This week's NEWS
........is really two weeks of news, most of which has been totally and appropriately overshadowed by far more important news. Help is available for water utilities on protecting water infrastructure. With the reports from all three of their special advisory groups submitted, some insiders suggest that USEPA will propose a "lower" Arsenic MCL! Delaware already adopted 10 ppb and California rule-makers may have to march to their own drumbeat. From Arvin to Albuquerque & Bad Axe to Brown City, arsenic cost worries abound. California Legislature passes hexavalent chromium standard mandate despite blue-ribbon panel recommendation to wait. AwwaRF study leads to perchlorate treatment process acceptance. Settlement pours more money into Tahoe MTBE cleanup. And much more............

NAS' National Research Council report says arsenic
risk is higher than reported in 1999

report is available
Arsenic Rule Benefits Review Panel recommends EPA
modify its analysis (pdf

source indicates arsenic standard may be lower than
10 ppb (Boston
Globe, September 11)
Pundits inside and outside of USEPA are suggesting
that the combined effect of the three special
reports submitted to EPA by expert advisory groups
on costs, benefits and health-risks, will be a lower
MCL. As expected,
the major impact will be from the NRC report
concluding that evidence of cancer links are
stronger than reported before and that other health
effects should be considered. The value of benefits
from a lower standard may more than offset smaller
changes that might evolve from a new look at
- Revised health risk suggests lower standard needed (LA Times, September 15)
lowers its arsenic standard to 10 ppb
463, requiring a California standard for arsenic by
2004, goes to Governor
With late amendments giving OEHHA and DHS officials
more time to develop, respectively, the PHG and MCL,
USEPA's final arsenic rule activities will be
available for full California consideration. The
cost-of-compliance equation in California could be
somewhat different than nationally because of (a) the
definition of arsenic-laden residuals as hazardous
waste in California; and (b) the possible complication
of residuals removed also being classified as
radioactive waste due to concurrent removal of low
levels of uranium.
