1. What Well Depth and Source Type Mean for Iron Levels in Aquifer 112DFSF
Water in Connecticut's aquifer 112DFSF, which supplies many residential wells, is drawn from depths ranging from shallow to several hundred feet underground. Government groundwater samples in this area come from wells between 13 and 273 feet deep. Water drawn from different depths can carry differing amounts of iron, which may influence the presence and activity of iron bacteria in home water. Recognizing that deeper wells may encounter water with varying iron concentrations helps set realistic expectations for treatment needs.
2. Significance of Limited Sample Size from Local Wells
The iron data for this area comes from six measurements taken across three separate wells over a six-year period. This relatively small number of samples means the reported range and median iron levels provide a snapshot, not a full account, of all possible conditions in the aquifer. While five out of six samples detected iron, one was below the reporting limit. Such limited data suggest variability in iron concentration that homeowners should consider when evaluating their water quality.
3. Interpreting Certified Lab Tests for Iron in Your Water
Professional water tests report iron concentration typically in micrograms per liter (ug/L). For aquifer 112DFSF, median iron concentration was 7.4 ug/L, with a range from 0.136 to 11.4 ug/L. These values fall below any federal regulatory thresholds for iron, indicating no official water quality violations. However, iron’s presence—even at non-violative levels—can support iron bacteria growth, which impacts water aesthetics and plumbing performance.
4. How the Fleck Iron Bacteria & Slime Filter Treats Iron Bacteria
The Fleck Iron Bacteria & Slime Filter is designed to target and reduce iron bacteria and associated slime in residential water systems. Utilizing filtration technology specifically tailored to capture iron bacteria colonies and suspended iron particles, this system neutralizes the bacterial growth that existing equipment might not fully control. It ships ready to configure for home water lines, enhancing ongoing water quality management where previous treatments fall short.
5. Changes in Water Quality You May Notice After Treatment
When the Fleck system operates effectively, users can expect a reduction in water staining on fixtures and laundry, less slime buildup in pipes and tanks, and a clearer appearance to the water. While the treatment does not alter iron concentrations directly reported in lab results, the reduction of iron bacteria improves water usability and appliance longevity by limiting bacterial growth and its effects.
6. Additional Concerns for Commercial Operators Versus Residential Households
Commercial water users often confront larger volumes and additional regulatory requirements compared to households. While residential treatment focuses on comfort and aesthetics, commercial operations may need to consider ongoing microbial monitoring, system capacity, and compliance with industry-specific regulations. Residential users generally benefit from straightforward filtration solutions like the documented Fleck system without the scale or complexity of commercial water management.
The iron measurements described are from U.S. Geological Survey groundwater samples in Connecticut's aquifer 112DFSF, reflecting data from a limited number of wells sampled over several years. For details and updates, refer to the original government source at the USGS website.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-09-08. 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 Iron in the 112DFSF aquifer (FIPS 160): 6 results from 3 wells, median 7.4 ug/L, range 0.136-11.4 ug/L; none above any federal threshold
