Including filter system and high-performance 1,1-Dichloroethylene filter.
1,1-Dichloroethylene is a volatile organic compound (VOC) that can enter groundwater when industrial solvents or related chemicals make their way into drinking supplies. Because it evaporates readily, it can move from water into the air in your home during showers, laundry and dishwashing, so inhalation as well as ingestion are pathways to consider. It’s usually invisible and without a noticeable taste or odor, which is why testing is the only reliable way to know whether it’s present; if test results show elevated levels, treating the water where it comes into your Rock Creek house is a sensible next step.
VOCs such as 1,1-dichloroethylene are often measured at very low concentrations and can fluctuate, so clear water isn’t a guarantee of safety. Many Rock Creek families choose to reduce exposure for everyday activities—cooking, brushing teeth, bathing—not just at a single faucet. A point-of-entry, whole-house solution provides treated water to bathrooms, the kitchen and appliances, giving consistent protection throughout the home instead of treating only one outlet.
For treating 1,1-dichloroethylene, the most effective single-filter whole-house option is a granular activated carbon (GAC) system. GAC media adsorbs a wide range of VOCs as water passes through the carbon bed, and when installed at the main water entry it treats water before it reaches showers, sinks and household appliances—reducing both ingestion risk and the chance that VOCs will volatilize into indoor air.
Sizing a GAC tank correctly is important because sufficient contact time between water and carbon is what enables reliable VOC removal, and the system needs to match your home’s flow rate and usage patterns. Carbon media will eventually become exhausted, so routine replacement or re-bedding is necessary to maintain performance. Using a prefilter ahead of the GAC can protect the carbon from sediment that would otherwise reduce effectiveness and raise pressure loss. Mr. Pure Water can help Rock Creek homeowners choose a whole-house carbon setup tailored to their house and focused on lowering 1,1-dichloroethylene.
