Scope and Limits of Local Water Sampling Data
Water quality information from New Hanover County's aquifer 211PEED is derived from a set of 66 groundwater samples taken from 46 different wells between 2012 and 2017. These wells range in depth from 42 to 220 feet and represent a regional snapshot rather than an individual household's water composition. This data provides an overview of the presence of certain constituents, such as chloride, but it does not specify the exact condition of any one home's water supply. Homeowners must rely on direct testing of their own well or tap water for precise analysis.
Additional Considerations for Commercial Water Users
While residential households focus primarily on water quality impacts related to daily use and plumbing integrity, commercial or industrial operators often face broader challenges. These include assessing water corrosion effects on large-scale piping systems, machinery compatibility, and potential impacts on manufacturing processes. The data used by residential users offers a narrower perspective centered on household plumbing and appliance preservation.
Improvements at the Tap After Using the Documented Solution
Water that is corrosive can gradually damage pipes and fixtures, potentially causing leaks or reduced lifespan of household plumbing. The Pentair Corrosive Water Damaging Pipes Filter is designed to condition water to mitigate corrosive effects once configured in the water treatment setup. After implementation, homeowners may notice diminished signs of corrosion-related wear and enhanced protection for their plumbing system. This technology helps maintain water quality at the point of use by addressing corrosion factors documented in regional data.
Interpreting the Median and Range of Regional Chloride Measurements
The recorded median chloride concentration in New Hanover County aquifer samples is 68.05 mg/L, with values spanning from 10.8 mg/L to 919.0 mg/L. These figures show that chloride is consistently detected, though at widely varying levels depending on the specific well sampled. Such variation reflects natural differences in aquifer conditions and geological formations rather than uniform water quality across all residences. Understanding this range enables homeowners to contextualize their own water testing results against regional data.
Chloride Levels and Federal Guidance: What the Data Does and Does Not Indicate
Within the sampled wells, six results exceeded the secondary aesthetic standard of 250 mg/L for chloride. This threshold relates to taste, staining, and corrosivity concerns but is not a health-based regulatory limit. Exceeding this aesthetic level does not imply a health risk or violation of water quality laws. It is important for homeowners to recognize that detected chloride concentrations above this secondary standard indicate possible aesthetic effects, such as metallic taste or pipe staining, but do not reflect unsafe water.
In summary, the regional chloride data from 46 wells and 66 samples collected in New Hanover County's aquifer 211PEED offers valuable context for household corrosive water concerns. It highlights the presence and variability of chloride, a contributor to water corrosivity, while clarifying that individual water conditions require direct testing. The Pentair Corrosive Water Damaging Pipes Filter provides a practical solution to help manage and reduce corrosive effects identified through such regional analysis.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-05-25. 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 Chloride in the 211PEED aquifer (New Hanover County): 66 results from 46 wells, median 68.05 mg/L, range 10.8-919.0 mg/L; 6 above an AESTHETIC secondary standard only (secondary standard 250.0 mg/L (aesthetic)) - not a health finding
