1. Interpreting 'Detected,' 'Median,' and 'Range' in New Castle County Radon Sampling

When you see the term 'detected' in government water data for New Castle County’s aquifer 125RCCS, it means that radon-222 was measured at or above the instrument’s detection limit in samples from 23 separate wells. In this area, all wells sampled between June 10 and August 20, 2015 showed radon-222 detection. The median concentration found was 223.0 pCi/L, and concentrations ranged from 85.0 to 1870.0 pCi/L. These values represent what was found in those wells, not your household water specifically. Detection does not indicate a violation or unsafe condition by itself.

2. Matching Treatment Capacity to Household Water Use

Considering radon treatment means ensuring the system’s capacity meets your household’s daily water demand. Radon in water systems like the Pentair Radon in Water Filter are designed to handle typical household flow rates and radon concentrations similar to those documented in this area. To judge if this treatment fits your use, compare your household’s peak water consumption patterns with the system’s rated capacity documented by the manufacturer. This ensures effective radon reduction without flow disruption.

3. Understanding the Number of Samples and Wells Behind the Data

The radon-222 levels for New Castle County’s aquifer 125RCCS come from 23 wells, all sampled once in summer 2015. The wells ranged between 66 and 300 feet in depth. Though 23 is a moderate sample size, it provides a snapshot of radon occurrence in groundwater for this area. Individual wells may vary outside this range, so the data informs about the aquifer generally but cannot determine your own water’s radon level.

4. Seasonal and Multi-Year Variation in Radon Levels

The samples were collected over a roughly two-month summer period in 2015, offering a time-specific view. Radon concentrations in groundwater can vary seasonally and over years due to natural changes in water chemistry and flow. The data set does not show longer-term fluctuations or differences outside this sampling window, so monitoring or testing your own water at different times may be necessary to understand your situation fully.

5. Symptoms That Do and Do Not Indicate Radon in Household Water

Radon is a radioactive gas that is odorless, colorless, and tasteless. Unlike some water contaminants, it does not cause visible changes or odors in your water. Therefore, common household symptoms like discoloration, cloudiness, or unusual taste do not point to radon. Testing is the only way to confirm radon levels in your water.

6. Aesthetic Secondary Standards Versus Health-Based Limits for Radon

Radon levels measured fall below any federal health-based thresholds. It's important to understand that aesthetic secondary standards relate to taste and staining properties and do not apply to radon. Radon’s guidelines are health-based and focus on radiation safety. The government data here shows radon present but within ranges considered by federal criteria as not exceeding health-based limits for groundwater.

In summary, the New Castle County sampling record from the U.S. Geological Survey reflects radon found in 23 wells of aquifer 125RCCS, ranging from 85.0 to 1870.0 pCi/L, with a median of 223.0 pCi/L, all below federal thresholds. These figures provide a useful regional context but do not describe your household well’s water quality. Testing your water directly is essential to determine if radon treatment is necessary. If treatment is chosen, the Pentair Radon in Water Filter ships ready to configure and is designed to manage radon removal effectively at typical household water demands.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2015-08-20. 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 Radon-222 in the 125RCCS aquifer (New Castle County): 23 results from 23 wells, median 223.0 pCi/L, range 85.0-1870.0 pCi/L; none above any federal threshold
