Specifications include, but are not limited to: Multiple composite samples will be collected at the base of each quadrant that is excavated. Typically one sample will be collected from each quadrant (defined below) that is excavated. Additional samples will be collected from excavated gardens and play areas, if present. A site sketch will be prepared, which will show all structures, quadrants sampled and major features, such as play areas, gardens and paved areas. One composite sample, comprised of five roughly equal aliquots, will be collected from each excavated quadrant, within the top 6 inches of the surface. Composite samples will also be collected from excavated ROW, play areas, garden areas and drip zones. The following procedure will be used when collecting and analyzing surface soil samples: 1. Document in the logbook and on field sheet the locations of the quadrants and other pertinent information, including sampling Team Members, Date, Time, and Weather conditions. 2. Don a clean pair of nitrile gloves (non-latex, powder free). 3. Using a clean, stainless steel hand trowel or spoon, collect five aliquots from the top 6 inches of soil from widely distributed locations within each quadrant. Collect approximately 50 grams of soil from each aliquot location. Place the aliquot soil samples in a Ziploc® bag labeled with the sample # and quadrant designation. Each soil sample bag will then be placed in a larger bag containing the date, SAID #, property address/ location and total # of samples. Samples are then carefully placed in a sealable container to be transported from the property site to the soil remediation contractor field office. 4. Grass and rocks will be removed from the composite sample, which will be thoroughly mixed. Excess soil and debris is kept in a secured storage container, to be removed later by a soil remediation contractor. 5. Samples will be air-dried; however, lab technicians may dry the samples under a heat lamp or a toaster oven for 5 minutes at 200 degrees Fahrenheit, if the soil is to moist for sieving.
