Primary Contaminant Treatment Solutions

Some water quality concerns require specialized treatment technologies beyond traditional filtration and conditioning equipment. Lancaster Water Group has products designed to address contaminants that may affect the safety, quality, and usability of your household water supply. Whether your water is at risk for arsenic, nitrate, PFAS, lead, or bacteria, Lancaster offers targeted treatment solutions engineered to deliver reliable performance and peace of mind. Our systems utilize proven treatment technologies to help homeowners improve water quality throughout the home.

Arsenic

Arsenic is a naturally occurring contaminant that can be found in groundwater and private wells. Specialized treatment systems help reduce arsenic concentrations, providing homeowners with greater confidence in the quality and safety of their drinking water.

Anti-Scale

Calcium creates scale in pipes, on appliances and other plumbing surfaces, leading to concerns such as higher energy costs and untimely repair bills. The Lancaster CityGuard LTE system utilizes an up-flow non-electric valve, plate technology distribution tank, and anti-scale media. The anti-scale media pulls the hardness minerals of calcium and magnesium out of the water, transforming them into “nano” crystal particles. These particles are so small they will make their way through plumbing systems without attaching to pipes, fixtures, valves or heating elements.

X-Factor Series CityGuard

The CityGuard LX Diamond Line is designed to deliver complete, whole‑home water treatment by combining advanced filtration with EcoSense media for powerful, salt‑free scale protection. As water passes through the system, EcoSense transforms calcium and magnesium into tiny, harmless crystals that stay suspended in the water instead of sticking to pipes and appliances. This helps prevent and reduce scale buildup while additional filtration media work to improve water quality by reducing chlorine, contaminants, and issues affecting taste, odor, and clarity. The result is high‑performance water treatment that protects your plumbing, enhances water quality, and helps extend the life of your home’s water‑using systems.

Up-Flow CityGuard

CityGuard Up‑Flow systems offer a simple, efficient approach to water treatment, powered by EcoSense media for reliable, salt‑free scale prevention. As water flows through the system, hardness minerals are converted into harmless crystals that remain suspended in the water, preventing them from forming scale on plumbing and appliances. These systems are designed for easy, low‑maintenance operation while still helping improve water quality and reduce buildup throughout the home. With their straightforward design and effective performance, Up‑Flow systems provide homeowners with an easy way to protect plumbing, maintain efficiency, and enjoy better water every day.

Reverse Osmosis

The Guardian Reverse Osmosis water system reduces minerals and contaminants found in common tap water. A four-stage system filters water at the molecular level resulting in clean, fresh, and better-tasting water.
Our systems direct the flow of water through each filtration step without the need for tubes or fittings. This design also contains major parts like the water saving automatic shut-off, drain control and safety check valve, making it easy to maintain and service.

Reverse Osmosis

How Does the R.O. System Work?
Reverse Osmosis (R.O) in one of the most convenient and economical methods of reducing unwanted contaminants in your drinking water. Reverse Osmosis is the process by which water molecules are forced, by household pressure, through a semi-permeable membrane. Most of the impurities and other contaminants are rinsed to the drain while the refined water is routed to a special holding tank.

Chemical Feeders

The disinfection of water and the treatment of pH imbalance by chemical injection are reliably accomplished with the Lancaster Chemical Pump Series. Chemical feed pumps are usually installed in connection with private well systems. Chemical solution feeders may be used to introduce solutions into the household water supply for treatment purposes. Chlorine or potassium permanganate for the oxidation of iron and manganese, soda ash for the neutralization of acid water and polyphosphates for the control of soluble iron can all be used with these feeders.
