Understanding Certified Laboratory Tests and Their Results
What a lab test reports for calcium and magnesium
A certified laboratory test measures the combined concentration of calcium and magnesium ions in a water sample, reported in milligrams per liter (mg/L). This measurement indicates the water's total hardness level, a key factor affecting soap lather, since these minerals react with soap molecules to reduce foam and cleaning efficiency.
Interpreting the lab report
The value reflects only the tested sample from a specific well or tap and does not represent the entire area. It helps identify how much soap interaction to expect but does not alone determine safety or compliance, as these minerals are naturally occurring and not regulated as contaminants in this context.
Seasonal and Multi-Year Variation in the San Juan County Aquifer
Data collection dates
The U.S. Geological Survey collected 11 sample results from 8 different wells in the San Juan County aquifer between September 2024 and September 2025. These cover multiple seasons and provide a snapshot of conditions over one year.
Range and median values
Hardness levels ranged from 449.0 to 1560.0 mg/L with a median of 1120.0 mg/L. These variations show natural fluctuations in mineral concentrations over time and location but do not indicate any health-based exceedances in the area.
Checklist to Rule Out Soap Lather Issues in Your Household
Step 1: Check soap type and usage
Some soaps are specifically formulated to lather better in hard water. Trying a different soap or adjusting usage can be the simplest first step.
Step 2: Examine water flow and fixture condition
Clogged or aged fixtures may alter water pressure and affect how soap lathers. Ensuring clean and functional fixtures is a basic household check.
Step 3: Obtain a certified water hardness test for your source
Since area data is indicative but not definitive for your well or tap, a certified lab test on your household water is necessary to know your specific hardness level and plan accordingly.
Evaluating Treatment Capacity According to Household Daily Water Demand
Estimate daily water use
Calculate the total gallons used daily for bathing, cleaning, and other activities where soap lather is important. This informs how much water will need treated at peak times.
Match treatment system capacity
Choose a system able to process the estimated volume without reducing water pressure or efficiency. Proper capacity ensures consistent soap lather improvement throughout daily routines.
Maintenance Rhythm for the Fleck Soap Won't Lather System
Regular upkeep
The Fleck System requires periodic replenishment or conditioning of its media to maintain performance. This maintenance interval depends on household water usage and hardness levels but typically follows a predictable schedule.
Monitoring system indicators
Watch for changes in water feel and soap lather quality as signs maintenance or media refresh may be needed. Keeping up with this extends the system's effectiveness for soap lather improvement.
Impact of Well Depth and Water Source on Expectations
Well depths in sampled area
The USGS samples were from wells ranging between 37 and 101 feet deep within the San Juan County aquifer. Depth can influence mineral concentration but is only one factor affecting hardness.
Variation by source
Different water sources such as surface water or deeper aquifers may have different mineral profiles. Knowing your source helps set realistic expectations for soap lather challenges and treatment needs.
The San Juan County aquifer data represents mineral levels measured in multiple wells over one year and provides a regional perspective but does not characterize individual household water. For precise results, testing your own water through a certified laboratory is essential. This government information is publicly accessible at the US Geological Survey monitoring location page for further reference.
