This article discusses how, as of January 2002, all large and most medium‐size surface water treatment plants are required by the US Environmental Protection Agency to report new data on turbidity measurements under the new Interim Enhanced Surface Water Treatment Rule (IESWTR). IESWTR individual monitoring and reporting requirements are discussed and include: conducting continuous monitoring at each filter; recording results of monitoring every 15 minutes and maintaining these records for at least 3 years; reporting to the state 10 days after the end of the month that this monitoring was conducted; and, calibrating turbidimeters using procedures specified by manufacturer.
