(:ryptospondium (part 2 of 2) Page 1 of 11 �� -Z3 �� �� snN �ncesc�o Pu6Gc Utilities Commisaion Cryptosporidium (part 2 of 2) In 1997, the SFPUC staff were part of a nationwide effort coordinated by the American Water Works Association Research Foundation (AWWARF) entitled Critical Evaluations of Cryptosporidium Research and Research needs. The document outlines a long-term research strategy for the water industry. Individual agency activities as of December 1992 are summarized in Appendix A. References to Cryptosporidium concentrations are difficult to interpret due to differences in method and sample volume. San Francisco Public Utilities Commission (SFPUC) Activities The SFPUC has been aggressively pursuing the issue of Cryptospo�idium in the following manner: ■ Monitorina - Preliminary monitoring for Giardia and Cryptosporidium was conducted in 1990. This has been followed by an intensive 12-month monitoring program for all sources, both treatment plants, and two distribution system reservoirs. The program has been completed, although some monitoring continues. ■ Consultations - A number of ineetings have taken place with DHS staff regarding Cryptosporidium. In July 1992, the SFPUC met with health officials from the four Bay Area counties served by the SFPUC to discuss the significance of waterborne Cryptosporidium. In November 1992, SFPUC staff met with four water utilities to discuss their respective programs on Cryptosporidium (Appendix B). In January 1993, the SFPUC convened a workshop with regulatory authorities (i.e., DHS and EPA), public health officials, researchers and medical experts to discuss the incidence of cryptosporidiosis, its relative public health significance, current research, and potential studies to address the major uncertainties (Appendix C). A Bay Area workshop was held in June 1995 to evaluate a disease surveillance program and to discuss risk communication issues (Appendix D). The SFPUC conducted stakeholder interviews to assess public concern and attitudes towards costs of various treatment alternatives in 1995. Findings of these interviews indicated a low public awareness of Cryptosporidium, though high concern among water treatment and public health professionals. In addition, San Francisco supervisor Carole Migden formed a 17 member multi-disciplinary Cryptosporidium task force for the purpose of developing guidelines for public notification of immunocompromised individuals and the general public. Due to a concurrent risk communication effort by a consortium of water utilities and DHS, this committee never completed its work. In late-1996, the SFPUC began regular strategy sessions with the major unfiltered sources in the U.S. (i.e., Boston, New York City, http:/lsfwater.org/printContent.cfin/C_ID/445/ 10/19/2004 �. _.. _ �.. _
