This week, homeowners in Lake County with large households face the important decision of choosing the correct class of water treatment to effectively manage hard water.
Hardness in Groundwater: How Calcium and Magnesium Enter Local Wells
In Lake County, the hardness of water primarily comes from naturally occurring calcium and magnesium dissolved from mineral deposits in the soil and rock of aquifer 110DUNED. According to U.S. Geological Survey samples taken in 2014 from six wells 25 to 30 feet deep, these minerals are consistently present in the area's groundwater. These constituents appear as a natural part of the regional aquifer's composition, reflecting the local geology rather than pollution or contamination.
Increased Household Demand Changes Hard Water Impact Patterns
For larger homes, water usage tends to be higher, leading to more frequent contact with hard water throughout plumbing and appliances. This means that the effects of hardness—such as scale buildup—can become more significant over time compared to smaller households. Properties used seasonally or as second homes may see varied impacts based on usage frequency and water exposure, which can influence the choice of treatment capacity and system configuration.
Untreated Hard Water Develops Scale and Efficiency Challenges Over Years
Leaving hard water unaddressed in a large residential property can lead to gradual scale deposits on fixtures and inside water heaters and pipes. While these effects are not immediate health issues, they can reduce system efficiency and lead to increased maintenance needs. Regular observation and timely treatment minimize these gradual changes, preserving plumbing condition and appliance performance.
Additional Considerations for Large Residential Operators Compared to Commercial Users
While commercial or industrial operators consider factors like high-volume processing and regulatory compliance, large households primarily focus on maintaining water quality for personal use and protecting household equipment. Questions about treatment often revolve around capacity to handle peak household demand and minimizing maintenance frequency rather than meeting intensive industrial standards.
Sample Size and Data Scope: What the U.S. Geological Survey Numbers Represent
The hardness data for Lake County's aquifer 110DUNED is based on 26 measurements collected from six different wells over a few months in 2014. This limited but regionally representative sample shows a median concentration of 772 mg/L hardness, with values ranging from 581 to 3,280 mg/L. None of these measurements exceeded any federal thresholds for health or safety. However, these figures represent the general groundwater characteristics and should not be used to infer the exact hardness in any individual well or home supply.
Given this regional data, the best step for homeowners considering water treatment is to conduct a direct hardness test on their own water supply. This single test will determine the precise hardness level and inform whether a system designed for a large home, such as the C-Series Hard Water — Large Home System, is appropriate. This equipment ships ready to configure for home use and is designed to address the levels of hardness typical in Lake County's aquifer 110DUNED.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2014-11-06. 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 110DUNED aquifer (Lake County): 26 results from 6 wells, median 772.0 mg/L, range 581.0-3280.0 mg/L; none above any federal threshold
