Checklist for Submitting Grandfathered Cryptosporidium Data
~	Cover letter. Does the data package include a signed cover letter certifying that the data
represent the plant's current source water and that all source water Cryptosporidium
monitoring results collected during the LT2 rule monitoring period are included in the
package?
~	Sampling schedule. Does the data package include a sample collection schedule established
before beginning monitoring?
~	Additional documentation. Have you included any additional documentation required
regarding resampling, the use of presedimentation, and/or off stream storage during routine
plant operation?
~	List of samples. Does the data package include a list of the field and matrix spike (MS)
samples submitted in the data package, identified by sample ID and collection date?
~	Number of field samples. Does the data package include at least 24 field samples collected
over 2 years?
~	Completeness of results. Are all applicable field sample results from the monitoring period
included?
~	MS sample results. Is the number of MS results submitted equivalent to at least 5% of the
number of field sample results?
~	Sample data. Are the minimum data elements (specified in Section 7.2.1 of the LT2 rule
source water monitoring guidance manaual) provided for each field and MS sample?
~	Sample volumes. Are the volume analyzed for all field samples at least 10 L? For samples in
which less than 10 L was examined, were at least 2 mL of packed pellet volume analyzed or
did two filters clog?
~	Quality control (QC) certification. Does the data package include a letter from the
laboratory certifying that all method-required QC requirements were acceptable for every
field and MS sample submitted with the package?
~	Detailed quality control information. If bench sheets and report forms with QC information
are included, rather than a laboratory letter, are the following requirements met?
~	Sample temperature requirements. Was the temperature of all monitoring samples
between 0°C and 8°C upon receipt?
~	Ongoing precision and recovery (OPR) recovery. Do All OPR sample results meet QC
acceptance criteria of the method version used for the analysis?
~	OPR frequency. Is an acceptable OPR sample associated with every field sample?
~	Method blank results. Are all method blank sample results acceptable?
~	Method blank frequency. Is an acceptable method blank sample associated with every
field sample?
~	Spike levels. Were spike levels of 500 oocysts or less used for all OPR and MS samples?
~	Holding times. Were all holding times met for all field and QC samples for composite
samples, holding times start when collection of the first sample begins?
~	Staining control frequency. Are positive and negative staining controls associated with
all field and QC samples?
~	Staining control results. Were positive and negative staining controls acceptable for all
field and QC samples?
