Description:

The USGS Northern Appalachian Research Laboratory located in Wellsboro, PA has a requirement for a Phase II Environment Site Assessment. The contractor shall prepare a sampling and analysis plan to investigate potential contamination of soils, sediment, and water in accordance with the statement of work.

Task 1. Develop a Phase II Sampling and analysis plan: The Contractor shall prepare a sampling and analysis plan to investigate potential contamination of soils, sediment, and water. This plan shall be based on recommendations identified in the Conclusions and Recommendations of the Phase I Environmental Site Assessment prepared by Wood Environmental & Infrastructure, Inc.

Task 2. The Contractor shall submit the sampling and analysis plan to USGS for review, comment, and approval prior to implementing the plan. The plan shall specify contaminants of concern, including but not limited to mercury and PCBs, and the required testing standards and methods for the contaminants of concern. The plan shall be of sufficient detail to determine whether the site has residual contamination at a depth related to past land management practices.

Task 3. The Contractor shall recommend locations for sampling and prepare a map with proposed sampling locations as part of the sampling and analysis plan. Focused areas of concern include, but are not limited to, the water in the holding tank at the northern most boundary of the subject property.

Task 4. The Contractor shall participate in a conference calls, if needed, to answer questions regarding the sampling and analysis plan.

Task 5. The contract shall provide a GIS layer of the final sample locations.

Task 6. Conduct Field Sampling and Analyze Samples.

a) The Contractor shall provide all labor, equipment, and materials to collect surface and subsurface samples and water samples. The Contractor shall survey in all sample locations using recreation grade GPS accuracy standard of +- 5 meters and identify them on a map provided to USGS.

b) The Contractor shall conduct necessary laboratory tests to analyze soil and water samples for presence of contaminants

Task 7. Prepare Phase II report: The Contractor shall prepare a written report summarizing the findings of the sampling and analysis. The report shall include all analytical data in tables and maps showing locations of sampling with appropriate sample numbers and draw conclusions regarding the presence of contamination and provide supporting documentation for these conclusions. If contamination is detected, the Contractor shall provide recommendations and estimated costs for remediation.
