several recent clinical papers have shown that animals having lapped up recycled or pooled water have been shown to have passed the cryptosporidium to infants and children in daycare nursery schools. He further stated his hope that should better methods for testing for cryptosporidium be available that the City will be prepared to implement the testing. Bob Parkhurst asked Jim Bewley of SBSA to explain the holding tank and whether a flow through or batch process will be used. Jim Bewley, SBSA Manager, stated that the treatment process in the filtration is a continuous flow through. The chlorine contact tank is a continuous flow through while producing recycled water and the storage tanks would be used to match the distribution rates since most of the water will go to irrigation and most of that occurs in the middle of the night. The highest outflow of product water will be in the middle of the night, but that is when the treatment plant flow is the lowest. Christina Lai, founder of Safe Water Coalition, stated that for over a year she has represented a large number of supporters on the issue of cryptosporidium found in recycled water and the hope is that Council did study Dr. Rose's published paper carefully and will follow her recommendations. She further stated the Coalition's disappointment in the staff recommendation because the Coalition would like to see the Council be more proactive by following those states that already have standards in place for testing for cryptosporidium. She stated that since the Gouncil will need more time to approve a policy regarding cryptosporidium, to be fair, she asked Public Works staff to delay pursuing any homeowners' associations to sign up for the recycled water program until Council votes on a policy decision. Camille Fischer, a veterinarian and Recycled Water Committee Member, stated her interest in seeing the project go forward in a way that the community can embrace. She stated that cryptosporidium and giardia are two disease causing organisms that can be found in recycled water and are both are removed in similar ways and are similarly resistant to chlorination. She stated that it would be appropriate during the pilot program to measure the level of cryptosporidium present. She further stated that while water is a major way that cryptosporidium is acquired, foods and environmental services could be contaminated and an animal may ingest the one to ten spores necessary to set up an infection. Council asked various questions of staff and Jim Bewley and made comments such as needing to study further to know the amount of cryptosporidium and determine the effects of transmission on animals. Public Works Services Director Ingram stated that the City would continue to gather data as early as possible from the various resources both locally and through the international network of associations. He stated his belief that there would be a reasonable way to perform testing and compile data and it would not CITY COUNCIL AND REDEVELOPMENT AGENCY OCTOBER 25, 2004 JOINT MEETING MINUTES PAGE 7 - r
