Abstract |
If a waterborne disease outbreak is the result of problems at a treatment plant, a thorough and careful evaluation of both process equipment and operating procedures is needed. The evaluation should be done in a series of actions, explained in the paper. A thoughtful investigation involves checking records at the water utility and perhaps other sources, reviewing conditions of equipment, basins, etc., making informed judgments on probable efficacy of processes as they are functioning, and checking on procedures being applied by the operating staff. Many papers have been written concerning proper design and operation of water filtration plants and disinfection facilities. The manuscript cites numerous references that provide guidance on appropriate ways to upgrade and operate treatment plants. |
