Surface Water <br />Field notes are kept of all work in an organized manner to document field procedures, and the <br />data parameters recorded are site flow/discharge, field parameters (temperature, pH, <br />conductivity, and dissolved oxygen), remarks, sample collected and lab name, equipment list, <br />and sampler's name. <br />Sample collection consists of water grab samples. A pitcher is triple rinsed before the grab <br />sample is collected. Raw sample bottles are filled directly from the pitcher. Filtered sample <br />bottles are filled by filtering water which is collected from the pitcher or a gallon size triple <br />rinsed plastic bottle. Some sample bottles require filtration to fill the bottles. A peristaltic pump <br />is used to slowly pump the water through a 0.45µm pore size disposable filter. The pump tubing <br />is rinsed with distilled water before and after use. <br />Groundwater <br />Field notes are kept of all work in an organized manner to document field procedures, and the <br />data parameters recorded are well identification, date and time, well casing, diameter, casing <br />material, total depth, water depth, bore volumes, pumping depth, pumping time, flow rate - <br />purging (when possible) sampling, pH, conductivity, temperature, samples collected, and <br />equipment list. Water level measurements are static water level measurements that are made at <br />each well from a known reference point at the top of the well casing. The level is measured to <br />the hundredth of a foot. Well purging of WW1 1, WW-EF-01 and TH-A6 wells are done with <br />dedicated pumps at a flow rate determined by the pump. MW-12 well is purged using a portable <br />Redi Flow II pump. Purging procedures include pumping stagnant water from each well. Well <br />purging is considered finished when three bore volumes are pumped while monitoring water <br />temperature, pH, and conductivity. These parameters should be consistent before sampling. <br />Sample collection is done after well purging. Raw sample bottles are filled directly from the <br />pump discharge tube. Filtered sample bottles are filtered from a triple rinsed plastic bottle. Some <br />sample bottles require filtration to fill the bottles. A peristaltic pump is used to slowly pump the <br />water through a 0.45µm pore size disposable filter. The pump tubing is rinsed with distilled <br />water before and after use. (The MW-12 filtration is done at the pump discharge tubing because <br />of the variable flow rate of the Redi Flow II pump.) <br />Sample Sets <br />Sample sets are ordered from the laboratory. They arrive in a cooler with the required paper <br />work and preservatives. Instructions are included for filling bottles, labeling, packing and chain <br />of custody. Labels are filled out for each bottle as to sample I.D., date, time, analysis, <br />preservative and filtration. Sample bottles are labeled and filled in the field according to <br />laboratory instructions. The bottles are cleaned, dried and placed in a cooler with ice. The <br />current sample size is one site per cooler. At the end of each day's sampling a Chain of Custody <br />(COC) document, and over night shipping papers are filled out. Coolers are repacked with all <br />glass bottles bubble wrapped, new ice containers and additional packaging are added so there can <br />be no movement of bottles in the cooler. The shipping papers and COC are attached to the <br />outside of the cooler, and a copy of the COC placed inside the cooler. Coolers are sealed with <br />wrapping tape and tamper proof seals then delivered to Federal Express for overnight shipping.
