reducing exposure to lead," Cuppett said. "Linings and coatings should be considered one of the tools in the toolbox when dealing with lead service line replacement issues." Winning Solutions The project identified three particularly promising lead-abatement technologies and suggests them as the best options for utilities. "PET [polyethylene terephthalate] lining, epoxy coating, and polyurea/polyurethane coating are deemed especially promising and are therefore recommended for consideration," said Cuppett. The research also yielded some recommendations for utilities thinking of applying the technology. "During the planning process, public water systems should identify potential needs and/or opportunities for use of linings and coating to reduce short-term and/or long-term exposure to lead, such as avoiding disturbances of historic sites or structures, environmental damage, traffic disruption, and interference with or damage to other utilities," said Cuppett. With so much buried infrastructure residing beneath private property, LSL replacement and rehabilitation programs will only be as effective as utility collaboration with the public will allow. Choosing a coating technology is only half the battle; the remaining half is establishing an effective consumer outreach effort. "Public outreach will be an extremely important means of informing consumers and property owners about their 'shared responsibility,' including financial responsibility for replacing privately owned portions of LSLs," according to the research report. "Public water systems should provide information for consumers and property owners that emphasizes the importance of shared responsibility for minimizing exposure to lead, engages them in the planning process for the service area, clearly informs them about plans and progress to date, recommends actions they can or should take, and starts a dialog about possible financing options." Some utilities that can find the funding may decide that complete replacement is a better option, but for those that need to tackle lead contamination fast, without prolonged disruption of service, consider WRF's report. n wateronline.com n Water Innovations DISTRIBUTIONSYSTEMUPGRADES About The Author Peter Chawaga is the associate editor for Water Online.
