This semester I am a member of the Turbidimeter Team. Our goal is to design a low budget (under $20), accurate turbidimeter. These turbidimeters will be provided to candidate communities to determine the source water turbidity range and hence the type of water treatment required. My teammates and I have created a prototype. The prototype consists of an LED light covered with a secchi disk design which is lowered into a tube of turbid water. Currently my teammates and I are finding the relationship between turbidity and the distance in which the secchi disk design is indistinguishable. A relationship between the depth that the design was no longer visible and turbidity was found and a scale was made accordingly.

This semester I am a member of the Turbidimeter/Inlet Manifold team. Our goals for this semester include making the current turbidimeter design more accurate and able to measure lower turbidity (1-5 NTU), create an AutoCAD drawing of our design, write a journal article to submit to the Journal of Environmental Engineering describing the turbidimeter design and use , and to design a method to fabricate then new inlet manifold by late October.
