field parameters may not be collected as these conditions can be detrimental to the field parameter <br /> unit. <br /> C. Sample Collection <br /> Samples will be collected directly from the surface water at the same locations mentioned above. A <br /> new un-used poly container included in the sample kit will be triple rinsed and utilized to transfer the <br /> surface water to sample containers that contain a preservative. When transferring water to the smaller <br /> containers, special precaution will be taken to prevent overfilling and diluting the container <br /> preservation. <br /> Containers requiring zero headspace will be checked to ensure that no bubbles are present exceeding <br /> the laboratory specifications. If a bubble is observed, the sample will be retained and remain within <br /> the container as it contains an acid preservation. However, a second container will be filled to fulfill <br /> the laboratory container requirements. Both samples will be submitted to the lab for proper <br /> management. <br /> VI. Sampling Analysis <br /> After a baseline of analysis that was established through the investigation process, sampling and analysis of <br /> each sample location will consist of the following constituents; <br /> • Diesel Range Organics (DRO) Method 8015C <br /> • Gasoline Range Organics(GRO) Method 8015D <br /> • Poly-Aromatic Hydrocarbons (PAH) Method 846 8270D <br /> • Benzene, Toluene, Ethylbenzene, Total Xylenes (BTEX) Method 8260C <br /> Additional analysis will be added as requested by regulatory agencies or as needed to evaluate other parameters <br /> of water quality. <br /> Samples will be submitted to ALS Global, USA. All samples will be on a standard five (5) business day turn, <br /> unless rush analysis is required, at which time 24-hour reporting will be requested from the lab. Should ALS <br /> be unable to meet the demands of the project, an alternate NELAP lab will be identified and approved by <br /> personnel assisting with this project and regulatory agencies before utilization. <br /> VII. Conclusion <br /> The information above is designed to outline the sampling procedures and processes to monitor the water <br /> quality in Yule Creek and ensure no impacts are occurring downgradient of the spill area exceeding regulatory <br /> thresholds. Monthly sampling of Yule Creek is planned for a 12-month period (January — December 2020), <br /> allowing for a full year of analysis and monitoring covering all the seasonal water fluctuations.When 12 months <br /> of sampling is complete, a summary of the surface water data will be compiled into an annual report. Should <br /> contaminant concentrations remain below regulatory threshold limits for a 12-month period, sampling <br /> frequency will be reduced to quarterly. Quarterly sampling will continue until four consecutive(4) quarters of <br /> data are below regulatory thresholds. <br /> 5 <br />
