Residents of Bristol, Farmington, Plainville, and Southington in Hartford County receive their water from the AQUARION-PLAINVILLE REGIONAL public groundwater system. Water is drawn from underground sources and then treated using various processes before reaching taps in approximately 6,622 homes. This process influences the quality of water residents drink daily.
If you notice household symptoms like unusual tastes or cloudiness
Some water issues manifest clearly, but many do not. For example, if drinking water has a strange taste, appearance, or causes discomfort, this might indicate that certain constituents in the water warrant attention. However, symptoms such as dryness of the skin or other unrelated conditions usually do not signal unsafe drinking water. It's important to distinguish signs linked directly to water quality to assess the need for home water treatment effectively.
If your household is large, a second residence, or a seasonal property
Water needs and concerns can differ notably with household size or usage patterns. Large families or frequent guests increase daily water consumption, requiring treatment options capable of handling higher volumes. Second homes or seasonal properties might experience irregular water use, which can affect water freshness and require distinct management strategies. These factors influence the selection and configuration of any water treatment system.
If you observe water constituent levels near or exceeding aesthetic secondary standards
The AQUARION-PLAINVILLE REGIONAL system maintains compliance with EPA health-based limits, with one health-based violation recorded out of sixteen total. For instance, lead measured in the distribution system shows a 90th percentile at 0 mg/L, indicating very low concentrations in tap water plumbing, not source water. Secondary standards govern characteristics like taste, staining, or corrosivity but are not health safety limits. Exceeding these aesthetic levels does not imply unsafe water but could influence household preferences and treatment choices.
If you operate a commercial or industrial property considering water treatment
Commercial and industrial users add layers of complexity, such as higher water volumes and specific process requirements. They may also need to comply with different regulations or quality standards than residential users. These factors lead to unique treatment demands beyond those typical for households, requiring tailored solutions and professional assessments.
If you have a certified laboratory report for your drinking water
A certified laboratory test provides a snapshot of your home's water quality, identifying concentrations of various constituents. Such reports help distinguish between the characteristics of the public water supply and any issues introduced by plumbing or household fixtures. Understanding these results clarifies what treatment steps might be necessary. Testing is the only way to determine the specific quality of your water, as system-wide data reflects averages and does not guarantee individual household conditions.
