The U.S. Environmental Protection Agencys (EPA) Clean Charles 2005 Initiative seeks to restore the Lower Charles River (from the Watertown Dam to Boston Harbor) to fishable and swimmable conditions by Earth Day 2005. Progress toward this goal is already evident; according to a Charles River Watershed Association (CRWA) Monthly Water Quality Sampling Data Report, the Lower Charles River met swimming standards for bacteria approximately 75% of the time in 1999, up from just 19% in 1995. To explore means for improving swimming beach water quality, the New England Interstate Water Pollution Control Commission (NEIWPCC) received a grant from EPA New England to conduct a preliminary evaluation of the Gunderboom Beach Protection System (BPS) during the summer of 2000, as well as a follow-up study during the summer of 2002. The 2000 project was conducted over two, three-day periods in the Lower Charles River, near Magazine Beach in Cambridge. The results were generally encouraging and highlighted the potential for the BPS technology to be effective for Charles River swimming beach applications; however, some results were less conclusive and even counterintuitive to the simple physics of filtering particulates out of water. In order to confirm the ability of the BPS technology to provide a safe swimming area in the Lower Charles River, a follow-up study was conducted in 2002. In an attempt to address the potential sources of anomalous results seen in the 2000 study, the 2002 project was modified and a new, re-designed BPS test system and approach were developed. This report focuses on the 2002 study with a discussion of the results with respect to data collected in 2000, as well as at other BPS test sites. Results from the 2002 study demonstrate the potential for the BPS technology to improve water clarity and other water quality conditions in the Lower Charles River.
