Interpreting a Laboratory Test Report for Chloride in Your Well Water
Median and Range Explained for Chloride in St. Lawrence County Aquifer 367BKMN
The U.S. Geological Survey sampled groundwater from 10 separate wells in St. Lawrence County’s aquifer 367BKMN between 2010 and 2020. Chloride was detected in all 11 samples, with a median concentration of 31.9 mg/L and a range spanning from 2.68 mg/L to 1160.0 mg/L. These figures reflect measurements gathered at well depths between 60 and 280 feet. This data is not a direct reading of your own water but a regional reference to help understand typical chloride presence.
Comparing St. Lawrence County’s Chloride Record Without Overreading
Recognizing Variation and Limits in Regional Data
Data reflects a small set of sampled wells, so concentrations can vary widely within the aquifer. Some samples exceeded the secondary aesthetic standard for chloride of 250 mg/L, a threshold related only to taste and staining—not health or safety. When sizing treatment systems, it’s important to recognize these regional values do not predict exact local conditions and must not be interpreted as unsafe or legally noncompliant.
Understanding Sample Size and Its Influence on Reliability
Number of Wells and Samples Behind Regional Chloride Levels
The 11 samples originated from 10 wells, indicating a limited but diverse snapshot of the aquifer’s chloride conditions. A small sample size means the reported median and range capture some variability but may not show all occurrences. Testing your own water is essential to determine the correct treatment sizing rather than relying solely on regional statistics.
Considering Plumbing Material and Age in Your Water Treatment Needs
How Household Pipes Affect Water Quality Separate from Source
Water chemistry at your tap can be influenced by your household’s pipes and fixtures, unrelated to the source water’s chloride levels. Older or certain pipe materials might alter taste or cause stains independent of well water composition. Effective total well water treatment addresses source water concerns and can accommodate these plumbing-related effects when configured correctly.
Distinguishing Total Well Water Treatment from Commonly Confused Issues
Clarifying What Chloride Data Does and Does Not Indicate
Total well water treatment often targets issues such as microbial contamination or iron presence, which differ from chloride-related aesthetic concerns. The regional chloride data serves to inform taste and staining potential, not to signal health risks or operational failures. Recognizing these distinctions helps focus treatment system sizing on the true needs present in your water.
Summary of Regional Chloride Record and Sizing Guidance
The U.S. Geological Survey’s record for St. Lawrence County aquifer 367BKMN shows chloride detected in all samples with a median of 31.9 mg/L and some results above an aesthetic threshold of 250 mg/L. This data covers wells between 60 and 280 feet deep but does not describe individual well conditions. To size total well water treatment accurately, testing your own water is important. The C-Series Total Well Chlorination System ships ready to configure, addressing broad source water and plumbing factors with a high grain capacity of 32,000.

On record: U.S. Geological Survey sampling of Chloride in the 367BKMN aquifer (St. Lawrence County): 11 results from 10 wells, median 31.9 mg/L, range 2.68-1160.0 mg/L; 2 above an AESTHETIC secondary standard only (secondary standard 250.0 mg/L (aesthetic)) - not a health finding
