This document contains the results of an analysis of iron concentration in several standard and sample solutions. Six standard solutions with known iron concentrations were measured to generate a calibration curve. Five samples of river water collected at locations BMK1 through BMK5 were then analyzed to determine their iron content based on the calibration. A final sample from location BMS1 was also tested. The mean iron concentration and standard deviation were reported for each standard and sample.
