On January 19, 2000 the START conducted the third sampling event. Four samples were <br /> taken from the following locations: <br /> RMC Lonestar- Industrial well <br /> Teichert Aggregates - Industrial well <br /> 30010 S. MacArthur-Residential well <br /> 8930 Palmquist - Residential well <br /> There were two minor differences between the sample locations for this event and the other sampling <br /> events. The well at 30010 S. MacArthur had a water softening system installed on their well. <br /> Because there were no water taps before the water softening system, the samples were collected <br /> downstream of the water softening system. Previous samples had been collected at 8952 Palmquist <br /> however the water supply to 8952 Palmquist is provided by the residential well at 8930 Palmquist, <br /> so samples were taken from an exterior water tap at 8930 Palmquist. <br /> The groundwater samples were submitted to APPL, Inc. Laboratory in Fresno, California for <br /> definitive analysis of the following contaminants of concern: <br />
