Reverse Osmosis (RO) Fact Sheet
Reverse osmosis (RO) is a process where water and contaminants are separated by passage through a thin semipermeable membrane. The membrane creates a barrier between water molecules and chemical or microbial contaminants as high-pressure forces water through the membrane, leaving contaminants behind. RO systems can remove most organics, metals and nitrate but are often used…

Ultraviolet (UV) Light Fact Sheet
Ultraviolet (UV) light utilizes radiation disrupting cellular DNA to kill microbes but is not utilized for removal of chemical contaminants. This treatment tool is generally used as a final step in reverse osmosis (RO) systems to improve the efficiency of microbe removal originating from the source water or that may grow in the POU system over time.…

Contaminant Level Occurrence Above the MCLG
The US Environmental Protection Agency (USEPA) sets a regulatory maximum contaminant level (MCL) or action level and a maximum contaminant level goal (MCLG) for all drinking water contaminants included in the National Primary Drinking Water Regulations (NPDWR). The MCLG is the maximum level of a contaminant in drinking water at which no known or anticipated…
