6) Deliverables: Liner design and installation inspection, water sample reports, technical memorandum.
Reason for Change Order:
Well 16 production well is scheduled for replacement due to exceedence of the Uranium MCL and poor
condition of the well casing. During the course of design work on Well 16B test well, the consultant made
some discoveries about how the original production well construction methods might be contributing to the
high Uranium levels encountered. The consultant made a verbal request to the City PM to accomplish the
work stated above. This work was not only potentially valuable as a temporary correction for the existing well,
but also to understand the underlying sub-aquifer geochemistry which is an objective of the current Task
Order. For this reason, City PM agreed and made a verbal work directive to accomplish this work under the
current Task Order.
