    Abstract: A method includes transporting water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through a pipe. The method includes forming a polyethylene resin using a catalyst, mixing the polyethylene resin with an antioxidant, wherein the antioxidant is a thioester, a hindered amine light stabilizer or 1, 3, 5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene to form a resin/antioxidant mixture, extruding pipe from the resin/antioxidant mixture, and flowing water containing chlorine dioxide, chlorine, chloramines, or hypochlorites through the pipe. An extruded article is adapted for use in containment and/or transport of water that contains chlorine dioxide, chlorine, chloramines, or hypochlorites. The extruded article includes a polyethylene resin and an antioxidant. The antioxidant is a thioester, a hindered amine light stabilizer or 1, 3, 5-trimethyl-2,4,6-tris (3,5-di-tert-butyl-4-hydroxybenzyl) benzene.
