What should you note before seeking treatment advice for uranium and radium?

Before considering any water treatment option for uranium or radium, record details about your household water system and any water quality testing you've had done. This includes any test results for uranium or radium specific to your well or tap. Area data cannot replace a direct test of your water. Also note your household water usage patterns, the depth of your well if known, and any visual or taste issues you've noticed.

How many samples support the uranium findings in Lee County's aquifer 230SDMR?

The U.S. Geological Survey sampled groundwater from nine separate wells in Lee County's 230SDMR aquifer from May to June 2012. Each well was between 100 and 325 feet deep. All nine detected uranium, with concentrations ranging from 0.014 to 2.19 micrograms per liter and a median of 0.518 micrograms per liter. These results show the presence of uranium in the area aquifer but reflect only a small number of wells and a specific timeframe, so they provide an overview rather than a complete picture. They do not represent uranium levels in any single household’s water.

How often should maintenance be performed on a uranium and radium treatment system?

The Pentair Uranium & Radium System ships ready to configure and generally requires periodic maintenance based on its grain capacity, which is 32,000 grains. Maintenance typically involves replacing or regenerating the filtration media according to the manufacturer’s guidelines to ensure continued effectiveness against uranium and radium. The frequency depends on your household’s uranium levels, water usage, and system settings. Regular water testing is recommended to determine when maintenance is needed.

How do you determine if treatment capacity fits your household's daily water demand?

Treatment capacity should be matched to your daily water usage and the concentration of uranium and radium in your water. The documented system’s 32,000 grain capacity reflects the amount of contaminants it can capture before maintenance is needed. Higher daily water use or higher uranium and radium levels will consume this capacity faster. Estimating your average daily water volume helps you plan maintenance intervals and ensures the system continues to operate effectively without premature exhaustion of its media.

What does the median and range of uranium levels mean for a homeowner in Lee County?

The median uranium level in the sampled wells is 0.518 micrograms per liter, while the range goes as low as 0.014 and as high as 2.19 micrograms per liter. This means that while uranium is consistently present in the aquifer, its concentration varies across locations. As a homeowner, knowing your well water’s uranium level through direct testing is crucial because your water could fall anywhere within or outside this range. The data helps you understand local background levels but is not a substitute for your own water quality results.

What does the data say about uranium levels relative to federal guidelines?

None of the tested wells from the Lee County aquifer exceeded the United States federal uranium standard. This standard is a health-based guideline for uranium concentration in drinking water. Although uranium was detected in all samples, the detected levels were below regulatory limits. This indicates no federal health violations were found in this dataset. However, these measurements do not guarantee that every well in the area meets this standard; only local testing can establish compliance for your household water.

What should you not conclude from these area-wide uranium data?

Area uranium data do not reveal actual uranium levels in your home’s water supply. It is incorrect to assume that your water contains the median or any specific concentration found in these samples. Detection does not imply a violation of safety standards or an unsafe condition. Also, uranium presence at these levels does not automatically create aesthetic or operational water issues. To make informed decisions about treatment, you must have your own water tested for uranium and radium levels and consider your household’s water use in determining treatment needs. The Pentair Uranium & Radium System can be a viable treatment option once you understand your water characteristics.

Source: USGS groundwater sampling. Sampled 2012-06-08. 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 Uranium in the 230SDMR aquifer (Lee County): 9 results from 9 wells, median 0.518 ug/L, range 0.014-2.19 ug/L; none above any federal threshold
