The public water system serving about 20,000 people in El Paso County, Colorado, including the Security WSD (CO0121775), has been monitored for perchlorate presence. According to federal monitoring conducted from 2001 to 2005, none of the 33 samples from this system detected perchlorate above the reporting threshold of 4.0 micrograms per liter. These figures reflect the overall water supplied, not the water from any specific household or well, and no health-based violations related to perchlorate are on record for this system.
If perchlorate remains untreated over several years
Perchlorate is a chemical of concern because it can interfere with iodine uptake in the thyroid gland, potentially affecting hormone production. Long-term exposure at elevated levels may impact thyroid function. However, the detection data for the Security WSD system does not show perchlorate at levels requiring regulatory action. Untreated perchlorate at significantly raised concentrations may cause taste issues or staining, but those effects tend to be secondary considerations. Testing your own water is necessary to determine if perchlorate is present in your household supply and at what concentration.
If you confuse perchlorate with similar water quality challenges
Other common constituents in water, such as nitrates or chlorides, can also affect taste or water chemistry but have different sources and health considerations. Unlike these, perchlorate specifically impacts thyroid function and is monitored separately. Measurements from the public system show no perchlorate detections above reporting levels, distinguishing it from other constituents that might require a separate type of treatment or concern. It is important to differentiate these to avoid mistaking perchlorate issues for unrelated water conditions.
If your household is large, a second home, or seasonal property
A household with multiple residents or intermittent occupancy affects water use and treatment demands differently. For a large household, perchlorate treatment capacity should align with daily water consumption. For second or seasonal homes, periods of non-use do not reduce the need for effective treatment once water use resumes. If your previous treatment equipment has failed, assessing your household's water usage will help determine an appropriate replacement that can deliver consistent perchlorate reduction over time.
If you consider the scope and sample size behind the perchlorate data
The 33 samples cited in the federal occurrence survey represent the overall pattern in the Security WSD system but are not a guarantee of the water quality at any particular tap. The survey covered a defined period several years ago and focused on public water supply points, not private wells. Consequently, individual water should be tested to confirm perchlorate levels. A small number of samples can indicate a trend but cannot substitute for frequent or site-specific monitoring.
If the documented technology is used to treat perchlorate in your home water
The C-Series Perchlorate Filter system addresses perchlorate by reducing it through proven filtration methods. Once water passes through this technology, perchlorate concentrations can be lowered to levels consistent with regulatory expectations and user comfort. The treated water at fixtures shows improvement, supporting regular household use without the previous equipment failure concerns. The system ships ready to configure and fits the demand level identified by your household water consumption measurements.
If you want to understand how public water system records differ from private well testing
Public water system records provide data averaged over many points and times, reflecting overall water quality but not individual circumstances. Private wells may have different sources, treatment needs, and concentrations of perchlorate or other constituents. Testing private well water at the point of use is essential to determine the actual treatment needs and the appropriate technology. These records do not replace personal water analysis but do offer insight into regional water quality trends.
For households in El Paso County facing perchlorate treatment challenges after equipment failure, the C-Series Perchlorate Filter offers a documented solution tailored to measured household demand. It enables renewed treatment capability designed to reduce perchlorate effectively at the tap.
