What does the detected selenium range mean compared to federal standards?
Water quality reports from U.S. Geological Survey sampling of wells in Palm Beach County's aquifer 110SAQS show selenium detected in every tested well, ranging from 0.04 to 13.5 micrograms per liter (µg/L), with a median of 0.2 µg/L. None of these samples exceeded federal drinking water standards for selenium. This means while selenium is measurable throughout the area, the concentrations found in these wells do not surpass regulatory health-based limits. However, detection indicates selenium is present in the environment, which may affect some households differently depending on local conditions.
How does selenium enter groundwater or the water supply in Palm Beach County?
Selenium commonly comes from natural geological sources where it is released from rocks and soils into groundwater, especially in shallow wells between 10 and 77 feet deep, like those sampled. Human activities such as agricultural runoff or industrial discharge can also contribute, but in this area, natural geochemistry is the primary factor. Selenium dissolves into the aquifer and can move with groundwater flow, eventually reaching household water sources depending on well depth and location.
What maintenance is required for the Pentair Heavy Metals Filter system?
The Pentair Heavy Metals Filter is designed to handle multiple water contaminants including selenium. It ships ready to configure for residential use. Regular maintenance involves monitoring filter performance and replacing filter media according to usage levels, water quality, and manufacturer guidelines. Proper upkeep ensures consistent removal efficiency and prolongs system lifespan without needing professional service arrangements.
How should the selenium record in Palm Beach County be compared with records from neighboring areas?
Comparing selenium levels between counties or aquifers must consider differences in geology, land use, and well characteristics. Neighboring counties may show different median concentrations or ranges based on these factors. Such regional data sets provide context but should not be used to infer exact conditions for individual wells. Variations underscore the importance of site-specific water testing rather than relying solely on area-wide reports.
How do public water system records differ from private well testing in what they establish?
Public water systems routinely monitor compliance with federal standards, reporting results for regulatory oversight. These data represent the treated distribution system and do not reflect raw water quality at the source. Private well owners must conduct independent laboratory testing to understand their own water quality, as local conditions can vary even within the same aquifer. Well testing is the only way to confirm specific contaminant levels for a household.
How does the Pentair Heavy Metals Filter remove or neutralize selenium?
The Pentair Heavy Metals Filter uses specialized media engineered to reduce selenium from water by adsorption and filtration mechanisms. This process captures dissolved selenium compounds, preventing them from reaching the tap. By effectively lowering selenium concentration, the system helps households manage this naturally occurring constituent, contributing to improved water clarity and quality.
What water test should I order to know my household's selenium level?
To determine selenium concentration in your water, request a certified laboratory analysis specifically for selenium. The report will list the exact concentration found in your sample. If the result is below or near the regional median, it aligns with area data. A result exceeding federal standards would indicate a need for enhanced treatment. Testing your own well supply is the definitive step to understanding your water's heavy metal content and deciding on the Pentair Heavy Metals Filter’s suitability.

Source: USGS groundwater sampling. Sampled 2016-08-22. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of Selenium in the 110SAQS aquifer (Palm Beach County): 32 results from 32 wells, median 0.2 ug/L, range 0.04-13.5 ug/L; none above any federal threshold
