Water Quality Analysis from the Department of Earth Sciences

Below are the results for the water quality analysis conducted by BU's Earth Sciences Department. The EPA limits are listed below each compound. Magnesium, Phosphorous, and Calcium are not regulated because they are not necessarily harmful but may cause differences in taste. Magnesium and Calcium are only required by law to be reported by municipal sources if they are above the concentration of 100 parts per billion (highlighted in pink). The highest concentrations in each column are highlighted in green.
