Groundwater Sampling. Prior to the date hereof, Sellers have sampled water from the existing deep well located at the Easton, Pennsylvania facility and have had that sample analyzed for volatile organic compounds. Sellers have provided Buyer with a written report describing the results of such sampling and analytical results and Buyer acknowledges receipt of such report.
Groundwater Sampling. The shallow groundwater was sampled to determine if there is a source of PCE impacting groundwater near the groundwater sampling locations and if PCE or decay products are present at levels that indicate a potential threat to indoor air via vapor intrusion or to downgradient water use. Based on reviews of previous work it was expected that the groundwater would be present at shallow levels (<10 feet). In fact, it was quite difficult to retrieve water from the temporary borings at this site that were completed to 14-17 feet of depth. Soils in the cored areas also contained significant clay and silt, which likely impeded flow into the borings. Groundwater samples were successfully recovered from borings SB-1, SB-3 and SB-4. Groundwater collection was unsuccessful at borings SB-2 and SB-5. The sample designation for groundwater samples is “GW” followed by the boring number. Thus, the sample designation for the groundwater sample from boring SB-2 would be “GW-SB2”. Groundwater was encountered at depths ranging from 10 to 15 feet below ground surface. PVC well casing was used to collect water samples. This approach involved temporarily installing cleaned ¾-inch threaded PVC well screen and blank into the open borings after removing the soil sampling tools. This was possible because the boreholes tended to stay open to allow the PVC to be installed. This method provided additional time for water to enter the borings while the next boring was initiated. Five feet of machine-slotted well screen was used at the base of each temporarily well. Filter pack was not installed around the temporary xxxxx. Groundwater entered the temporary xxxxx which allowed for purging and sample collection as described below. After groundwater samples were collected the PVC casing was removed and steam cleaned before being re-used. Prior to purging water or collecting water samples from each boring, water levels were recorded with an electric water level meter. The measurements were made relative to the ground surface. Where possible, prior to collecting groundwater samples, water was purged from the temporary xxxxx. SB-3 was purged using a Mechanical bladder pump with clean, disposable tubing (Geoprobe MBP470). About 1 liter of water was purged from SB-3 prior to sample collection. The water sample from SB-3 was collected from the tubing above the mechanical bladder pump directly into 3 40-milliliter VOA vials, and an additional 3 vials were collected for a replicate sample. SB-1 and S...
Groundwater Sampling. Groundwater samples will be collected from monitoring xxxxx and irrigation xxxxx, following the methods described in the Revised Work Plan. New groundwater monitoring xxxxx will be allowed to set for at least 24 hours prior to initiating well development. Xxxxx will be developed by over-pumping to remove excess turbidity and improve hydraulic communication with the adjacent water-bearing zone. Following installation of the new xxxxx, NuStar will perform a comprehensive groundwater sampling event that includes all monitoring xxxxx at the Site and approximately 16 irrigation xxxxx. Monitoring and irrigation xxxxx scheduled for sampling1 are shown on Figure 2. If additional irrigation xxxxx are identified in the investigation area, NuStar will attempt to obtain permission to collect a water samples from those xxxxx. During the monitoring event, groundwater levels will be measured in monitoring xxxxx and selected inactive irrigation xxxxx. The groundwater samples will be analyzed for GRO by Method IA OA-1 and VOCs using EPA Method 8260B. Well Location and Surveying. The horizontal locations and elevations of the new monitoring xxxxx and select irrigation xxxxx will be surveyed by a Kansas-licensed land surveyor. Top-of-well casing and cap elevations will be reported to the nearest hundredth of a foot, relative to mean sea level (MSL). SOIL VAPOR SAMPLING In accordance with our project discussion on September 11th, one round of soil vapor samples will be collected from soil vapor monitoring points VP-1 through VP-3; the locations of the vapor points are shown on Figure 3. Soil vapor monitoring point construction and sampling methodology are consistent with previously KDHE-approved work plans (Apex, 2013); additional detail will be provided to KDHE in a subsequent deliverable. In general, the sampling methodology will consist of: Leak detection, which will include a pressure test and helium tracer test. Soil gas samples will be collected in 1-liter Summa canisters at an approximate rate of 30 milliliters/minute over a period of less than approximately 30 minutes. Split samples may be collected by KDHE; in that case, the total flow rate must remain less than 200 milliliters/minute. The soil vapor samples will be analyzed for VOCs (benzene, 1,2-dicholoethane, ethylbenzene, naphthalene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, xylenes, n-butylbenzene, and n- propylbenzene) using EPA Method TO-15. Analytical results will be used for a pre...
Groundwater Sampling. Respondent shall sample and analyze groundwater from the nearby Iivestock well DWR6T519, or report the sampling results from another agency if they exist, for uranium and a full metals suite.
Groundwater Sampling. Groundwater samples will be collected from the GeoProbe or HSA borings utilizing clean disposable bailers or a peristaltic pump with clean disposable tubing. Prior to sample collection, each temporary well will be purged of no less than three (3) casing volumes of groundwater or until the water sample is free of silt. Low flow sampling will not be conducted and groundwater stabilization parameters will not be measured or recorded. Water samples will be collected in three acid preserved 40-xx xxxxx vials. As specified in the RFP, the protocol for selecting groundwater samples for laboratory analysis will be based on the following priority system (1 the highest priority and 8 the lowest priority):
Groundwater Sampling a subset of groundwater monitoring locations will be analyzed for PCBs, SVOCs and pesticides to evaluate whether these constituents are present in groundwater. Section 4.4.4.3 of the RI/FS Work Plan has been updated to include these locations, which include the OU 1 Post-Site Closure Monitoring locations as well as select bedrock and overburden monitoring locations proposed to be installed along Transect 1 during the hydrogeological investigation. The results will be compared with historic groundwater data to understand the extent of impacts of these contaminants and evaluate the necessity of inclusion of these analyses in future groundwater monitoring.
Groundwater Sampling. 1) Groundwater sampling of all on‐site monitor xxxxx will occur on a quarterly basis. Samples will be analyzed for Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds (VOCs) and Metals. March 5, 2021 Task 3: Reporting
