1. Reading the Area Sampling Median and Range as a Homeowner Would
The U.S. Geological Survey sampled 16 wells in Bernalillo County's aquifer 112SNTFU, tracing manganese levels—a common cause of metallic taste in water. The median concentration measured was 24.85 micrograms per liter (ug/L), with results ranging from as low as 0.29 up to 926.0 ug/L. This range shows that manganese presence varies considerably across wells in this area. Importantly, these figures describe overall local groundwater conditions, not any specific household's water.
2. Understanding Differences Between Public-System Records and Private Well Tests
Public records like this represent aggregate data from multiple wells sampled over years, offering a regional perspective. Unlike direct testing of your home's water supply—which reveals specific manganese levels and clarifies the source of metallic taste—the area data cannot establish your well's condition. Testing your water independently is essential to know the precise concentration responsible for any taste issues.
3. What the Sampling Range Means in Relation to Federal Standards—and What It Does Not Mean
None of the manganese results in the sampled wells exceeded federal health-based thresholds. This means the manganese levels found do not officially signify unsafe drinking water by federal criteria. However, manganese is subject to aesthetic secondary standards that address taste, staining, and corrosion potential. Exceeding these may cause metallic taste and other nuisances without indicating a health hazard.
4. Clarifying Terms: 'Detected,' 'Median,' and 'Range' in This Sampling Record
'Detected' means the measuring instruments found manganese at the stated concentration; it is not a violation or health issue by itself. 'Median' indicates the middle value of manganese concentrations when ordered, helping summarize the data. 'Range' shows the minimum and maximum levels recorded across samples. Knowing these terms helps interpret the sampling results accurately without assuming your household water matches these exactly.
5. Fixtures, Appliances, and Processes Most Impacted by Metallic Taste
A metallic taste commonly appears first in drinking water taps and kitchen appliances like coffee makers and ice machines sensitive to manganese. Showers or other uses may not reveal taste issues as quickly. The presence of manganese can also cause minor discoloration, affecting utensils or glassware. Identifying the sources in your home where metallic taste is noticed helps target remediation effectively.
Closing Note: Area manganese data from Bernalillo County's aquifer provide valuable context but do not specify your home's water quality. To address metallic taste fully, testing your own water is necessary. Once manganese presence and levels are confirmed, solutions such as the Autotrol Metallic-Tasting Water Filter ship ready to configure and use, helping reduce metallic taste impacts reliably.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-10-17. 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 112SNTFU aquifer (Bernalillo County): 381 results from 16 wells, median 24.85 ug/L, range 0.29-926.0 ug/L; none above any federal threshold
