FEATURE ARTICLESAssessing Escherichia coli removal in the schmutzdecke of slow-rate biofiltersMichael Unger and M. Robin Collins Water suppliers can use the findings in this article to improve the performance of existing biofilters by adjusting operations in ways that increase both biofilm growth and activity and protistan activity in the schmutzdecke. Arsenic removal using oxidative media and nanofiltration Kenneth W. Moore, Peter M. Huck, and Steve Siverns Membranes are a promising technology for arsenic treatment because of their simple operation and minimal chemical requirements compared with other technologies. Microfiltration and ultrafiltration membranes for drinking water AWWA Subcommittee on Periodical Publications of the Membrane Process Committee Because the use of microfiltration (MF) and ultrafiltration (UF) in potable water treatment applications has expanded rapidly—both in terms of capacity and number of installations—a comprehensive MF/UF resource for the water treatment industry has become imperative. Evaluating surrogates for Cryptosporidium removal in point-of-use systems Nur Muhammad, Rajib Sinha, E. Radha Krishnan, Haishan Piao, Craig L. Patterson, Joseph Cotruvo, Scott L. Cumberland, Vincent P. Nero, and Carol Delandra This study evaluated the use of surrogates for measuring the microbial treatment performance of two point-of-use devices incorporating filtration with electrostatic charge interaction mechanisms. Secondary effects of implementing arsenic removal treatment—focus on corrosion and microbial regrowth Marc Edwards and Jeffrey L. Parks A new protocol is proposed for detecting the limiting nutrient to microbial growth in drinking water to assist utilities in making treatment option decisions that won't trigger bacterial growth in the distribution system. Incidence and Costs of Home Plumbing Corrosion Ewa J. Kleczyk and Darrell J. Bosch Information on factors associated with pinhole leak incidence and cost can help water utility managers formulate policies and programs to reduce pinhole leak occurrences, thus mitigating the negative financial and emotional effects of corrosion on individual households.
