Area Groundwater Sampling: What Lafayette Parish Data Shows
The U.S. Geological Survey conducted groundwater sampling across Lafayette Parish, focusing on aquifer 112CHCTU. Over a decade (2011 to 2021), 56 manganese measurements were taken from 31 separate wells situated between 11 and 250 feet deep. Every detection reported manganese presence, with values ranging from as low as 0.39 micrograms per liter to as high as 2,120 micrograms per liter. Importantly, none of these figures exceeded any federal threshold for health-based water quality standards.
Sample Size and Statistical Weight: What the Measurements Represent
These 56 results represent a moderate sample size spread over multiple wells, offering a regional snapshot rather than a household-specific reading. While a well-tested laboratory test is necessary to understand the manganese concentration in your own home’s water supply, these data provide evidence of manganese presence in the region’s groundwater sources. The median manganese value of 273 micrograms per liter signals a common occurrence, but individual wells—yours included—may vary substantially.
How the Pentair Metallic-Tasting Water Filter Works on Manganese
The Pentair Metallic-Tasting Water Filter is designed to reduce manganese and related metallic taste contributors from water in residential settings. This system uses proven filtration technology to target manganese compounds responsible for metallic flavors, helping improve the taste and clarity of household water. It ships ready to configure, allowing for straightforward integration with existing equipment that may currently be unable to handle manganese at the concentrations found in Lafayette Parish.
Sources of Manganese in Groundwater of Lafayette Parish
Manganese naturally occurs in soils and geological formations. In Lafayette Parish, aquifer 112CHCTU taps into underground layers where manganese leaches into water over time. Factors such as the depth of a well and local geology influence concentrations. Additionally, water movement through the aquifer can carry dissolved manganese into wells and, ultimately, residential supply lines. This process is distinct from household plumbing conditions or distribution system treatments but affects the water quality reaching your home.
Interpreting Local Area Data: A Worked Example
The median manganese level of 273 micrograms per liter means that half of the samples had concentrations below this value and half above. Because the range extends to over 2,000 micrograms per liter, this indicates variability among wells in Lafayette Parish. If your household water exhibits a metallic taste, it may be related to manganese levels similar to those detected here. By testing your own water, you can determine your specific manganese concentration, which informs treatment decisions. The Pentair Metallic-Tasting Water Filter can then be chosen appropriately to address your household’s needs.
Comparing Lafayette Parish with Neighboring Areas
When looking at reports from neighboring parishes or counties, bear in mind that manganese levels can vary widely due to differences in geology and water sources. The presence of manganese in Lafayette Parish wells does not directly predict levels elsewhere, nor does it imply that all regional water systems share the same manganese profile. Use each area’s government sampling records as a guide, not a guarantee, of local water quality characteristics.
What Area Sampling Does Not Reveal
Data from groundwater sampling in Lafayette Parish provide valuable regional insights but do not indicate the condition of your specific well or tap water. Detection of manganese in this area is not a safety concern by itself and should not be assumed to imply any violation of water quality standards. To understand your household water quality and whether manganese is causing a metallic taste, a laboratory test of your own water supply is essential. Armed with those results, the Pentair Metallic-Tasting Water Filter offers a documented solution that ships ready to configure for residential use.
