B. Follow -up Information Concerning Cryptosporidium in Recycled Water Public Works Services Director Ingram stated that the learning, technology and emphasis on cryptosporidium monitoring and testing continues to be related to drinking water which would not apply to recycled water in Redwood City. Public Comment: Dave Valkanaar, retired Foster City Engineer and District Engineer, commended the design of the facility plan. He urged for consideration that there would be puddling of recycled water with likely lapping up by dogs and cats with possible passage of cryptosporidium bacteria onto children in the household. Although not a requirement of Title 22 for recycled water, he urged consideration of testing the recycled water for cryptosporidium and giardia and a plan to deal with it if detected. Chet Yee, former Recycled Water Committee Member, agreed with the previous speaker that cryptosporidium is something to be sensitized to. He stated that 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 Council 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.
