NOTES:Prepared by: JHG Checked by: KF
Only constituents detected above the PQL in compliance wells during the March 2015 monitoirng event were analyzed.
Prediction limit comparison type is based on the percentage of nondetects and distribution of the dataset (Table 1)
PQL Practical quantitation limit
*Data set does not contain any nondetects
None Required Percentage of nondetects greater than or equal to 50 percent and less than 90 percent or dataset is non-normally distributed
Replace with 1/2 PQL Percentage of nondetects less than 50 percent and the data distribution is normal or lognormal or percentage of nondetects is greater than or equal to 90 percent
(ND)Prediction limit for nonparametric comparison was the PQL for a nondetect
Result exceeds the prediction limit
