Subject: Sampling and Analysis Plan (Field Sampling Plan and Quality Assurance Project Plan)

Amendment 2016 Annual Groundwater Sampling and Reporting For Site 3 at NSA Mechanicsburg, PA Contract No. N40085-10-D-9407 Watermark Project No. 10407-05

Dear Mr. Murray:

Watermark Environmental, Inc. (Watermark) has reviewed the “Sampling and Analysis Plan (Field Sampling Plan and Quality Assurance Project Plan) for Annual Groundwater Monitoring at Site 3 – Ball Road Landfill and Burn Pits” dated June 2008, the 2012 Amendment to the plan, and the 2015 Amendment to the plan. The Sampling and Analysis Plan/Quality Assurance project Plan (SAP/QAPP) outlines the quality objectives and describes a comprehensive set of sampling, analysis, quality assurance/quality control, and data validation guidelines. Watermark intends to utilize this document for the 2016 Annual Groundwater Monitoring activities at Site required under Contract No. N40085-10-D-9407, with the changes from the 2012 and 2015 amendments to the SAP/QAPP, and with the enclosed changes.

If you have any questions or require additional information, please feel free to contact me at (781) 681-4311.

Sincerely, WATERMARK

Katie Thomas, PMP Project Manager
