Our Experiments and Proposal to Siemens

We did 2 experiments:

1. To compare wet cleaning's quality of cleaning to drycleaning.
-We stained swatches of fabric and gave them to a wet cleaner and a dry cleaner.
-Then we compared the results.
2. To compare the effluence of a wet cleaning machine and a domestic washer
-We took the effluence and compared it using an Ion Cromatograph, Total Suspended Solids,and a Gas Chomatograph test

We also presented at the Lexington Public Library and to the Selectmen.
