This week's NEWS
E. coli: The long and the short of it. When does public notification become a disservice to the public? It doesn't matter if you call it "reservoir augmentation" or "toilet-to-tap," recycling in San Diego is "arguable." Navajos are in the spotlight when it comes to SDWA primacy and uranium. Consolidation to help with compliance pops up in Illinois (the cornfield pub), in Nevada (arsenic hook-up) and, sort of, in Iowa (a perchlorate
response plan).

Federal Update
- USEPA divides up funds for surveillance of public water systems on Indian tribal lands for 2008
Commentary: In 1986, the SDWA was amended to allow U.S. Indian tribes to assume primacy for water systems on their lands but only the Navajo Nation has done so. The oversight funding is distributed to the 10 EPA Regions with 70% of the funding going to 3 regions in the west. Funding is allocated based on Indian population, the amount of tribal land, and the number of public water systems.

Notification
- Connecticut town tries to calm residents' fears after public notice of positive total coliform samples from "a bad sampling tap" (Middletown Press, October 29)
Commentary: Maybe the FACA group working on the TCR will come up with a solution to this age-old problem: Water system uses household spigot for a regular sample. Sample is total-coliform positive. Follow-up samples – upstream and downstream – are negative, but the "bad tap" is still positive. What does that mean? Does it warrant the cost, effort, and confusion associated with a public notice? (This is not an endorsement of the tendency to quickly point the finger at the "faucet!" Sample site selection and preparation must not be ignored until after a problem occurs.)
Arsenic
Uranium
- Navajos get congressional commitment re: uranium contamination (Gallup Independent, October 25)
Commentary: It would not be surprising if the tribal representatives left the House of Representatives hearing shaking their heads and saying, "I think we've heard these promises before!" Hidden in the obviously staged drama (including bringing radioactive dirt into the Capital) was the Chairman's outrage that anyone would ever consider "blending" as a solution to a contaminant in drinking water. Maybe he should read his home state (California)'s SDWA rules that specifically include blending in the definition of treatment.
