Soil Sampling. To further assess soil impacts at the facility, H&H proposes to advance soil borings in the following locations: • Four borings will be advanced in the area of floor drains in the portions of the second floor former chemical storage and mix areas that are located over soil (i.e., not located above the basement). The approximate locations of these borings are indicated in Figure 2. • Three soil borings will be advanced in the basement area where the highest levels of silver have been previously detected. One soil boring will be advanced in the area of previous borings 14A, one will be advanced near previous boring Office B, and one will be advanced near previous boring 1B. • One soil boring will be advanced near the sump in the southwestern corner of the basement area where no previous soil sampling has been performed. An attempt will be made to advance a soil boring in the area of the sump within the basement. However, if a boring cannot be advanced within the basement, a sample will be collected just outside the building using a hand auger. The locations of the initial and alternate borings are indicated in Figure 3. • One soil boring will be advanced in the location of the former wastewater USTs in the southeastern portion of the site. The location of this boring is indicated in Figure 1. The borings will be advanced with a direct push technology (DPT) rig or stainless steel hand auger depending upon access constraints. Except for the boring in the area of the wastewater UST, the borings will be advanced to depths of approximately 15 ft, which approximates the depths of the previous borings conducted by Terracon. The soil boring in the area of the former wastewater UST will be advanced to a depth of approximately 20 ft because of the depth of the former tankhold in this area. It is anticipated that one soil sample will be collected from each boring for laboratory analysis, although two soil samples may be collected from some borings depending upon field observations. It is anticipated that 10 to 15 soil samples will be submitted for laboratory analysis from potential areas of concern. The depths of the soil samples submitted for analysis will be based upon field screening with a photoionization detector, and detected odors and staining. The soil samples will be analyzed for volatile organic compounds (VOCs) by EPA Method 8260, and the hazardous substance list (HSL) metals (antimony, arsenic, beryllium, cadmium, chromium, copper, lead, manganese, mercury,...
Soil Sampling. Grower may request SSI to perform soil sampling of Grower’s fields. Such soil sampling will be performed by SSI to the extent feasible, and the cost of such soil sampling will be deducted from the first payment for sugarbeets to be made to Grower under this Agreement. Grower hereby authorizes SSI to make such deduction. Federal ID No. Agreement No. Date: , 2007 XXXXXX SUGARS INCORPORATED (“SSI”) and ”Grower”), [a. corporation, a partnership, an individual]*, whose address is , State of , hereby agree as follows:
Soil Sampling. Soil samples will be screened utilizing a properly calibrated and maintained PID as indicated in Section 3.4. Using that data and other field observations described below, selected soil samples will be placed in appropriate containers for laboratory analysis. All soil samples will be analyzed for the full list of volatile organic compounds(VOCs) by Method 8260+ which necessitates sample collection via methanol preservation. For that method, a quantity of soil will be placed in a clean syringe, weighed and adjusted to 10 grams, and then placed in a laboratory supplied sample vial containing 10 ml of methanol. A second vial of soil or a sealed syringe of soil will be submitted with each methanol preserved sample for dry weight determination. For the purposes of IDW disposal, one soil sample from a location with observable petroleum impact will also be placed in a four ounce jar for TCLP analysis for lead. As specified in the RFP, the protocol for selecting soil samples for laboratory analysis from individual borings will be based upon the following system (1 the highest priority and 7 the lowest priority):
1. any sample with visible staining or sheen 2. soil sample with PID reading over 1000 ppm 3. soil sample with PID between 500 ppm and 999 ppm 4. soil sample with PID between 100 ppm and 499 ppm 5. soil sample with PID 1 ppm to 99 ppm 6. soil sample just above the water table 7. soil sample at terminus of boring if no water is encountered Following collection and proper preservation, the sample container will be labeled as to sample location and depth, logged onto appropriate chain of custody forms, and placed on ice. Samples will be maintained on ice or in refrigerated cooling until delivered to the DEQ laboratory via overnight shipment or hand delivery. All other samples collected during the screening process, but not submitted to the laboratory, will be properly disposed with other IDW as described in Section 3.7 below.
Soil Sampling. Sub-Slab Vapor Sampling
Soil Sampling. Stantec will subcontract with an Oregon-licensed driller to facilitate borehole advancement for the collection of soil samples to address the objectives indicated in Section 2.1. Soil sampling procedures will be performed consistent with QAPP SOP-02 as summarized below: • Retrieve the disposable acetate sleeve from the direct-push system and cautiously slice the sleeve open with a clean utility knife or sleeve knife so as not to disturb the soil; • First collect soil sample(s) for volatile COCs (VOCs and gasoline-range hydrocarbons) using a disposable, small-diameter core sampler (i.e., EnCore®) placing a minimum of a 5-gram sample into a 40-milliliter volatile organic analysis vial; and • Place the remainder of the soil planned for analysis into appropriate sample containers. A new pair of disposable Nitrile gloves must be donned for the collection of each soil sample. Soil samples will be tested for the COCs listed in Table 1.
Soil Sampling. 5.4.1.1 Collection of soil samples is proposed at depths of 0.5, 1.5, 3.0 and 6.0m below ground level (mbgl) using inspection pits (0.5 and 1.5mbgl) and boreholes (3.0 to 6.0mbgl). Borehole sampling should be undertaken by means of dry rotary drilling method (without the use of flushing medium to prevent cross-contamination during sampling). The on-site Land Contamination Specialist will decide on the appropriate depths of sampling at each point according to the actual site conditions.
5.4.1.2 An undisturbed U100 sample should be collected from each sampling depth except at the depths of 0.5 and 1.5mbgl where inspection pit should be employed for the collection of disturbed samples. The disturbed samples should be placed in pre-cleaned glass sample jars. The jars should be covered with laboratory solvent washed aluminium foils and lids. Each jar should be labelled properly and details of the sampling locations and other pertinent data should also be recorded. All samples should be stored in icebox between 2oC – 4oC while in the field or in transit and a chain-of-custody form for samples delivery should be completed after samples collection.
Soil Sampling. The number and type of samples for chemical analysis is specified in the Site Specific Section of the Scope of Services. The sampling procedures and analytical methods are specified in the Site Specific Section of the Scope of Services. Sampling procedures shall meet all requirements outlined in the most recent version of EPA guidance (QA/G-5S, December 2002). Sampling procedures, equipment, and methods shall be addressed in the site- specific UFP-QAPP to ensure Data Quality Objectives are established and met. The UFP-QAPP shall be submitted for review and approval by the COR and appropriate regulatory agencies. Sampling for chemical analysis shall be performed using a stainless steel split-spoon sampler. Alternate sampling methods may be proposed for approval by the COR in the Contractor work plans. Soil grab samples for volatile organic compounds (VOCs) or semi-volatile compounds (SVOCs) analyses shall be obtained by sub- sampling the material retrieved in the split spoon. The portion of the split-spoon sample that represents slough shall not be sub- sampled. Sub-sampling shall be done immediately upon opening the split spoon and shall be done as soon as possible once the split-spoon sample is taken from the boring. When collecting samples with a hand auger, the VOC and SVOC sub- samples shall be collected immediately upon retrieval of the sample at the surface. The Contractor is responsible to recover adequate soil volume for all analytical requirements. If the sample volume of the first sample is not adequate, another sample shall be attempted from immediately below the previous sample or from the same depth in a boring drilled immediately adjacent to the boring in which the sample failed. This shall be done at no additional cost to the Government. The Contractor shall include in the Contractor work plans methods to be used to recover additional samples that are consistent with the project data quality objectives. Shallow soil samples for chemical analysis may be obtained with a stainless steel hand auger or a similar device if approved by the COR in the Contractor work plans. Homogenizing (mixing) of soil samples shall be performed in a stainless steel bowl using stainless steel stirring devices that have been decontaminated prior to each homogenizing procedure. Samples for VOCs or SVOCs shall not be homogenized unless specified in the Site Specific Section of the Scope of Services. Sampling equipment, sampling methods, and decontamination procedures ...
Soil Sampling. Soil sampling shall be conducted and analyzed at Operator’s expense in accordance with a plan to be developed and approved by the City and Operator before any new Operations commence. The soil sampling plan will be used to establish baseline soil conditions and monitor soil conditions during the term of this Agreement.
Soil Sampling. As summarized on Table 1, data from samples collected during the 2008 Canyon Creek Trestle soil sampling activities detected the metals arsenic, cadmium, chromium, lead, and silver in near surface soils at concentrations greater than both conservative risk-screening levels and concentrations deemed typical (e.g., DEQ default levels) of naturally-occurring background for the region. Of these metals, chromium and lead were detected above these levels in a number of samples and over the largest areal extent. The 2008 Toxicity Characteristic Leaching Procedure (TCLP) data suggests the metal levels detected are not leachable at levels that would constitute a RCRA hazardous waste. The 2008 Canyon Creek soil samples were collected at 3-inch depth intervals at each sampling station, with concentrations attenuating vertically with increased depth, and with the deepest sampling interval of 6 to 9-inches below ground surface. Although significantly attenuated, lead and chromium were detected in soil samples from the 6 to 9-inch depth interval and the furthest lateral locations in certain areas at Canyon Creek greater than conservative risk-screening levels and concentrations deemed typical of naturally-occurring background for the region (Table 1). 1 Lead is plotted as an indicator constituent because it is the metal mostly widely detected above its conservative risk screening values and default background concentration show in Table 1. Oak Grove Hydroelectric Project Trestles For the preceding reasons, additional soil sampling for vertical and lateral delineation of arsenic, cadmium, chromium, lead, and silver in soil is deemed appropriate for the Canyon Creek Trestle area. Because existing data does not suggest significant attenuation between the 0 to 3-inch and the 3 to 6-inch depth intervals at many locations; and because a 3-inch resolution will not likely be relevant for evaluating removal action alternatives, all additional soil sampling at the Canyon Creek, Cripple Creek, and Pint Creek Trestles will be conducted using 6-inch depth intervals for characterization and delineation purposes. Specifically, depth intervals for all new sampling stations, or in areas where additional vertical delineation is needed, will be: 0 to 0.5 feet; 0.5 to 1.0 feet; and 1.0 to 1.5 feet. Additional proposed soil sampling locations for the Canyon Creek Trestle project area are depicted on Figure 2. The additional sample locations have been selected with the objective of further ...
Soil Sampling. From each borehole location, both surface and subsurface soil samples will be collected (SOP OP-005, App. B). These samples will be screened in the field laboratory to ensure areas exhibiting substantially elevated gross gamma count rates have received representative sampling effort. Samples that are designated as record samples will be sent to Paragon for analysis. Some samples (5 total) will be sent for TCLP characterization, and other characterizations deemed necessary, to assist in determination of acceptable waste disposal options during NTCRA design. Surface sample(s) will also be obtained from the Chartley Swamp periphery to supplement the gross gamma walkover survey (GWS) that will be performed in that area (see below). Additionally, 8 surface and 3 subsurface soil samples will be collected by ERM from locations X-X in accordance with their FSP and QAPP for this site. Samples will be collected and preserved as appropriate and transferred via chain-of-custody to XXXXXXX on-site personnel for shipment to Paragon for analysis of radiological contaminants. Results from this investigation will aid in determining the nature and extent of radiological contamination that would be addressed by a NTCRA.
