Government sampling of the Parsippany-Troy Hills Water Department system in Morris County found no perchlorate detections above the 4.0 µg/L reporting level between 2002 and 2005 in surface water sources supplying roughly 50,400 residents. This public water system record covers 15,000 connections and reflects a federal occurrence survey, not compliance monitoring.
Does Plumbing Material or House Age Affect Perchlorate Levels Independently of Source Water?
Perchlorate primarily enters water supplies through environmental sources rather than from household plumbing components. Plumbing materials and the age of your home's pipes generally do not contribute perchlorate to your water. Therefore, even older homes or those with certain plumbing systems are not inherently more likely to have perchlorate presence stemming from their internal infrastructure. The source water and treatment practices are the main determinants.
How Can I Determine the Treatment Capacity My Household Needs?
To choose the right treatment, first consider your household's daily water usage. Typical families use between 50 to 100 gallons daily per person. Treatment capacity should at least meet this demand considering peak usage. The absence of detected perchlorate over several years in the system suggests lower treatment needs, but individual well or tap water testing is necessary to confirm local conditions. Once you know your home’s water flow and perchlorate concentration, you can evaluate the system size needed to treat that volume effectively.
How Does the Fleck Perchlorate Filter Work to Address Perchlorate?
The Fleck Perchlorate Filter uses specific filtration media and technology designed to reduce perchlorate levels by ion exchange or adsorption processes. It captures and removes perchlorate molecules from water as it passes through the filter, protecting household water quality. This equipment ships ready to configure for residential use and offers a documented method for perchlorate reduction when household testing shows its presence above desired concentrations.
How Should Homeowners Interpret the Median and Range in the Government Record?
The Parsippany-Troy Hills water record showed zero perchlorate detections out of 30 samples, meaning all results were below the 4.0 µg/L reporting limit. The median and range here indicate no measurable perchlorate presence during the sampling period rather than an exact concentration. This means the source water did not have perchlorate at levels detectable by the EPA’s methods at that time, though conditions could change and testing at your specific point of use is recommended for certainty.
What Are the Consequences of Leaving Perchlorate Untreated if Present?
If perchlorate is found in household water, prolonged exposure at high levels may impact thyroid function, as perchlorate can interfere with iodine uptake. However, the Parsippany-Troy Hills system record shows no perchlorate detections, suggesting this is not a widespread issue locally. Without presence confirmed by testing, treatment may not be necessary. If relevant concentrations exist in a private source, leaving perchlorate untreated could have subtle health implications over time, so appropriate filtration reduces potential risks.
