes the precise arsenic level in your household water, which can differ from area medians due to local geology and well construction.
Consequences of Leaving Arsenic in Water Untreated
Long-term exposure to arsenic through drinking water is associated with health risks identified by health agencies, which have established maximum contaminant levels to guide safety. Although the local aquifer sampling shows arsenic well below federal limits, if your own water test reveals elevated levels, untreated arsenic can pose risks over many years.
Choosing appropriate treatment can help reduce potential exposure by lowering arsenic concentrations in your household water supply.
Interpreting the Measured Arsenic Range and Federal Standards
The detected arsenic range of 0.1 to 0.16 µg/L in local groundwater is below the U.S. Environmental Protection Agency’s maximum contaminant level for arsenic in drinking water. This means the sampled area’s groundwater is generally within regulatory safety guidelines. However, these measurements do not describe your well’s specific water quality and do not guarantee arsenic absence.
Testing your own water provides necessary information to assess treatment needs. The Autotrol Arsenic Filter is designed to address arsenic at levels that may be of concern, ensuring effective reduction if your water requires intervention.
Deciding on arsenic treatment for your household water involves understanding local groundwater data, carefully testing your well, and selecting a treatment that fits your water use and quality. The Autotrol Arsenic Filter offers a maintenance rhythm and filtration technology suited for residential arsenic reduction in CT's aquifer 112DFSF.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-09-06. 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 112DFSF aquifer (FIPS 170): 3 results from 2 wells, median 0.15 ug/L, range 0.1-0.16 ug/L; none above any federal threshold
