13.1.1 3 SOP'S - ICR manifold, well-slide. Method 1623 13.1.2 1 QAP - describing all laboratory calibrations and quality control practices 13.1.3 1 QAPP - Routine Keypoint Protozoan Monitoring
13.2 QC Per sample 13.2.1 Postive and negative control slides are prepared with each sample to ensure stain performance, and comparative cyst and oocyst appearance. Results are pass/fail.
13.3 Weekly or Biweekly QC (equivalent to “Batch" QC) 13.3.1 Positive and negative spikes are added to carboys of DI water, filtered and taken through the entire ICR analytical procedure to ensure the negative spike remains negative and the positive spike results in recovery. Results are recorded as percent recovery. 13.3.2 Positive and negative spikes are added to carboys of DI water, filtered and taken through the entire Method 1623 analytical procedure to ensure the negative spike remains negative and the positive spike results in recovery. Results are recorded as percent recovery.
13.4 Monthly or Bimonthly QC 13.4.1 Precision of microscopic counts is performed between principle analysts for both cysts and oocysts by replicate counting of the same slides of unknown concentration.
13.5 Quarterly QC 13.5.1 The DEP is registered to electively participate in the EPA PE program for the ICR manifold method and for Method 1623. Samples are delivered quarterly for ongoing precision and recovery.
