Myth: The drinking water in Bexar County homes has high perchlorate levels due to its source type or sample depth
Many think that perchlorate contamination is directly tied to how deep a sampling is taken or which water source is used. However, the public water system record for the San Antonio Water System, serving Bexar County, based on EPA monitoring from 2001 to 2005 across 67 samples, reports zero detections of perchlorate above 4.0 micrograms per liter. Since the water supply is surface water, this data reflects the system's broad water quality and does not indicate perchlorate presence linked to sampling depth or source. Individual homes may differ, but any specific perchlorate concentration would require a direct water test at the point of use.
Myth: Household fixtures and appliances are immediately affected by perchlorate if detected in the water supply
Concerns often arise that if perchlorate is present, household water fixtures or appliances will be impacted first. Perchlorate does not degrade typical household plumbing or appliances, nor is it known for causing scale, corrosion, or staining. Rather, it is a chemical of concern primarily regarding ingestion. Areas such as drinking water taps or kitchen uses where water is consumed or prepared would be the main focus for treatment consideration, not fixtures or appliances sensitive to water chemistry changes.
Myth: Larger or seasonal households need different perchlorate treatment approaches than standard homes
The size or seasonality of a household does influence how much water is used daily, but the treatment approach for perchlorate is principally about the total volume of water to be treated. A larger household or a property used seasonally will have different water demand patterns that affect how treatment capacity should be sized. Regardless of household size, effective perchlorate treatment systems like the Fleck Perchlorate Filter must be matched to expected daily consumption to ensure proper performance.
Myth: Starting with advanced laboratory testing for perchlorate is necessary before addressing treatment
Before choosing a treatment method, it is wise to rule out simpler possibilities through initial checks such as confirming water sources and reviewing public system data. The San Antonio Water System's perchlorate monitoring results provide a baseline understanding of local water quality. If there is any uncertainty or special concern, collecting a water sample from the specific home and submitting it for lab analysis focused on perchlorate is the definitive step to assess need for treatment and system sizing.
Myth: Treatment capacity can be selected without considering the household's daily water demand
Choosing a perchlorate treatment device without understanding daily water usage risks undersizing or oversizing equipment. Treatment capacity must align with the household's water withdrawal to maintain effectiveness and avoid operational issues. Calculating typical daily consumption, factoring in peak uses, and considering any seasonal fluctuations are essential in selecting treatment solutions such as the Fleck Perchlorate Filter, which ships ready to configure for residential settings.
In summary, public water system data from Bexar County shows no perchlorate detections above the reporting level, which informs expectations based on source and sampling depth. Households should focus testing on their own water to confirm conditions, consider daily water use when choosing treatment, and remember that treatment effectiveness depends on matching capacity to demand. The Fleck Perchlorate Filter offers a documented technology for managing perchlorate in residential water when needed.
