In 1977, approximately one ton (one truckload) of various pesticides reportedly were buried at SWMU No. 3. The precise location of the burial trench is not available from records. The suspected burial trench lies in the vicinity of a 66-in. diameter water main which supplies the city of San Juan with potable drinking water. There is concern over the possibility of pesticide- contaminated groundwater infiltrating through the line's seals when the line is depressurized during periodic maintenance. Investigations at this site have been ongoing since 1983 and include groundwater monitoring, trenching, and soil sampling. The geophysical investigation presented in this report was designed to detect anomalous conditions indicative of a possible burial trench. The geophysical program included electromagnetic induction and magnetic survey methods. The results of the various surveys were integrated and numerous anomalous areas were interpreted. Anomalies warranting further investigation were presented along with a priority ranking.
