The cascade continues when utilities try to combat these and other threats by treating drinking water with chemical disinfectants such as chlorine. Treating algal contamination this way gives rise to carcinogenic disin- fection byproducts, whose levels typically spike during the summer months – when algae blooms peak. Com- monly used measures to reduce algal contamination add hundreds of thousands of dollars annually to water utilities’ treatment costs. Algae can also give tap water an unpleasant taste and smell, a recurrent annoyance for agricultural areas and the water utilities that serve them. This report focused on four states in the core of the. | SUB906805-025 Bk JMlh A I NTS Alert Environmental Pollution Control December 15 2005 Volume 05 Number 25 IMPORTANT NOTICE Items cited below are available from the National Technical Information Service NTIS .

DE2005-15011425WEP Price code PC A04 MF A01 Condor County Consulting on behalf of Lawrence Livermore National Laboratory LLNL has performed wet season surveys for listed branchiopods at Site 300 located in eastern Alameda County and western San Joaquin County. LLNL is collecting information for the preparation of an EIS covering ongoing explosives testing and related activities on Site 300. Related activities include maintenance of fire roads and annual control burns of approximately 607 hectares 1500 acres . Control burns typically take place on the northern portion of the site. Because natural branchiopod habitat is sparse on Site 300 it is not surprising that listed branchiopods were not observed during this 2001-2002 wet season survey. Although the site is large a majority of it has topography and geology that precludes the formation of static seasonal pools. Even the relatively gentle topography of the northern half of the site contains few areas where water pools .
