Reading Certified Laboratory Tests for Water Hardness

Test Reports Express Hardness in mg/L

Laboratory analyses measure hardness primarily as calcium and magnesium concentrations, reported in milligrams per liter (mg/L). For wells sampled in Washoe County’s N100BSNRGB aquifer, hardness values ranged from 18.4 to 210.0 mg/L, with a median near 92 mg/L.

Understanding the Range and Its Effect

The wide range indicates variability in mineral content between different wells. This mineral content contributes to spots on dishes by leaving mineral residue as water evaporates during drying.

Tests Do Not Confirm Your Water’s Hardness

Because regional sampling covers multiple wells, these figures reflect the area’s typical groundwater but do not indicate the specific hardness in your household water. Testing your own water through a certified laboratory is necessary for precise values.

Routine Care for the Pentair Spotty Dishes & Glassware System

Replacing Filter Cartridges at Recommended Intervals

The system ships ready to configure and requires cartridge changes on a schedule suggested by usage and manufacturer guidelines to maintain treatment effectiveness.

Flushing Components to Prevent Build-Up

Periodic flushing of the system components helps avoid scale accumulation that can reduce performance and contribute to spotting.

Monitoring Water Flow and Appearance

Regularly observing water clarity and flow rates provides early signs of necessary service actions to keep the system functioning optimally.

Mechanisms of Mineral Removal and Neutralization

Targeting Calcium and Magnesium Ions

The Pentair system reduces mineral content by exchanging calcium and magnesium ions with sodium or potassium ions, or by other filtration methods, to limit residue formation on dishes.

Preventing Spot Formation During Drying

By minimizing dissolved minerals, treated water evaporates with less mineral deposit, leading to fewer spots and clearer dishes.

Maintaining Consistent Water Quality for Dishwashers

The system helps sustain water quality levels consistent with improved rinse results, especially in households where existing equipment is insufficient.

Information to Gather Before Seeking Treatment Advice

Record Your Water Test Results with Dates

Including certified laboratory reports for your household water’s hardness will clarify treatment needs and system sizing discussions.

Note Existing Equipment and Its Performance

Detailing the capacity and limitations of your current water treatment helps identify gaps the Pentair system can address.

Document Water Usage Patterns and Dishwashing Habits

This contextual information supports assessing if treatment adjustments are warranted based on household demand.

Distinguishing Aesthetic Standards from Health-Based Guidelines

Secondary Standards Address Appearance and Taste Only

Aesthetic secondary standards, which cover hardness expressed as calcium and magnesium levels, are intended to guide acceptable water quality regarding taste, staining, and spotting effects, not health risks.

No Federal Health Violations Detected in Area Samples

Data from the Washoe County aquifer sampling show hardness results well within all federal thresholds, indicating no health-based violations.

Spotting Is an Aesthetic Concern, Not a Safety Issue

While mineral residue can be annoying on dishes, it does not indicate unsafe water; addressing it improves household convenience and satisfaction.

Spot-free dish challenges often stem from mineral content typical of Washoe County groundwater. Understanding your household’s water hardness through testing and routine care of treatment technology like the Pentair Spotty Dishes & Glassware System helps manage these effects effectively. This checklist guides you in gathering facts and taking steps toward clearer, spot-free dishes.

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 Hardness, Ca, Mg in the N100BSNRGB aquifer (Washoe County): 19 results from 15 wells, median 92.3 mg/L, range 18.4-210.0 mg/L; none above any federal threshold
