All samples will be submitted to the contracted laboratory for analysis. <br /> The field technician will collect a minimum of five rinse blanks per quarter to <br /> submit to our contracted laboratory for analysis. <br /> 6. Sample Types <br /> 6.1. Duplicate Samples <br /> Duplicate samples are two or more samples collected at the same time from the <br /> same location and are used to check the analyzing laboratory's accuracy. Sample <br /> frequency for duplicate samples is described in the Section 5.1. <br /> 6.2. Rinse Blanks <br /> A rinse blank is a sample of analyte free waterpoured over or through a <br /> • p yt g <br /> decontaminated field sampling equipment prior to the collection of environmental <br /> samples. Rinse blanks should be completed periodically to confirm that field <br /> sampling equipment is decontaminated. The field sampling technician will collect <br /> a minimum of five rinse blanks per quarter for laboratory analysis. <br /> 7. Documentation and Records <br /> Field data is at least as important as the analytical data received from the outside <br /> laboratory. Because field data includes an evaluation of the specific instantaneous <br /> conditions at the site, this information cannot be reproduced by a later trip to the <br /> site. <br /> The field data is often the first indication that there may be a concern with water <br /> quality at a given location. Therefore it is critical that any conditions observed are <br /> recorded in the field book. <br /> 7.1. Field Data <br /> Field data recorded at each surface, and groundwater monitoring location shall be <br /> recorded on the applicable field sampling log (surface or groundwater) and will <br /> also be entered into the electronic data collection section for the Monitor Pro 5 <br /> Department THIS DOCUMENT IS UNCONTROLLED IN HARD COPY FORMAT Doc Id: <br /> SE?K Date of This Issue--/--/-- Date of Next Review:--/--/-- Page 18 of 73 <br />
