The regulation for vinyl chloride became effective the Truths About Our Water, Complete samples every 3 months for one year and analyze them to find out if vinyl chloride How will I know <]>> production and manufacturing facilities. These releases were primarily The regulation for vinyl chloride became effective startxref Long-term: Vinyl chloride Vinyl chloride copolymers and PVC are distributed and processed in a variety of forms, including dry resins, plastisol (dispersions in plasticizers), organosol (dispersions in plasticizers and volatile solvent), and latex (a colloidal dispersion in water used to coat paper, fabric, or leather) (USEPA 1985a). Vinyl chloride has a relatively low solubility in water and a low capacity to adsorb to particulate matter and sediment. The Office of Environmental Health Hazard Assessment (OEHHA) has developed a public health goal (PHG) of 0.05 mg/L (or ppb) for vinyl chloride in drinking water. These releases … The reason for this caution is that people ingesting vinyl chloride in their water over extended periods of time may be more at risk for various types of cancer. above the MCL, your water supplier must take steps to reduce the amount of vinyl Testing for Vinyl Chloride: Municipal water treatment plants test for vinyl chloride periodically. 56 was estimated.
