Abstract

The purpose for this experiment was to compare relative concentrations of the herbicide atrazine in soil and ground water samples. Atrazine is commonly found in groundwater and is known to be toxic to aquatic life with long lasting effects. This experiment aims to identify whether or not atrazine is present in the groundwater as well as to examine how long atrazine can persist in soil. Previous studies have shown atrazine and other related herbicides persisting with little to no degradation for up to 16 weeks. Soil and groundwater samples were obtained from a farm where atrazine is used seasonally to treat a field before and after corn has been planted. Weekly groundwater samples were taken and representative samples were taken from his field. To analyze water samples, solid phase extraction and gas chromatography-mass spectrometry (GC-MS) were used. Soil extracts were first filtered and then analyzed with GC-MS.
