a$)$ Plot P$.$S$.$D$.$ for "Bio$7$ Failed" and "Bio$7$ Working"

b$)$ Quantify $\%$ gravel, $\%$ sand, $\%$ fines for "Bio$7$ Failed" and "Bio$7$ Working"

c$)$ Classify "Bio$7$ Failed" according to USCS.

d$)$ Classify "Bio$7$ working" according to USCS.

e$)$ Compare the classification of the working versus the failed gardens. What factors are potentially impairing the ability of the failed rain gardens?
