Lost capacity problems and associated water quality problems, including total coliform problems, will be described and methods of rehabilitation will be discussed. Complying with the Revised Total Coliform Rule is often not as simple as disinfection of wells, but more importantly requires that the well be cleaned and kept clean on a periodic basis. The occurrence of total coliforms most often do not suggest contamination of water wells, but can suggest that the well needs to be cleaned. Novel ideas and understanding about well problems and solutions will be presented, based on many years of experience. With ever increasing energy costs, there is increasing pressure to look at ways to reduce cost. New effective and economical methods of well maintenance will be presented with case studies of cost savings. Case studies will also be presented on solving difficult total coliform issues on wells.
