Dry Skin Challenges in Charleston County: Understanding Water Quality Impact

Understanding Secondary Standards Versus Health-Based Limits for Water Hardness

Laboratory reports list calcium and magnesium concentrations as indicators of water hardness

Government sampling in Charleston County's 120FLRD aquifer found median calcium and magnesium hardness at 312 mg/L with a range of 27.7 to 446 mg/L in wells 325 to 580 feet deep. These measurements reflect water hardness that affects feel and appearance but are not health-based violations.

Secondary standards address aesthetic and operational effects, not safety

Hardness levels influence water's feel on skin and its interaction with soaps and detergents, potentially contributing to dry skin. The observed hardness in Charleston County is below any federal health thresholds, confirming the water is not deemed unsafe by health authorities.

Maintenance Rhythm for Commercial Water Softening Equipment

Equipment like the Nelsen 300,000 Grain Skid-Mounted Commercial Water Softener requires regular monitoring

For commercial operations, maintaining consistent softening capacity ensures control over hardness-related water effects. The Nelsen 300,000 Grain unit ships ready to configure and supports ongoing management of hardness at scale.

Scheduling replenishment and system checks is essential

The large grain capacity means less frequent replenishment cycles but routine attention to system function helps maintain effective water conditioning that can alleviate dry skin issues on a commercial scale.

Additional Questions for Commercial Operators

What is the volume of water used daily in the operation?

High consumption affects sizing and upkeep plans for commercial softening equipment, influencing efficiency in controlling hardness.

Is water hardness consistent or variable in the supply?

Testing multiple points over time helps determine if hardness fluctuates, affecting treatment strategy and system adjustments.

Are there secondary impacts on equipment or processes beyond drying skin?

Assessing the full scope of hardness effects ensures comprehensive management of water quality within commercial activities.

Considerations for Large or Seasonal Commercial Properties

How does intermittent occupancy affect system maintenance?

Seasonal or second properties may need tailored schedules for softener operation and care to avoid stagnation or performance lapses.

Is water storage used, and how does it interact with hardness levels?

Storage tanks can change water chemistry over time; monitoring hardness post-storage is recommended for consistent treatment results.

Long-Term Effects of Untreated Hardness in Commercial Water

Persistent hardness can lead to skin dryness complaints among staff or customers

Though not a health hazard, untreated hardness often reduces water comfort and may increase the need for moisturizers or other skin care.

Hard water contributes to scaling in pipes and equipment

This can elevate maintenance demands and operational costs, indirectly affecting commercial efficiency.

What Charleston County Area Data Does Not Determine

These regional hardness figures do not reveal the exact water quality of any individual well or tap

Local testing of your specific water source is required to establish precise hardness levels and tailor treatment plans accordingly.

Detection in regional samples does not imply any safety violation

All recorded hardness levels in the 120FLRD aquifer samples were below federal health thresholds and do not indicate unsafe conditions.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2018-08-16. 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 120FLRD aquifer (Charleston County): 3 results from 2 wells, median 312.0 mg/L, range 27.7-446.0 mg/L; none above any federal threshold
