Reclamation will hold two more public meetings in California in early June. On <br />June 10,2003, the meeting will be held in the San Diego area; and on June 11"', the meeting will be held <br />in downtown Los Angeles at the Headquarters offices of the Metropolitan Water District of Southern <br />California. Included in the Board folder is a copy ofthe introductory remarks made by the Board staff <br />which summarized California's historical use of Colorado River water; discussed California's Draft <br />Colorado River Water Use Plan; current hydrologic conditions in the Colorado River System; and <br />support for Reclamation's efforts to manage the available water supply better, <br /> <br />Board staff attended Reclamation's "Era of Limits" public outreach meeting, May 21,2003, in <br />Coachella, California, At the meeting, Reclamation staff provided an overview of Basinwide hydrology <br />and future hydrologic forecasts, operations and reservoir system management, Article V Decree <br />accounting requirements, Yuma Area operations, salinity management, and Mexican Treaty obligations. <br />With Lower Basin demand at, or very near, the full 7.5 million acre-feet per year apportionment, <br />Reclamation emphasized that the System must be managed more efficiently in the future, <br /> <br />The meeting in Coachella was well attended, with approximately 25-30 in the audience, <br />Reclamation invited the audience to raise questions as they were identified during the presentations, <br />There was significant concern expressed by representatives of the CVWD associated with impending <br />the Part 4 I 7 process and determinations in the Imperial Irrigation District, as well as the impact to <br />CVWD related to the loss of nearly 108,000 acre-feet of Colorado River mainstream water associated <br />with the U.S. District Court's decision in lID vs. United States earlier this Spring. Local residents in <br />the Coachella region were concerned that other California Colorado River water users were continuing <br />to utilize significant quantities of mainstream water while those in the Palm Springs and Coachella <br />regions were forced to cut back. <br /> <br />Perchlorate-State of Scientific Know/edge <br /> <br />At last months Board meeting, there was a discussion regarding detectable levels of perchlorate <br />in Colorado River water and the impact it has or may have on the environment. In response to that <br />exchange, staff has prepared a report, which has been included in the Board folder. <br /> <br />The objective ofthis report is to provide an overview of the current information on perchlorate <br />)" including; its characteristics, sources of perchlorate contamination; health effects of perchlorate in <br />drinking water and food; standards for perchlorate and regulatory status; perchlorate contamination in <br />California; and treatment options. It is an informational document prepared for members of the <br />Colorado River Board of California. <br /> <br />Perchlorate has been found in drinking water throughout the southwestern United States. <br />Ammonium perchlorate is manufactured for use as the primary component in solid propellant for <br />rockets, missiles, and fireworks. In the body, perchlorate interferes with the uptake of iodine by the <br />thyroid gland, causing disruption of thyroid hormone production. <br /> <br />5 <br />
