Listen to this OPB interview with Portland Water Bureau administrator David Shaff this morning. He confirms that the variance announced yesterday can be easily revoked because the state will not attempt to distinguish between types of cryptosporidium. MOST are not infectious to humans yet any detection of any type will count against us. He characterizes the conditions set by the state as "3 strikes and you're out." Yet another reason why we must act quickly to change the LT2 rule now under review by the EPA.
