Amendments to the Safe Drinking Water Act (SDWA) of 1996 require the US Environmental Protection Agency (USEPA) to develop new rules to control Cryptosporidium and chemical byproducts of the disinfection process. This may force operators to evaluate whether their current practices will still be technologically sound when the new rules take effect. One such process under scrutiny is slow sand filtration. This article describes what slow sand filtration is, and how it is viewed by operators, state regulators, and the USEPA.
