Federal Updates
- USEPA publishes guidance for states to implement the Ground Water Rule; the complete draft Guidance document (PDF file, 1 MB) and appendices (PDF file, 1.3 MB)
Commentary: As much as any other USEPA drinking water rule, the GWR provides latitude for state primacy agencies in the implementation of the rule. While this guidance document is directed primarily at letting the states know what the limits of that latitude are, water utilities will want to stay tuned to find out what to expect.
- USEPA's semiannual regulatory agenda (Federal Register, December 10)
Commentary: After wading through a wealth of "bureaucratese," it appears that the bottom line for drinking water is that the date for "final action" on a radon rule is May, 2009, and the operative dates for the TCR/DS rule include a rulemaking notice in April, 2010, and a final rule in October, 2012.
State Updates
Water Treatment
- Portland, OR, will likely pursue variance from EPA's treatment requirements (Oregonian, December 10)
- Ithaca, NY, grapples with big decision: Rebuild an aging plant to treat a suspect source or rely on joint-agency facility (Ithaca Journal, December 8); the unique multi-agency Bolton Point water treatment plant and system
Commentary: Emerging contaminants may impact the city's decision on which source to pursue. The newspaper provides a wealth of detail with great photos, but we hope they've got it wrong about chlorate being an intended product of the chlorine-dioxide treatment process used. It is understandable why everyone just calls it Bolton Point, as the agency's full name is a mouthful (Southern Cayuga Lake Intermunicipal Water Commission).
- NASA includes university's drinking water treatment technology in its 2007 technology review (NASA Tech Briefs); the iron-based filtration process holds promise (University of Delaware, December 7)
- Florida city/county proposal for treating distant river's water meets objections (Ocala Star Banner, December 11)
Commentary: The project faces difficult barriers, including the high cost of moving water 173 miles and treating it, and serious concerns about negative impacts on the river. If the internet information about the Ocklawaha (a Muscogee-Creek word for "muddy") is close to correct, it illustrates the extremes needed to get something "wet" to the water consumers.
- Ohio city's new two-stage softening/filtration water treatment plant is on-line and "the coffee tastes better; the ice is clearer"

Chromium
- Hexavalent chromium blamed for health problems from Greek river (London Guardian, December 5)
Commentary: Apparently the river discussed is used as a source of drinking water. The article describes the river as follows: "A putrid stench rises from the river, whose waters run from red to black and ripple with bubbling sludge."
