If your tap water tastes metallic or has a slightly sour note, you might be noticing signs of acidic water. In Mercer County, NJ, groundwater pH levels have been sampled extensively, offering a helpful overview of what residents can expect. Although this data can guide you, only a test of your own water can confirm its precise condition.
Steps to Rule Out Water Quality Issues
Check Water Appearance and Taste
Look for corrosion stains, bluish-green tints, or metallic flavors, which sometimes accompany acidic water.
Review Plumbing System Age and Material
Older pipes or certain metals can react more with acidic water, exacerbating potential effects.
Collect a Water Sample for Laboratory pH Testing
A certified laboratory test determines the exact pH of your household water, providing the data needed to assess acidity.
How Depth of Water Source Affects Expected pH
Groundwater Wells Between 35 and 174 Feet Deep
The U.S. Geological Survey sampled wells at these depths in Mercer County’s aquifer 231LCKG, reflecting typical local groundwater conditions.
Shallow versus Deep Wells Can Vary in pH
While regional sampling shows pH values ranging from 6.6 to 12.5, deeper wells may trend differently in acidity and alkalinity compared to shallow ones.
Interpreting the Regional Median and Range of pH
Median pH of 7.45 Indicates Near-Neutral Water
This median value from 184 samples suggests most groundwater in Mercer County is neither notably acidic nor alkaline.
Range from 6.6 to 12.5 Reflects Natural Variation
The lowest pH detected was 6.6, slightly above the EPA secondary standard lower limit of 6.5, meaning no sampled water fell into the acidic category by that measure.
Pre-Treatment Notes to Record
Write Down Your Water’s Source and Well Depth
Knowing whether your water comes from a shallow or deep well helps interpret sample data and treatment needs.
Note Any Water Taste, Smell or Staining
Details on taste or visible effects support assessing whether acidity may affect your household.
Have Recent Lab Results Available
Documentation of your own water’s pH and other parameters is essential for proper evaluation.

Seasonal and Multi-Year Variations in Mercer County Groundwater pH
Regionally Sampled Data Spanning 2010 to Mid-2025
The broad timespan of samples captures effects of changing seasons and hydrogeologic shifts on groundwater pH.
Consistent Median and Range Over Time
The evidence shows stable pH levels without significant long-term shifts toward acidity, indicating stable water chemistry for Mercer County in general.
These findings reflect the well depths and aquifer 231LCKG area sampled, not any individual water source. For personal water conditions, a specific water test is necessary. See the U.S. Geological Survey's detailed groundwater records for Mercer County at their official site.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-07-24. 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 231LCKG aquifer (Mercer County): 184 results from 29 wells, median 7.45 standard units, range 6.6-12.5 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 184 sampled results fell below 6.5
