DEFINITION OF TERMS MPCL = maximum permitted contaminant level NTU = Nephelometric Turbidity Unit CU = Color Unit mg/l = milligrams per liter or parts per million (ppm) µg/l = micrograms per liter or parts per billion (ppb) PCi/l = picocuries per liter ND@__ = not detected at a specified level * Trihalomethanes form as part of the water disinfection process and are monitored regularly to minimize their levels.	EXTEND YOUR KNOWLEDGE Find out about the quality of the water you drink and bathe in. If you live in a city or town, call your water department or water district and ask for a copy of the water quality test results for your area. Or use the Internet - many water agencies have the information available online. Go to a search engine such as Excite or AltaVista, and try entering the words "water quality" and the name of the place where you live.	.
