Filtered available phosphate by flow injection analysis (FIA) employing the molybdenum blue method provides a rapid analysis that fits easily into a general chemistry lab class time frame. In the Division of Natural Sciences at Salt Lake Community College cross discipline undergraduate research projects are encouraged. In this case, an Environmental Geology class has a field project taking samples and measurements for a range of chemical species and physical parameters of alpine creeks in the Wasatch Mountains. There was a need for determining phosphate concentrations in the ppb range. Also, the Chemistry department is in the process of updating the labs to make more use of the instrumentation recently made available. Therefore, the development of a FIA colorimetric method for phosphate determination was advantageous for both departments. The FIA method and results for the creek samples are presented in this work and thus available to other institutions for possible implementation in their programs.
