Recognizing Acidic Water Versus Commonly Confused Water Issues
If you notice a metallic taste or corrosion around your faucets, you might suspect acidic water. Acidic water is characterized by a pH below neutral (7.0), indicating more hydrogen ions present. This differs from water issues like hardness or iron staining, which result from mineral content rather than pH levels. In Bernalillo County, the term acidic water focuses specifically on the water’s pH and its potential effects on plumbing and water quality.
Influence of Well Depth and Source Type on pH Expectations
Groundwater pH can vary depending on how deep wells are drilled and the type of aquifer tapped. Bernalillo County wells sampled ranged from 90 to 306 feet deep within aquifer N9999OTHER. Deeper wells often access water that has interacted longer with geological formations, potentially stabilizing pH near neutral levels. The U.S. Geological Survey data for this area shows a median pH of 7.5 standard units, with values ranging between 6.7 and 7.9. None of these samples fell below the secondary EPA aesthetic standard of 6.5, indicating acidic water occurrences are mild when they occur.
Questions Unique to Commercial or Industrial Water Use
While residential users focus on taste and plumbing effects, commercial or industrial water users may need additional assessments such as scaling potential, compatibility with equipment materials, or impact on manufacturing processes. These operations often require precise pH management and tailored water treatment plans that consider volume and water chemistry. Households generally address acidic water to protect pipes and improve water quality for daily use.
Origins of pH Variation in Bernalillo County Groundwater
The pH level in groundwater is affected by natural processes such as the mineral composition of the soil and rock in contact with water, carbon dioxide levels, and microbial activity. In Bernalillo County’s aquifer N9999OTHER, the balanced pH range observed by federal sampling suggests that natural buffering capacity helps maintain near-neutral pH conditions. However, localized variations or man-made influences can cause water to become more acidic, which may accelerate metal leaching from plumbing materials and cause aesthetic issues.
Comparing Bernalillo County pH Data with Neighboring Areas
When looking at water pH records from Bernalillo County alongside those from nearby counties, it is important to consider geological differences and sampling scopes. Differences in aquifers, well depths, and land use can shift pH ranges. Bernalillo County’s median pH of 7.5 and range from 6.7 to 7.9 represents a relatively stable and acceptable range for household water. Avoid assuming these values apply universally to individual wells without direct testing.
In summary, the U.S. Geological Survey’s monitoring of wells 90 to 306 feet deep in Bernalillo County’s aquifer N9999OTHER shows pH values consistently above 6.5. This indicates low risk of strongly acidic water within the sampled area but does not replace testing your household water to confirm local conditions. For homes experiencing low-pH water, the C-Series Acidic / Low-pH Water Filter ships ready to configure and is designed to address acidic water by balancing pH levels to protect plumbing and improve water quality.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-09-03. 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 pH in the N9999OTHER aquifer (Bernalillo County): 9 results from 4 wells, median 7.5 standard units, range 6.7-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 9 sampled results fell below 6.5
