Yesterday, 3/27/2012, the water quality group measured phosphate levels in the water samples taken from all of the creeks by adding reagents to 10 mL of water and using a spectrophotometer to measure phosphate levels. We worked in class for about 1 hour and then again from 7:00 - 8:30 p.m. and were able to finish all of the phosphate levels in the samples. Overall it seems that phosphate levels were found in relatively higher amounts than compared to nitrate levels. We still are needing to test for ammonium levels whihc we will be doing this Friday.
