When a water quality lab report lists pH, it reflects the acidity or alkalinity of the water on a scale from 0 to 14, where 7 is neutral. The U.S. Geological Survey sampled groundwater from 39 wells in the Curry County aquifer between May 2021 and May 2023. The median pH was 7.7, with values ranging from 7.3 to 8.5, all above the threshold that the EPA sets as its secondary standard for pH (6.5 to 8.5). This range indicates that, regionally, groundwater is generally neutral to slightly basic rather than acidic.
Myth: All plumbing fixtures suffer immediately from acidic water
The reality is that acidic water—defined conventionally as pH below 6.5—may not be present in Curry County aquifer samples studied, and even mild acidity causes damage primarily to metal fixtures and appliances sensitive to pH over extended periods. Fixtures such as faucets, pipes, and water heaters are typically the first to show effects like corrosion or dripping due to acidity if it exists in your household water at sufficiently low pH levels. Since regional sampling showed no results below the EPA’s aesthetic lower bound, widespread immediate corrosion risk in Curry County homes is not supported by this data alone.
Myth: Untreated acidic water will cause catastrophic home damage
Leaving acidic water untreated can, under certain conditions, contribute to gradual wear on plumbing and appliances over many years. However, because the Curry County aquifer’s recorded pH values generally fall within the EPA’s secondary standard, the potential for such long-term effects from acidity alone is low in this region. Monitoring your own water’s pH remains essential, as localized conditions can differ from area averages.
Myth: Public water system records directly reflect private well water quality
Public water system records often cover treated water at distribution points and may differ significantly from the chemistry of untreated groundwater drawn from private wells. The Curry County aquifer data from the U.S. Geological Survey represents untreated groundwater samples at depths between 225 and 430 feet. Your private well water pH can vary based on depth, location, and local geology. Testing your specific water source is necessary to understand your household’s water acidity accurately.
Myth: Acidic water is removed by any basic filtration system
The Autotrol Acidic / Low-pH Water Filter is designed specifically to address low-pH water by neutralizing acidity through a controlled filtration process that raises the pH toward a more neutral level. This system ships ready to configure with your plumbing and water flow parameters. It is tailored to counteract acidic water’s effects and helps protect household plumbing and appliances where water tests indicate low pH values.
Myth: The EPA’s pH range sets a strict safety limit that all wells in the area must meet
The EPA secondary standard for pH (6.5 to 8.5) concerns aesthetics and potential corrosivity, not health safety. The Curry County aquifer groundwater samples all registered within or above this range, with no readings below 6.5. This means acidic water, defined as pH below 6.5, was not detected in the USGS area sampling. Individual well testing is still advisable to confirm your own water’s pH and decide if treatment is necessary.
Myth: Curry County’s pH record can be reliably compared directly to neighboring counties
While adjacent counties may have similar geological formations, hydrogeological conditions, and pH ranges, each aquifer system is unique. Differences in soil composition, depth of wells sampled, and water-table dynamics can create variability. Comparing Curry County’s pH data with neighboring counties requires attention to sampling depth, dates, and measurement methods to avoid misinterpreting subtle differences as a direct indicator of your well’s water quality.
Understanding your water’s acidity level demands testing your specific source. If you determine your water is acidic or low-pH, the Autotrol Acidic / Low-pH Water Filter provides a direct solution to neutralize acidity, preserving household plumbing and improving water quality. This system ships ready to configure based on your household’s measured water demand and acidity level.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2023-05-24. 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 aquifer (Curry County): 46 results from 39 wells, median 7.7 standard units, range 7.3-8.5 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 46 sampled results fell below 6.5
