Government Sampling Data on Orangeburg County Aquifer 111SANDD

The U.S. Geological Survey has monitored groundwater in Orangeburg County's aquifer 111SANDD, analyzing chloride levels from seven separate wells between 2011 and 2018. Chloride was detected consistently, with concentrations ranging from 10.6 to 23.5 mg/L and a median value of 18.85 mg/L. These measurements come from wells 12 to 24 feet deep and none surpassed any established federal guidelines for water quality.

Considerations for Large, Seasonal, or Secondary Residences

Households with greater water use, such as larger families or properties occupied only part of the year, may experience different corrosion dynamics. Higher water volume can influence how quickly corrosive effects develop. Seasonal homes might see variations in water stagnation or temperature that impact corrosivity. These factors should be considered when evaluating treatment needs and frequency of water quality testing.

Steps to Identify the Corrosion Risk in Your Household Water

Start with visual inspections for signs of corrosion such as discoloration or leaks around pipes and fixtures. Simple water tests for pH and total dissolved solids can help indicate corrosivity. For precise understanding, laboratory testing can measure factors specifically linked to corrosion potential, informing the selection and configuration of treatment equipment.

Interpreting "Detected," "Median," and "Range" in the Sampling Record

Each term describes a different aspect of the data collected. "Detected" means instruments found measurable chloride in all sampled wells, not that levels are harmful. "Median" indicates the central value in the dataset, representing a typical measurement. "Range" shows the span between the lowest and highest detected levels, offering insight on variability within the area. None of these statistics pinpoint your individual water quality but help define regional patterns.

Differentiating Corrosive Water from Commonly Confused Issues

Corrosive water primarily risks pipe degradation via chemical action, often linked to low pH or certain dissolved constituents. This contrasts with hardness problems caused by calcium or magnesium, which lead to scaling instead, and with microbial contamination, which presents health risks but does not corrode pipes. Proper diagnosis ensures selecting the correct approach to protect household plumbing.

Example: Understanding the Chloride Data for Your Home

With chloride levels measured between 10.6 and 23.5 mg/L and a median of 18.85 mg/L in area wells, residents can gauge where their water might fall within this range once tested. Chloride influences water taste and corrosion potential; staying within these documented values suggests typical regional conditions but does not exclude localized differences. Your own water test will confirm how your household compares.

Fixtures, Appliances, and Processes Most Affected by Corrosive Water

Corrosion tends to impact metal pipes and fixtures first, especially those made of copper or galvanized steel. Appliances relying on water contact such as water heaters, dishwashers, and coffee makers may suffer damage over time. Corrosive water can also affect household water quality by releasing metals and increasing maintenance needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2018-11-05. 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.
