The EPA's public water system record for Brookfield Water Utility in Waukesha County shows no detections of perchlorate above the reporting level of 4.0 micrograms per liter in samples taken from 2003 to 2005. This record covers groundwater-supplied water serving about 29,070 people through over 10,000 connections within the city.
If you wonder what 'detected,' 'median,' and 'range' mean in this sampling record
In the EPA's monitoring data, 'detected' indicates that the measurement instrument measured perchlorate levels at or above the reporting threshold, which here is 4.0 µg/L. Not detecting perchlorate means measurements were below that threshold, but does not mean absolute absence. The 'median' is the middle value found if the detected values were listed in order; however, since no perchlorate was detected above the limit, no median above the threshold exists. The 'range' would describe the lowest to highest measured values but in this case reflects all results below detection.
If you consider how sample depth, well depth, or source type influence what to expect
Because Brookfield's water comes from groundwater sources, perchlorate concentrations can vary depending on well depth and local hydrogeological conditions. Shallower groundwater is sometimes more prone to environmental contamination influences, though no perchlorate above detection was found in this system's tests. The measurement data reflect the water utility's combined extraction points rather than any individual well. Sampling depth and well characteristics can cause variance in perchlorate levels, so individual household testing is necessary to determine personal tap water conditions accurately.
If you are a household weighing questions typically beyond commercial or industrial concerns
Unlike commercial or industrial settings that may focus on specific regulatory compliance thresholds or large-volume treatment capacity, a household user primarily asks: Is perchlorate present at a level that could affect family health or water taste? What treatment options are practical for residential scale? How will treatment affect water flow and routine use? These questions guide whether to choose a technology like the Fleck Perchlorate Filter, which directly targets perchlorate removal and ships ready to configure for household systems.
If you seek to understand what detected perchlorate levels mean against federal standards and what they do not
The EPA's record shows no perchlorate detected over 4.0 µg/L and no established federal maximum contaminant level (MCL) for perchlorate in public water systems. This means no regulatory violation or safety exceedance exists in the Brookfield water source as per the data. Detection is a measurement, not an indication of safety or contamination by itself. To confirm whether perchlorate is present in a specific household’s water and to what extent, testing of that home's water is essential.
If you want to know which fixtures, appliances, or water uses are affected first by perchlorate treatment
Perchlorate presence primarily impacts drinking and cooking water safety considerations. Treatment targeting perchlorate often involves point-of-entry filtration so all household water is treated, avoiding perchlorate consumption. Appliances and fixtures using untreated water, such as outdoor faucets, may remain unaffected and can be used separately if desired. The Fleck Perchlorate Filter system addresses this by delivering perchlorate-reduced water throughout the residence once configured on the household water supply.
If you wish to compare this water record to neighboring counties without overreading differences
Comparing Brookfield’s perchlorate data to nearby counties requires attention to the same scope of sampling dates, water sources, and detection thresholds. Adjacent counties may have different groundwater characteristics or monitoring histories but cannot be used to infer individual household water conditions in Brookfield. Each public water system record stands on its own and does not replace testing at the home level for personal decisions.
In summary, the EPA public water system record for Brookfield Water Utility in Waukesha County reports no perchlorate detections above the reporting limit during sampling from 2003 to 2005 across its groundwater supply. This data applies to the public water system as a whole, not to any single household. For individualized information on water quality, a home-specific water test is necessary. Those considering treatment to reduce perchlorate can evaluate options such as the Fleck Perchlorate Filter, which ships ready to configure for residential use.
