Wells in Puerto Rico have experienced elevated nitrate concentrations in recent years. Our group, along with the help of the U.S. Geological Survey, conducted water sampling in eastern Puerto Rico to determine nitrate concentrations in ground and surface water. Sampling in El Yunque, the rain forest, was used to determine natural nitrate concentrations. Samples taken outside of the rain forest were compared to El Yunque to determine how different land usages change nitrate concentrations. We found that none of the areas sampled during our study contained nitrate concentrations over the Environmental Protection Agency's limit of 10 mg/L of nitrate as nitrogen in drinking water. We recommend further sampling.
