WaterOne’s state-of-the-art water quality lab runs over 120,000 tests on over 18,000 water samples each year to ensure the finest water reaches our customers’ taps. This includes monitoring for vinyl chloride, a known carcinogen.
Vinyl chloride is a byproduct of PVC pipes under rare and specific conditions. PVC pipes manufactured before 1975 may be a source of vinyl chloride leaching at long dead-end lines when water temperatures are above 50°F.
WaterOne uses a quality-grade PVC pipe safe for potable (drinking) water and has never detected vinyl chloride at unsafe levels in its water system.
Public safety is our priority. If WaterOne detects this or any other harmful substance in the water supply, we are required by law to notify the public. To ensure we reach you with important information about water quality and your water service, sign-up for Notify JoCo.
