What 'Detected', 'Median', and 'Range' Mean in This Sampling Record
The U.S. Geological Survey collected groundwater samples from wells in Connecticut’s FIPS area 160, specifically aquifer 112DFSF. Across three wells sampled between 2011 and 2017 at depths ranging from 13 to 273 feet, iron was detected in 5 out of 6 results. The median value was 7.4 micrograms per liter (µg/L), with the range spanning from 0.136 to 11.4 µg/L. A detection means the measuring instruments found iron present; it does not indicate any violation of federal standards, as none of the results exceeded established federal thresholds for iron in drinking water in this dataset.
Interpreting Median and Range as a Homeowner
For a residential owner evaluating this data, the median iron concentration reported gives a central tendency of what was measured across multiple wells and times in your area. The range shows the variability you might expect within this sampling set. These values are not a direct measurement of your own well’s iron level but give a contextual background indicating iron is present but typically within low microgram-per-liter quantities in these local wells. To determine your household’s actual iron concentration, testing of your specific water is necessary.
Progressing from Basic Checks to Laboratory Testing
When sizing total well water treatment, start by confirming your household water flow rates and overall demand. Next, consider basic visual signs such as staining or discoloration in water fixtures that might suggest iron presence. Following that, conduct a certified laboratory test of your well water to accurately quantify iron and other constituents. This staged approach ensures treatment equipment capacity matches your actual water quality and volume needs without oversizing.
Adjusting for Large Households, Second, or Seasonal Homes
Homes with higher water usage or intermittent occupancy require attention to treatment capacity. Equipment with a grain capacity of 32,000 can handle considerable iron removal load, but in larger or seasonal households, water demand fluctuations should guide treatment sizing. For seasonal properties, equipment should be configured to manage intermittent water flow and potential stagnation effects. Planning treatment with these usage patterns in mind avoids undersizing or excessive resource consumption.
Sample Size and Its Impact on Data Reliability
The sampling behind this data comes from three wells and six total results collected over several years, providing a limited but informative dataset about aquifer 112DFSF in CT. While this small sample set indicates typical iron levels, localized conditions in an individual well might differ significantly. A homeowner’s own water test is essential for precise treatment sizing and confirming if iron levels align with area trends or present unique challenges.
Maintenance Rhythm of the C-Series Total Well Chlorination System
The C-Series Total Well Chlorination System, designed for comprehensive well water treatment, requires routine maintenance to sustain performance. Maintenance schedules depend on household water demand, but generally involve periodic system checks and replenishment of treatment media based on usage. This system ships ready to configure, enabling flexible setup tailored to your home’s size and water use patterns without extra assembly steps.
What Area Data Should Not Lead You to Assume
It is important not to use area-wide groundwater sampling data to infer the exact condition of your own well water. Detection and reported concentrations represent measurements across multiple wells and times but do not mean your well has the same iron level or water quality. Only a direct water test from your household supply can confirm specific treatment needs. Use area data as a preliminary context rather than a definitive guide for treatment sizing decisions.
