When your water test report lists arsenic, it shows the concentration measured in micrograms per liter (ug/L or ppb) from your specific well water sample. To choose the right treatment, it helps to consider government sampling results from your area's aquifer, Lafayette Parish aquifer 112CHCTU, which provide context but do not state your exact water condition.

If you want to know how water looks at your tap after treatment

Using a Pentair Arsenic Filter system modifies your household water by reducing arsenic concentrations through proven filtration technology. While your untreated water arsenic level depends on your well, after treatment you can expect arsenic to be reduced significantly, improving water safety and compliance with arsenic standards. The treated water's arsenic concentration will depend on your initial levels and system configuration, but the Pentair system ships ready to configure for your household.

If you compare public water system records with private well results

Public water system records in Lafayette Parish generally report no health-based violations for arsenic. However, these records differ from private well testing because they reflect water treated and monitored before distribution, not raw well water. Private well results are the only way to confirm your home's specific arsenic concentration since regional data cannot predict your well water condition accurately.

If you evaluate the sample size and what it implies for local arsenic levels

The US Geological Survey collected 56 arsenic results from 31 wells in Lafayette Parish’s 112CHCTU aquifer between 2011 and 2021. These wells ranged from 11 to 250 feet deep. While this sample size offers a substantial snapshot of local groundwater arsenic, it cannot guarantee your particular well’s level. More samples increase confidence in the regional picture but individual wells can vary significantly from the median.

If you need to compare Lafayette Parish’s arsenic data with neighboring counties without overreading

Lafayette Parish’s median arsenic concentration in aquifer 112CHCTU is 1.3 ug/L, with a range from 0.18 to 26.9 ug/L, none exceeding federal arsenic thresholds. Neighboring counties may have different median or maximum arsenic values, but direct comparison should be cautious. Differences in geology, well depth, and sampling periods mean that contrasting data cannot precisely predict arsenic conditions across counties or your specific well.

If you want to understand terms like 'detected,' 'median,' and 'range' in this context

• Detected: all 56 samples showed measurable arsenic; none were below the reporting limit.
• Median: the middle value of the samples was 1.3 ug/L, indicating half the measurements were lower and half higher.
• Range: values spread from 0.18 ug/L to 26.9 ug/L, which shows the variability in arsenic levels across wells.

These terms describe what the USGS observed in this aquifer but do not indicate that any well exceeds safety thresholds. Detection means arsenic was present, not that it is unsafe.

The essential next step is to have your household water tested for arsenic by a certified laboratory to know your home's specific concentration. If your test shows arsenic above your comfort or regulatory levels, consider purchasing a Pentair Arsenic Filter system to reduce it effectively. Only your individual water test can settle the question of the treatment class you require.
