The U.S. Geological Survey has sampled groundwater from two wells in Cumberland County’s aquifer 112OTSH, with 14 chloride results measured between 2010 and 2017. These samples, taken from depths of 22 to 38 feet, found chloride levels consistently detected from 21.4 mg/L up to 91.8 mg/L, with a median of 60.95 mg/L. No test exceeded any federal limit. This data reflects the area's groundwater chemistry but does not indicate the specific condition of any one household's water.

Household Symptoms That May or May Not Indicate Corrosive Water

Presence of unusual metal taste or metallic staining on fixtures

Frequent pinhole leaks or premature plumbing failures

Discoloration or blue-green staining on copper pipes

Absence of visible rust or hard water scale buildup (which suggests other issues)

No direct link between chloride levels reported and immediate safety concerns

Maintenance Rhythm of the C-Series Corrosive Water Damaging Pipes Filter

Filter components require periodic cartridge changes based on household water use and water test results

System shipments arrive ready to configure; routine maintenance is user-managed

Regular water testing is advised to monitor changes in corrosivity and treatment effectiveness

Order of Actions to Rule Out Other Causes Before Testing Water Chemistry

Inspect visible plumbing and fixtures for leaks or stains

Evaluate water taste and appearance for metallic or other unusual characteristics

Check for common household causes such as water heater or appliance issues

Collect water samples to submit to a certified laboratory for pH, alkalinity, and corrosivity testing

Understanding the Local Chloride Range Versus Federal Guidelines

All local aquifer 112OTSH chloride results were below federal secondary standards for taste and corrosion control

Detection of chloride does not imply water is corrosive or unsafe; it is one factor among many in water chemistry

Chloride impacts include potential for increased conductivity and minor contributions to corrosion tendencies

How Water Treated by the C-Series System Differs at the Faucet

Reduction of water corrosivity minimizes damage to pipes and plumbing fixtures

Less metal leaching into water improves taste and protects household plumbing longevity

The filter helps maintain stable water conditions, contributing to consistent water quality

The USGS record for Cumberland County aquifer 112OTSH groundwater spans multiple samples from two wells over several years, providing a regional snapshot of chloride presence. For detailed water quality of your household, testing by a certified laboratory is necessary. More information is available through the U.S. Geological Survey monitoring site.
