IESWTR Targets Poorly Performing Filtration Plants

摘要

The Interim Enhanced Surface Water Treatment Rule (IESWTR) establishes individual filter turbidity monitoring requirements for systems serving 10,000 or more people. If the turbidity in any filter exceeds 2.0 ntu for two consecutive months in two consecutive measurements taken 15 minutes apart, a comprehensive performance evaluation (CPE) is required. This requirement is intended to identify and correct poorly performing filtration plants.
