Government groundwater sampling in Sedgwick County's 112PLSC aquifer recorded chloride in 335 of 337 samples from 89 wells at depths from 25 to 260 feet, with a median chloride concentration of 67.0 mg/L and a range of 6.5 to 2800.0 mg/L between May 2010 and September 2016. This chloride presence indicates conditions that can contribute to corrosive water behavior affecting household plumbing but does not indicate unsafe water quality.
Assessing Treatment Capacity Relative to Daily Household Water Demand
Calculate your household's average daily water use to ensure sufficient treatment capability
Compare treatment system capacity against peak water consumption periods
Verify that treatment technology can handle fluctuations typical for residential water draws
Recognizing Seasonal and Multi-Year Variability in Water Quality
Note that sampling data spans over six years, showing variable chloride levels across time
Understand that water quality may fluctuate seasonally due to aquifer recharge and usage patterns
Use multiple test results rather than single measurements to understand typical conditions
Why Secondary Standards for Chloride Are Aesthetic, Not Health-Based
Secondary standards set at 250 mg/L chloride focus on taste, staining, and pipe corrosion potential
Exceeding these aesthetic thresholds does not indicate a health violation or unsafe water
Corrosive effects may manifest through discoloration or metal leaching but do not imply toxicity
Fixtures and Appliances Most Vulnerable to Corrosive Water Effects
Older metal pipes and solder joints may show early signs of corrosion damage
Water heaters and dishwashers can accumulate scale or rust from corrosive water action
Faucet aerators and plumbing vents may clog more frequently due to sediment buildup
Distinctions Between Public-System Records and Private Well Testing
Public systems often provide records covering broad geographic areas and multiple sources
Private well testing is necessary to determine specific water quality at an individual residence
Regional data indicate potential concerns but cannot define conditions of a single household supply
Essential Information to Gather Before Seeking Treatment Advice
Obtain recent, comprehensive water quality analysis from your own water source
Document water use volumes and any observed plumbing issues or discoloration
Note your plumbing materials and equipment age for compatibility with treatments
All data referenced come from public groundwater sampling in Sedgwick County’s 112PLSC aquifer collected from 2010 through 2016, as available at the U.S. Geological Survey site. Proper evaluation of your household water quality requires direct testing of your source, and treatment options such as the Autotrol Corrosive Water Damaging Pipes Filter ship ready to configure to address corrosive water conditions documented in the area.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-15. 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 112PLSC aquifer (Sedgwick County): 337 results from 89 wells, median 67.0 mg/L, range 6.5-2800.0 mg/L; 73 above an AESTHETIC secondary standard only (secondary standard 250.0 mg/L (aesthetic)) - not a health finding
