1. How Many Samples and Wells Are Behind the Manganese Results in This Area?

The manganese data for aquifer 112DFSF in FIPS 170, Connecticut, is based on three results from two separate wells. These wells were sampled over a period from September 30, 2011, to September 6, 2017. The wells were relatively shallow, between 19 and 24 feet deep. Because this dataset is small, it provides only a limited picture of manganese presence in the aquifer and should be seen as indicative rather than definitive for any single household.

2. What Do 'Detected,' 'Median,' and 'Range' Mean in These Manganese Measurements?

In this record, manganese was detected in all three samples, meaning the measuring instruments recorded its presence. The median concentration was 0.8 micrograms per liter (ug/L), which represents the middle value of the measurements. The range spanned from 0.6 to 180.0 ug/L, showing some variability between wells and times. Importantly, none of these measured manganese values exceeded any federal manganese thresholds, indicating no official exceedances in this sampling.

3. How Do Seasonal or Multi-Year Variations Appear in the Manganese Sampling Record?

The manganese sampling occurred at different times over nearly six years, allowing observation of longer-term trends rather than seasonal fluctuations. Variation within this period is evident in the wide range of manganese levels—from low to much higher results—suggesting that manganese concentrations can change over time or with conditions specific to each well. However, this does not specify seasonal patterns precisely, and individual well testing is needed to understand current household water conditions.

4. What Additional Questions Would a Commercial or Industrial Operator Consider That a Household Does Not?

While this page focuses on household concerns, commercial and industrial water users often inquire about manganese's impact on equipment efficiency, process contamination, and regulatory compliance for large-scale water use. They would need to analyze detailed manganese treatment requirements, monitor higher volumes, and consider water system integration factors. Households generally focus on aesthetic aspects like staining and taste, and the effects on plumbing fixtures and appliances rather than operational process impacts.

5. What Changes for a Large Household, a Second Home, or a Seasonal Property?

Larger households or properties used seasonally may experience different manganese challenges due to varying water usage patterns and storage. For example, stagnant water in seasonal homes can result in manganese settling or staining issues that differ from daily-use homes. Larger water volumes might require scaling filter capacity accordingly. The Pentair Black Manganese Stains Filter ships ready to configure and is designed to address manganese deposits, helping manage these effects across household sizes and usage patterns.

In summary, the manganese measurements for the aquifer 112DFSF area within FIPS 170, CT, are based on a small set of samples from two shallow wells taken over several years. Measurements show manganese consistently detected but within federal manganese thresholds. Understanding your own household’s manganese level requires specific water testing. The documented Pentair system offers a direct-purchase option to address manganese staining concerns effectively.

Source: USGS groundwater sampling. Sampled 2017-09-06. 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 Manganese in the 112DFSF aquifer (FIPS 170): 3 results from 2 wells, median 0.8 ug/L, range 0.6-180.0 ug/L; none above any federal threshold
