Hey EWB, Here is a link to the report on the grey water testing in the slow sand filter that Hanna and I did for our course design project if you're interested in the results. Let us know if you have any questions. Sorry I forgot to send this out sooner as I know some of you are working on some stuff over break and wanted this report. https://drive.google.com/file/d/0B5VxYaZt33zFOHV3REJGY1prSzA/view?usp=sharing Hope you all are having a great break!!!!! Your Co-pres, Baxter
