The public water system serving Ridgefield in Fairfield County obtains its supply from surface water sources. This water goes through multiple treatment processes before reaching households, including codes 361, 363, 421, 445, 447, 680, 720, and 740, which correspond to various filtration and disinfection steps. The system serves over 7,400 people across nearly 2,800 connections.
Myth: Public water system data reflects individual well or tap water quality.
Government water quality records report system-wide findings, not specific to any one household’s water. Ridgefield’s public system data shows a lead concentration 90th percentile at 0.0031 mg/L, sampled at the distribution level—this reflects plumbing and household piping effects, not source water alone. To know your own tap’s water composition, individualized testing at your point of use is essential.
Myth: Water at the tap is identical to the treated water leaving the plant.
Although Ridgefield’s system applies several treatment methods to deliver safe water, water quality can change between the treatment plant and the tap due to pipe materials, age, and residence time. The Fleck Safe Drinking Water Filter, designed for residential use, further refines water right before household consumption, reducing contaminants and improving taste and clarity beyond municipal treatment.
Myth: Comparing Ridgefield’s water data directly with nearby counties reveals definitive safety differences.
Each water system draws from different sources and uses distinct treatment processes. While Ridgefield’s record shows one EPA health-based violation among seven total cases, this does not directly translate to safety levels compared to neighboring counties. Differences in sampling times, frequency, and system design mean comparisons require cautious interpretation to avoid overreading the data.
Myth: Terms like 'detected,' 'median,' and 'range' are synonymous with water safety limits.
Government reports list detected contaminants and concentrations measured across multiple samples. 'Detected' marks the presence of a substance but not its health risk. 'Median' is the middle value among samples, and 'range' shows variability. None of these alone establish that water is unsafe or requires treatment; they inform further inquiry.
Myth: Treatment capacity questions differ for households compared to commercial users.
While commercial and industrial operations may have specific demand or regulatory considerations, households primarily need to assess their daily water use volume against treatment system capacity. The Fleck Safe Drinking Water Filter ships ready to configure with residential flow rates suitable for average to large family usage, so household users can select a system aligned with their typical consumption.
For households in Ridgefield evaluating safe drinking water options, the most definitive step is to conduct a certified water test on your own tap water. Testing results will identify specific contaminants and concentrations unique to your home, enabling precise treatment decisions. This test result will guide whether a Fleck Safe Drinking Water Filter is appropriate to meet your household’s safe water needs.
