If Your Laboratory Test Reports Perchlorate Results

A certified laboratory test for perchlorate typically measures the concentration in micrograms per liter (µg/L). This test result indicates the specific amount of perchlorate detected in your home's water sample at the time of testing. However, it does not imply any regulatory violation or health hazard by itself. The lab report helps you understand your household water quality but must be interpreted in the context of local water data and guidelines.

If You Compare Measured Levels to Federal Standards

Currently, there is no federal maximum contaminant level (MCL) established for perchlorate. According to data from the San Antonio Water System serving Bexar County, perchlorate was not detected above the reporting level of 4.0 µg/L in any monitored sample. This means that while perchlorate can be present at low levels, it has not been recorded in treated public water at levels requiring regulatory action. Detected levels do not equate to safety concerns or violations and should be considered alongside practical water use needs.

If You Are Determining What to Test or Check First

Start by reviewing whether your water source is municipal or private:

• If municipal, consult the local water quality report, which in this region shows no perchlorate detections above reporting levels.
• If private well water, a certified lab test specifically for perchlorate is advisable since public system data does not apply to private wells.

Evaluating the entire water system's data before individual testing can guide cost-effective decision-making on whether perchlorate treatment is needed.

If You Consider How Perchlorate Is Introduced into Water in Bexar County

Perchlorate in this area primarily originates from surface water sources subject to environmental factors and industrial activities that can release perchlorate compounds into the watershed. It can infiltrate groundwater or distribution systems through runoff or discharge. The San Antonio Water System relies on surface water and maintains monitoring programs that have found concentrations largely below detection limits, reflecting effective source control and treatment.

If You Are Evaluating Treated Household Water Quality with a Filtration System

The Fleck Perchlorate Filter is designed to reduce perchlorate levels in household water through advanced filtration technology. When configured for residential use, it targets perchlorate removal specifically while maintaining water clarity and taste. Using this system can result in water at the tap with significantly lowered perchlorate concentrations, supporting household water quality preferences and any precautionary measures you choose to take.

Remember, system-wide monitoring data from San Antonio Water System reflects aggregated results across many connections and sampling points. Your home's water quality can only be confirmed through a dedicated laboratory test of your specific source. The Fleck System ships ready to configure for your household water conditions.

Government water quality records for the San Antonio Water System (TX0150018) in Bexar County, TX, are publicly available through the EPA’s Safe Drinking Water Information System (SDWIS). These records show zero health-based violations and demonstrate perchlorate levels consistently below reporting limits in this public supply.
