Gwinnett County's water commonly comes from the 320CRSL aquifer, where groundwater is accessed through wells generally between 280 and 600 feet deep. This water passes through home plumbing before reaching your dishwasher and taps, carrying natural minerals that can affect dishware appearance.
Household Signs Indicative and Non-Indicative of Spotting Issues
Visible spots or streaks after dishwashing are a common symptom related to mineral presence.
Cloudiness or films on glassware may stem from detergent residue or rinse agent levels, not necessarily from water minerals.
Presence of rust-colored stains typically points to iron content, a different concern unrelated to spotting from minerals in this area.
Dishes that rinse completely clear but develop spots only after drying point toward mineral deposits from local water sources.
Influence of Well Depth and Water Source on Water Characteristics
Wells in the 320CRSL aquifer range in depth from 280 to 600 feet, which influences the concentration of dissolved minerals reaching household taps.
Samples taken from these depths in Gwinnett County show calcium and magnesium levels contributing to water composition, but no results exceed federal standards.
Shallow wells or surface water sources would likely present different water profiles; this checklist focuses on deep groundwater typical in the area.
Maintenance Expectations for the C-Series Spotty Dishes & Glassware System
The system ships ready to configure and operates by addressing mineral content that causes spotting on dishes.
Regular routine checks of system components prevent buildup that could reduce performance.
Replacing treatment media and filters according to usage and manufacturer's guidance maintains effectiveness over time.
Differences Between Public System Records and Private Well Testing
Public water records show no health-based violations regarding minerals in Gwinnett County's aquifer samples, signifying overall compliance with standards.
Private well water quality can vary; only specific testing of your own water supply can determine exact mineral levels influencing spotting.
Government samples from multiple wells provide a regional picture but do not reflect individual household water characteristics definitively.
Interpreting Regional Measurements Against Federal Standards
The median calcium and magnesium concentrations found ranged from 62.1 to 118.0 mg/L, all below federal thresholds for safety.
These minerals contribute to what is commonly called water 'hardness,' which can cause spotting without indicating unsafe water quality.
Detection of these minerals is standard for groundwater in this aquifer and does not represent a violation or health risk.
Understanding this helps distinguish aesthetic effects like spotting from any safety concerns, guiding appropriate treatment choices.
If your household dishes continue to show spotting despite existing equipment, testing your water’s mineral content is a crucial step. The C-Series Spotty Dishes & Glassware System is designed to address mineral-related spotting effectively based on your specific water demand and characteristics.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-06-18. 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 320CRSL aquifer (Gwinnett County): 13 results from 9 wells, median 96.3 mg/L, range 62.1-118.0 mg/L; none above any federal threshold
