Understanding 'Detected,' 'Median,' and 'Range' in Local Water Sampling

The U.S. Geological Survey collected six pH samples from wells in Cumberland County’s aquifer 112SRFD between 2011 and 2019. 'Detected' means that pH values were measurable in all samples, with none below detection limits. The median pH was 6.6 standard units, indicating the midpoint of the dataset. The recorded pH values ranged from 6.3 to 7.2 standard units. These figures represent water from specific wells at a depth of approximately 54 feet and characterize general conditions in this aquifer but do not define any individual household’s water quality.

Stepwise Approach: From Basic Checks to Laboratory Testing

First, households noticing acidic water effects should verify appliance and plumbing condition, as equipment failure might mimic water issues. Next, simple pH test strips or handheld meters can provide initial water pH indications at the tap. For an accurate assessment, water samples should be sent to an accredited laboratory for comprehensive pH measurements and related characteristics. This hierarchy helps distinguish equipment faults from true water chemistry concerns before pursuing treatment options.

Differences Between Public Water Records and Private Well Testing

Public water system records reflect large-scale monitoring and regulatory reporting, providing data averaged over wide service areas and timeframes. In contrast, private well testing reveals specific water chemistry at a single point in time and location, which can vary significantly from public data. The USGS sampling for Cumberland County’s aquifer offers a regional snapshot, useful for understanding background conditions but not a substitute for individual testing where private wells are concerned.

Seasonal and Multi-Year Variation in pH Levels

The six samples span eight years, from August 2011 to September 2019. The pH variation between 6.3 and 7.2 standard units during this period suggests some natural fluctuation in water acidity but generally remains close to the EPA’s secondary aesthetic range of 6.5 to 8.5. This variation might relate to environmental factors such as rainfall, groundwater flow changes, and aquifer recharge patterns. Understanding these trends can help homeowners anticipate when water conditions might shift.

Distinguishing Secondary Aesthetic Standards from Health Limits

The pH thresholds from EPA’s secondary standards address water’s taste, staining potential, and pipe corrosion risk, not health effects. A reading slightly below 6.5, as seen in one of the samples, flags increased acidity, which can accelerate metal leaching from plumbing and damage household fixtures over time. It is important to recognize that a pH below this range is not a safety violation but signals a condition that may require treatment for property preservation and water quality preferences.

Households experiencing acidic water effects, especially after existing equipment has failed, may benefit from using a Pentair Acidic / Low-pH Water Filter. This system ships ready to configure and helps neutralize acidity, protecting pipes and improving water characteristics associated with low pH.

In summary, this briefing reviewed regional pH data and explained how to interpret sampling results, distinguish water quality from equipment issues, and understand regulatory standards. Testing your own water remains essential to confirm conditions and guide the choice of treatment like the Pentair Acidic / Low-pH Water Filter.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-09-10. 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 112SRFD aquifer (Cumberland County): 6 results from 1 wells, median 6.6 standard units, range 6.3-7.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 1 of 6 sampled results fell below 6.5
