This week, your household faces an important decision about choosing the right class of treatment for corrosive water detected in your area’s water source.
Consequences of Leaving Corrosive Water Untreated Over Years
Progressive Pipe Deterioration
Corrosive water can gradually damage plumbing by eating away metal pipes and fixtures, potentially leading to leaks and costly repairs over time.
Increased Water System Maintenance
Extended exposure to corrosive water may accelerate wear on household water appliances and promote buildup of minerals that impair function.
Interpreting Richland County Aquifer Chloride Levels Against Federal Thresholds
Chloride Detected in All Samples Within Safe Limits
U.S. Geological Survey data from 2011 to 2016 show chloride concentrations ranging from 1.29 to 23.3 mg/L in 26 wells of aquifer 211MDDF within Richland County.
All Measurements Below Federal Taste, Corrosion Control Thresholds
None of these readings exceed federal secondary standards related to taste and corrosivity, indicating that while chloride is present, it does not constitute a legal violation or confirmed safety risk.
Chloride Levels Alone Do Not Define Corrosivity
Chloride concentration contributes to corrosive potential but must be assessed alongside other factors such as pH and alkalinity, which are not provided in this data set.
Distinguishing Corrosive Water from Other Common Water Issues
Corrosion vs Mineral Hardness
Unlike hardness caused by calcium or magnesium, corrosive water primarily affects metal plumbing integrity rather than causing scale buildup or spotting.
Corrosion vs Discoloration or Sediment
Corrosive water typically does not cause visible sediment or cloudiness; these may indicate different water quality concerns.
Seasonal and Multi-Year Variation Observed in Sampling Record
Sampling Over Five Years Captures Wide Range
The samples collected between August 2011 and September 2016 show chloride ranging from 1.29 mg/L to 23.3 mg/L, reflecting natural fluctuations in the aquifer over time.
Well Depths Varied, Showing Aquifer Diversity
Wells sampled ranged from 9 to 140 feet deep, demonstrating that corrosive potential may differ depending on local groundwater conditions.
Understanding a Certified Laboratory Test Result for Corrosive Water
Look for Chloride Concentration and Range
A certified lab report for your household water will indicate specific chloride levels that help assess corrosive tendencies compared to area benchmarks.
Additional Parameters Improve Diagnosis
Tests including pH, alkalinity, and total dissolved solids offer a more complete picture of corrosivity beyond chloride alone.
Use Results to Match Treatment to Severity
Knowing your precise water chemistry guides the selection of treatment technology appropriate for your household’s corrosive water challenges.
Deciding the right treatment requires understanding what government sampling shows about regional water quality and testing your own water for specifics. The Pentair Corrosive Water Damaging Pipes Filter ships ready to configure and addresses corrosivity in plumbing by reducing damaging constituents based on your water profile.
This checklist has laid out how to interpret area data, distinguish corrosive water from other issues, and evaluate testing to make an informed choice about treatment in Richland County’s aquifer 211MDDF.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-01. 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 Chloride in the 211MDDF aquifer (Richland County): 30 results from 26 wells, median 9.975 mg/L, range 1.29-23.3 mg/L; none above any federal threshold
