We hope that 2008 brings you lots of good news... starting with this issue! If not good, at least
interesting.
The
candidates in New Hampshire are doing lots
of talking but are they
talking about MTBE?
When are boil water advisories advisable? Cost
of arsenic treatment facilities keeps going up,
but some New Mexico systems
get another year to
comply. Reusable bottles: It's more about
the bottles than the water
in them!
Idaho's
latest Drinking Water
Newsletter (PDF file, 1.09 MB) Commentary: Idaho lists the "do's and don'ts" for Intermittent Chlorine Disinfection–when it is appropriate and when it is not! Plus info on Biofilm. (Did you know that the plaque on your teeth is an example of
biofilm? Yuck!)
Ohio
has
revised its TCR and
Public Notification Rule (PDF file,

has a "...new
provision requiring public water systems that
experience physical or
operational disruptions with a
significant loss in pressure and
also have obtained
bacteriological samples positive
for E. coli or fecal coliform to
issue a Tier I public notice." This
common-sense approach seems to run counter to
what has been noted recently
in news reports from other states–that is,
issuing BWAs whenever there is any
disruption with loss in pressure irrespective
of sampling data. Ohio
distinguishes between main
breaks and other
"operational"
disruptions in the following new technical
guidance document: Evaluating
and responding to water
distribution systems and
subsystems that have
depressurized (PDF file, 31 K)
Florida
agency may ask county to speed
up ground water treatment plant
construction (Palm Beach
Post, January 8)
Commentary: The move to accelerate getting a new IX plant online to treat ground water is understandable in light of deterioration in the quality of Lake Okeechobee as its levels drop: "Water from the lake is harder to treat when levels are low because there is a higher concentration of mix of sugar-plantation runoff, cow manure, algae, bottom muck and drainage from marshes upstream."
