Description:
As a result of the new Lead and Copper Rule, some water utilities in the United States have begun or will soon begin corrosion demonstration studies. emonstration studies may include pipe rig/loop tests, metal coupon tests, and partial-system tests (fullscale). valuation of corrosion control treatment through testing may be accomplished by weight loss measurement, metal leaching, corrosion rate, or coupon surface inspection techniques. urrently, the U.S.Environmental Protection Agency (USEPA) is conducting several inhouse corrosion studies at it's Andrew W. Briedenbach Environmental Research Center,Cincinnati, Ohio. From the design stages to the operation of these studies, each has not been without problems. roblems have been noted and solutions have been derived and implemented. The purpose of this paper is to (1) briefly introduce 2 corrosion control studies being conducted at the EPA Research Facility, (2) discuss design and operational problems and considerations associated with each of the studies, and (3) present solutions to the problems. he experiences related in this paper may provide useful and time-saving insights into the design, operation, and interpretation of corrosion control studies to water utilities and suppliers faced with performing studies
