A laboratory report on total dissolved solids (TDS) in water from Lafayette Parish’s aquifer 112CHCTU lists concentrations measured in milligrams per liter (mg/L). The report’s values reflect individual sample results from a set of wells in the area, not your own well. These results show a range of TDS from 0.11 mg/L to 528.0 mg/L with a median of 155.0 mg/L over 168 samples collected from 31 wells between 2011 and 2021. One sample was below detection limits. Two results exceeded the secondary aesthetic guideline of 500 mg/L, which relates only to taste and staining concerns, not health.
If you consider the sample depth, well depth, or source type
Samples in Lafayette Parish came from wells drilled between 11 and 250 feet deep. The well depth affects what concentrations to expect because water quality can vary by underground strata and flow patterns. A shallower well might have different dissolved solids compared to a deeper well drawing water from a distinct zone in the aquifer. Your own well’s depth and construction will affect whether these regional values are a rough guide or less applicable. Source type also matters: a groundwater source like a well differs from surface water in typical dissolved solids levels and variability.
If you want to rule out causes for complete well water problems in the right order
- Start with visual and mechanical checks: ensure physical components such as pumps and pressure tanks are working properly.
- Test for common readily detectable issues: turbidity, odors, coloration that might indicate contamination or mechanical failure separate from dissolved solids.
- Obtain professional laboratory testing specifically for total dissolved solids and other relevant constituents in your well water to identify actual concentrations.
If you consider questions a commercial or industrial operator adds but are less relevant for your household
Commercial and industrial operations typically require additional water quality parameters to assess compliance and process impact, such as detailed inorganic profiles, organics, or specific ionic strengths. They also evaluate flow rates, pressure stability, and equipment compatibility on a larger scale. As a household, focusing on essential water quality parameters like total dissolved solids, pH, and basic microbiological safety is usually enough to determine treatment needs.
If you want to match treatment capacity to your household’s daily water use
Estimating daily water consumption is key to selecting an appropriate treatment system. The Autotrol Complete Well System offers a grain capacity of 32,000, which indicates how much total dissolved solids it can address before requiring regeneration or maintenance. For an average household, this capacity is sufficient to handle typical water usage and dissolved solids load based on Lafayette Parish water quality data, ensuring consistent treatment performance.
If your household is large, a second home, or used seasonally
Larger households or multiple residents increase daily water consumption, which may require a larger capacity or multiple treatment units to maintain performance. For seasonal properties or second homes, consider periods of inactivity when sizing the system and planning maintenance. Ensuring the treatment system can adjust to fluctuating demand helps preserve water quality and equipment longevity.
In summary, Lafayette Parish’s aquifer 112CHCTU water data reflect regional groundwater quality from wells 11 to 250 feet deep sampled over a decade. These figures serve as a guide rather than a direct measure of your well’s condition. To accurately understand your water, specific laboratory testing of your well is needed. The Autotrol Complete Well System ships ready to configure, providing a 32,000 grain capacity treatment solution suitable to typical household demands in this area.
