Government Sampling Summary
Number of perchlorate samples collected
The Martinsburg City public water system collected 17 perchlorate samples between 2002 and 2005 as part of the EPA's Unregulated Contaminant Monitoring Rule (UCMR1).
Detection results and reporting level
None of these samples detected perchlorate above the reporting level of 4.0 micrograms per liter (µg/L). This means measurements were below the level at which reporting is required, not that perchlorate is absent.
Implications of limited sample size
Seventeen samples represent a limited dataset from a system serving over 16,000 people. A small number of samples means the data may not capture all potential variations or localized changes that could affect a specific household’s water.
How Documented Treatment Technology Addresses Perchlorate
Function of the Autotrol Perchlorate Filter
This filter uses an Autotrol system designed specifically to reduce perchlorate levels in water. It operates by removing perchlorate ions through a selective filtration process.
Expected performance considerations
The system ships ready to configure for residential water lines and does not require additional plumbing services. It is recommended for households wishing to address perchlorate as identified by local or personal water tests.
Sources of Perchlorate in Martinsburg’s Surface Water
Origin of perchlorate
Perchlorate is typically found in the environment due to its use in industrial and agricultural processes. In this region, it can enter surface water sources via atmospheric deposition and runoff.
Pathway to household water
The Martinsburg public water system uses surface water as its source, meaning perchlorate detected in the source water can be carried through the distribution system to consumers.
Important Information to Record Before Seeking Help
Source and age of your water supply
Note whether your water comes from the public system or a private well, and gather any past water quality reports available for your address.
Any household water treatment currently in use
Document any filters or treatment devices already in place which may affect perchlorate or other contaminants.
Recent water quality test results
If you have tested your water privately, record the date, location, and specific lab results for perchlorate and other relevant substances.
Seasonal and Multi-Year Variation in Monitoring Data
Time range of sample collection
The government sampling for perchlorate was conducted from October 2002 through October 2005, covering multiple years to capture potential variations.
Potential changes not covered
There are no recent publicly available data beyond 2005 for perchlorate in Martinsburg’s system. Changes in land use, industrial activity, or water treatment processes since then may affect current levels.
Next Steps for Homeowners in Martinsburg
The recommended action is to order a comprehensive water test specifically including perchlorate analysis for your own supply. Only this can confirm your household's actual perchlorate concentration and clarify if treatment is beneficial.
