Step 1: The Role of Plumbing Material and Age, Independent of Source Water

When addressing acidic water issues, it’s important to distinguish between water chemistry originating from the source and changes caused by your home’s plumbing system. Materials such as copper, galvanized steel, or older pipes can interact with water differently, sometimes leading to localized acidity or corrosion not reflected in water source testing. Plumbing age and material type can influence water pH after it leaves the well or municipal source, so even if source water pH is neutral or slightly alkaline, household plumbing might contribute to perceived acidity.

Step 2: What a Certified Laboratory Test Reports for pH and How to Read It

A certified laboratory report for pH will list the water’s acidity or alkalinity as a numerical value measured in standard units. For water in Chatham County’s aquifer 120FLRDL, US Geological Survey data from wells 1056 to 1120 feet deep show a median pH of 8.0, with a range recorded between 7.7 and 8.2 across 12 samples taken between December 2011 and November 2013. These values are well within EPA’s secondary standard range of 6.5 to 8.5. It’s crucial to understand that a pH below 7 is acidic, exactly 7 is neutral, and above 7 is alkaline. Since none of the sampled results fell below 6.5, the aquifer water itself is not naturally acidic or outside aesthetic guidelines based on this regional data.

Step 3: How the Fleck System Treats Acidic or Low-pH Water

If your home water tests indicate a pH lower than desirable—whether due to source water conditions or plumbing interaction—the Fleck Acidic / Low-pH Water Filter system offers a practical solution. This system is designed to raise and stabilize pH levels, improving water quality and reducing potential corrosivity. It operates by neutralizing acidity before water reaches household fixtures, helping protect plumbing and improve water taste without complex procedures. The Fleck system ships ready to configure and can be integrated based on your home’s water demand and specific pH test results.

Step 4: Differences Between Public Water System Records and Private Well Testing

Public water system records for Chatham County reflect large-scale sampling from aquifer 120FLRDL and do not represent individual household water conditions. These regional tests provide a baseline but cannot substitute for testing your own well or tap water. Private wells may have different pH values influenced by local geology, well depth, and plumbing materials. Therefore, homeowners concerned about acidic water should obtain a certified laboratory analysis of their household water to capture precise pH and other relevant parameters.

Step 5: How pH Levels Enter Groundwater in Chatham County’s Aquifer

Water pH in Chatham County’s aquifer is influenced by natural interactions between groundwater and surrounding geology. The sampled wells at depths over 1000 feet indicate that the aquifer water maintains a slightly alkaline to neutral pH, reflecting underlying rock buffer capacity and minimal acidifying inputs. Factors such as soil composition, organic material decay, and local hydrology govern pH variations. Since none of the samples recorded acidic conditions, natural groundwater in this area typically does not contribute to acidic water problems in households directly from the source.

Step 6: Seasonal and Multi-Year Variation in pH Levels Based on Sampling Dates

The USGS sampling from December 2011 through November 2013 reveals minimal variation in pH, ranging from 7.7 to 8.2 with a stable median around 8.0. This data indicates that pH in the aquifer remains consistent across seasons and over multiple years within this timeframe. Homeowners noticing shifts in water acidity likely face influences other than aquifer chemistry, such as plumbing changes or contamination not captured in regional data. Continuous monitoring through certified lab testing is recommended for identifying any short-term fluctuations in your own water.

By following these steps and understanding government water-quality data, you can identify if acidic water is a concern for your household in Chatham County. The Fleck Acidic / Low-pH Water Filter system provides a documented method to counteract low-pH water based on your home's demand and test results, offering an effective approach to maintain water quality and protect plumbing.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2013-11-22. 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 120FLRDL aquifer (Chatham County): 12 results from 2 wells, median 8.0 standard units, range 7.7-8.2 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 12 sampled results fell below 6.5
