Are you noticing a metallic taste in your household water? In Cumberland County, NJ, regional water studies provide clues but not certainties about the severity of such issues at individual taps. This page helps you understand what local manganese sampling means and what steps to consider next.
If you want to compare Cumberland County’s manganese record with neighboring counties without overreading it
Sampling from aquifer 121CKKD in Cumberland County shows manganese was detected in almost all tests, with a median of about 27 micrograms per liter and a range from less than 1 up to over 3,000 micrograms per liter. Neighboring counties may have different ranges or median values, but these figures describe broad regional trends and do not predict a specific home's water quality. Variations in geology, well depth, and sampling methods mean that comparing counties can offer context but should not directly determine your water condition or solutions.
If you want to understand how many samples and wells stand behind these manganese figures and what a small sample means
The data for Cumberland County comes from 102 results collected at 49 wells between 2010 and 2024, with well depths ranging from 11 to 181 feet. This volume of sampling provides a meaningful regional overview but is not a substitute for testing your own water. A smaller or more limited sample set might not capture the full variation within an area, so relying solely on these numbers for your household’s water could be misleading.
If you want to know how public water system records differ from private well testing in what they establish
Government records show that sampled wells in this area do not exceed any federal manganese limits, indicating no regulatory concern at the regional level. However, these samples are not from municipal distribution systems but from groundwater wells. A private well’s actual manganese level may vary significantly and can only be confirmed by testing that specific well. Public system records typically exclude private wells and do not detail taste or aesthetic qualities for individual households.
If you want to understand how manganese enters groundwater or distribution systems in Cumberland County
Manganese is a naturally occurring mineral in the area's aquifer, influenced by local geology and well depth. It can dissolve into groundwater as water interacts with soil and rock formations. When manganese interacts with household plumbing or water exposure conditions, it can sometimes contribute to a metallic taste. In municipal water systems, treatment may reduce manganese but will depend on treatment goals and source water conditions.
If you want to know what 'detected', 'median' and 'range' mean in the sampling record on this page
- Detected: Water samples where manganese was measurable, not implying any violation or unsafe condition.
- Median: The middle value of manganese measurements, showing a central tendency but not indicating a household's exact reading.
- Range: The spread from the smallest to the largest manganese value found in the samples, illustrating natural variation in the aquifer.
If you are a commercial or industrial operator with additional questions about manganese in water
Aside from taste concerns relevant to households, commercial and industrial users often evaluate manganese's impact on processes, equipment wear, and product quality. They typically require detailed water analysis at the facility point and may consider manganese’s chemical interactions in their systems. These factors go beyond the typical household scope but emphasize the value of knowing your specific water profile through testing.
In summary, the manganese data for Cumberland County aquifer 121CKKD covers a substantial set of wells sampled over many years and indicates no federal manganese threshold exceedances. For your household’s metallic taste issue, testing your own water is the only way to determine the manganese concentration and its role. To address taste concerns tied to manganese, the Autotrol Metallic-Tasting Water Filter ships ready to configure and can be a suitable treatment option.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-08-13. 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 121CKKD aquifer (Cumberland County): 102 results from 49 wells, median 26.9 ug/L, range 0.42-3230.0 ug/L; none above any federal threshold
