Details: SUMMARY: LT-2 EWSTR Crypto Monitoring Assistance DETAILS: System requested assistance to help determine decision making for compliance LT-2 ESWTR regarding Crypto. E Coli sampling exceeded the 10 colonies/100 ml trigger and crypto monitoring is required beginning 4/2010. I talked with John about the Crypto testing procedures, sampling schedule, costs involved, bin classification and microbial toolbox information so he had sufficient information to present to the water board. We also discussed providing a 5.5 log removal modifications to the WTP in order to meet the rule requirements. He will present information to the board and notify DWP of the decision in early 2010. ACTION NEEDED: None at this time.
