I was a member of the Turbidimeter Team. This team worked to create a low cost turbidimeter prototype to be used by communities in Honduras. At the end of the summer we were able to ship ten turbidimeters to HondorusHonduras; the design only cost about $4. This design consisted of a plastic stick about 60 cm long to which was attached a LED light and a HDPE block with a simple design stuck to top of it. This design could read NTU values down to 15 NTU; in the future hopefully a turbidimeter that can read NTU values down to 5 NTU or lower can be created.
