Myth: Detectable perchlorate in your household water always means a health hazard
The EPA’s Unregulated Contaminant Monitoring Rule (UCMR) samples for perchlorate in Cassatt’s public water supply show one detection out of 17 samples above 4.0 micrograms per liter at 4.5 micrograms per liter. There is no health-based violation recorded for this system. A detection is a measurement, not a health advisory. Without a local water test, a household cannot know its own perchlorate concentration. The EPA record for the public water system serving Cassatt indicates groundwater as the source, with no violations related to perchlorate.
Myth: Sampling depth and well depth do not affect perchlorate levels
Water quality can vary with sample location. Shallow wells or surface water sources could carry different perchlorate levels than deeper groundwater wells. Cassatt’s public water system draws from groundwater, which generally shows more stable contaminant levels than surface water. If your household uses a private well, testing water at the tap is the only way to verify perchlorate concentration for your specific depth and source.
Myth: Plumbing material or home age changes perchlorate presence in water
Perchlorate is a dissolved inorganic contaminant. It does not originate from plumbing materials or pipe age. While older plumbing can contribute other water quality issues, perchlorate presence or absence is determined by the source water. Therefore, household plumbing aging or material type does not affect perchlorate levels but may influence other treatment considerations.
Myth: Treatment sizing is standard regardless of household water use
Treatment capacity should align with your household’s daily water demand. Larger families or homes with higher water use need filters capable of handling greater volumes to maintain effectiveness. Knowing your average daily water use—calculated from fixture counts or water bills—helps select the right filter capacity. Without matching capacity, perchlorate removal performance can decline.
Myth: All household fixtures and appliances are equally affected by perchlorate
Perchlorate, being a dissolved compound, travels with water through all fixtures. However, appliances that consume large amounts of water, such as washing machines or dishwashers, may stress treatment systems more quickly. Point-of-entry filters that treat water for the entire household ensure consistent reduction before water reaches any fixture.
Myth: Seasonal use or multiple homes do not change perchlorate treatment needs
Seasonal properties or second homes with intermittent water use require filters that accommodate fluctuating demand and potential stagnation issues. Treatment systems must maintain readiness despite periods of low or no water flow. Larger households versus smaller ones also differ in total water volume, guiding treatment sizing decisions.
For households in Cassatt, Kershaw County seeking effective perchlorate reduction tailored to daily water use, the Fleck Perchlorate Filter ships ready to configure and address this specific water concern based on measured household demand.
