Household water treatment in Olney, Maryland.

Olney is in WSSC Water's Montgomery County area, most of which WSSC says receives its water from the Potomac River, and the 2025 tap analysis for the Potomac plant lists fluoride at an average of 0.7 mg/L.

UV and chlorine at the plant

WSSC has added ultraviolet disinfection at its filtration plants as an extra barrier, on top of chlorine. An Olney assessment starts from WSSC's published data for your supply and from what you notice at your sinks and showers.

The way we work does not change from house to house. We look up the public data on your water, tell you what your home actually needs, and put it in for one all-in price.

What we fit in Olney homes

• A softener and carbon filter for the whole house, fitted on your main line, as the flagship bundle starting at $2,699 installed.
• Reverse osmosis under the sink for drinking water, and the part of the setup that deals with PFAS.
