 Even with the data processed in this form, the results

of a few sample runs still did not indicate a linear

relationship between log of concentration and time. This

poor correlation is indicated by the low correlation

coefficients (R2) in Tables 5-14 and 5-15. Both raw and

normalized data sets and some curves plotted with raw data

are presented in Appendix C.
