The Surface Water Treatment Rule (SWTR) requires that all community and noncommunity water supply wells, springs, and infiltration galleries be evaluated to determine whether they are under the direct influence of a surface water. Those groundwater supplies that are found to be under the direct influence of a surface water will be subject to the requirements of the SWTR. This determination will have a significant impact on many existing water utilities and on the development of new supplies. The guidance manual for the SWTR ("Guidance Manual for Compliance with the Filtration and Disinfection Requirements for Public Water Systems Using Surface Water Sources," AWWA order number 20271) provides a general outline of a procedure that can be used to make the determination of direct influence. This procedure was applied to two groundwater supplies. Includes 2 references, figures.
