Consultant will summarize the regulatory requirements for permitting and construction of a new groundwater well, including water quality testing requirements, Drinking Water Source Assessment and Protection Program requirements, and design considerations, including treatment requirements (i.e., for iron and manganese, with potential blending to reduce TDS). Consultant will develop an anticipated timeline for well design, construction and permitting, as well as conceptual construction and operational costs for a groundwater well. A qualitative discussion of treatment requirement and costs will also be included (i.e., conceptual -level construction and operational costs estimates for groundwater well treatment). Subtask 2.5 Prepare Draft and Final Technical Memorandum Consultant will develop a brief summary technical memorandum (TM) to summarize the results of Subtasks 2.1 through 2.4 (i.e., potential groundwater yield and costs and process to install a well).

Upon receipt of comments, Consultant will finalize the TM.
