Source Water Quality in Haiti: Water quality data from six water sources were collected in Haiti. The E. coli concentrations in the samples ranged from 1.5 Most Probable Number (MPN) of E. coli per 100 mL of the sample to 48.3 MPN of E. coli per 100 mL of sample. The experiments proved that the GOW systems can effectively inactivate these levels of E. coli concentrations. The turbidity measurements ranged from 0.19 NTU to 6.64 NTU. The experiments also proved that the GOW systems can meet the EPA turbidity regulations based on this data. This water was dramatically less turbid than the Wabash River water used for testing. The source water samples were also generally less turbid than the water used for the clogging rate experiments at the effluent contact chamber at the West Lafayette WWTP. Under the time periods studied, the water used in experiments at Purdue University in Spring 2013 were worse than what the GOW filter users would experience in Haiti.
