The groundwater supplying homes in Doña Ana County primarily draws from aquifer 110ALVM. Water moves through this aquifer and is accessed by wells of varying depths, then directed to household taps. Understanding manganese presence within this local water source involves looking at regional sampling records and recognizing what they mean for everyday water use.
If you notice that manganese levels in your water vary seasonally or across several years
Government data sampled between May 2010 and May 2019 from 21 wells ranging 15 to 110 feet deep in this aquifer found manganese detected in all 53 results. Concentrations ranged widely, with a median value of 1610 micrograms per liter and an overall span from 0.62 to 3360 micrograms per liter. These fluctuations suggest that manganese concentrations in the aquifer can change with natural seasonal or multi-year factors such as rainfall, groundwater flow, and aquifer recharge patterns.
If manganese presence in water is left without treatment for several years
While no sample in this set exceeded federal manganese thresholds, manganese at elevated levels may gradually cause aesthetic effects like discoloration or staining on plumbing fixtures and laundry. Prolonged exposure without addressing manganese can result in noticeable deposits on surfaces that contact water, potentially affecting the appearance of sinks, tubs, and fabrics.
If you detect staining or discoloration primarily on certain household fixtures or appliances
Areas most often affected first are those with frequent water contact, such as bathroom sinks, toilets, and washing machines. This pattern occurs because manganese can settle and accumulate on surfaces where water evaporates or flows slowly. Appliances involved in water heating or washing may show early signs due to manganese interaction during use.
If you are considering what the government’s limited sample size means for your water
This set of manganese measurements covers 21 wells sampled 53 times over nearly a decade. While this provides a valuable regional overview, individual well concentrations can differ. The data’s breadth offers insight into area conditions but cannot substitute for testing your specific water source. A smaller sample size or single reading may not capture the full range of manganese variation in your household water.
If you want to compare manganese data in Doña Ana County with nearby counties
Comparisons can provide context but should be approached cautiously. Geological and hydrological differences between counties impact manganese levels. Trends in neighboring regions may not reflect your aquifer’s unique characteristics or your well’s depth. Area data are a reference point, not a definitive indicator for individual water conditions.
Overall, the presence of manganese in Doña Ana County’s aquifer 110ALVM, as documented by the U.S. Geological Survey, shows it is a naturally occurring constituent with concentration variations over time and location. This data does not confirm your home water’s manganese concentration or safety. Testing your well water is necessary to understand your household’s specific manganese levels and to decide if treatment is appropriate. For those seeking to address manganese-related stains or discoloration, the C-Series Black Manganese Stains Filter ships ready to configure as a proven solution designed to reduce manganese effects in residential water supplies.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-05-15. 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.
