What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
In Hennepin County's aquifer 112GSSG, government groundwater sampling found chloride in all 23 tests from 20 wells. 'Detected' means the measuring instruments found the chemical; it shows presence but not whether it exceeds any limits. 'Median' is the middle value of measured chloride levels, here 76.5 mg/L, indicating a typical concentration found in this area’s shallow wells of 9 to 29 feet deep. The 'range' from 2.28 to 328.0 mg/L shows the lowest and highest measurements recorded, evidencing variability among different wells but not indicating individual well conditions.
Maintenance Rhythm of the Documented Technology in Plain Terms
The Fleck Corrosive Water Damaging Pipes Filter ships ready to configure for your home’s water system and requires regular attention to continue protecting your plumbing. Periodic regeneration cycles refresh the filter media, and routine checks ensure the system functions correctly by addressing corrosive elements that can deteriorate pipes. Following manufacturer guidelines for these maintenance steps helps maintain water quality and equipment effectiveness over time.
How Public-System Records Differ from Private-Well Testing in What They Establish
Public-system water quality records reflect the average conditions and range found across multiple wells or sources serving a community; they are not direct measurements of a single household’s water. Private-well testing, in contrast, reveals the specific chemistry of your home's water supply. Public records provide valuable regional context but cannot substitute for individual testing necessary to identify any unique or localized water quality concerns at your residence.
What a Certified Laboratory Test for This Constituent Reports and How to Read It
A certified lab test for chloride in your water sample reports the actual concentration in milligrams per liter (mg/L). It provides precise data about your private well or tap water at the time of testing, which should be compared with regional data for context. Such a test is the only way to know your own water chemistry accurately, as regional sampling does not predict individual well conditions.
How Seasonal or Multi-Year Variation Shows in the Record
The sampling data for chloride in Hennepin County’s aquifer 112GSSG spans over five years, from July 2011 to September 2016. This multi-year record captures fluctuations across seasons and various conditions affecting groundwater quality. The wide range in measurements indicates that chloride levels can vary substantially over time and between wells, highlighting the importance of ongoing monitoring for any specific water source.
In summary, the U.S. Geological Survey’s records describe chloride levels detected in multiple shallow wells in Hennepin County’s aquifer 112GSSG over a five-year period. This regional data informs about the typical range and presence of constituents linked to corrosive water but does not identify individual well quality. For precise household water conditions, certified lab testing is advised. The Fleck Corrosive Water Damaging Pipes Filter is designed to address corrosive water effects in residential settings and requires routine maintenance to perform effectively.
