THE LOCATION OF CONNECTION TO THE NEW PIPE FROM THE NEW WELL PRIOR TO

HAVING THE DISCHARGE DROP PIPE FABRICATED.

DIMENSIONS OF FABRICATED DISCHARGE DROP PIPE SHALL BE COORDINATED BY

CONTRACTOR WITH THE MANUFACTURER. CONTRACTOR SHALL VERIFY THE

DISTANCE BETWEEN THE FLOW CONTROL SPOOL SLAB AND THE CENTER OF THE

EXISTING IRRIGATION MAIN.

THE DESIGN TEAM PROVIDED AN IRRIGATION SUPPLY WELL DESKTOP EVALUATION

(ECS), DATED JANUARY 21, 2022 (PROJECT MANUAL, APPENDIX III) AND AN

IRRIGATION SUPPLY WELL DEPTH EVALUATION (ECS), DATED MARCH 29, 2023

(PROJECT MANUAL, APPENDIX IV). THE DESIGN TEAM UNDERSTANDS THE

GOVERNMENT WOULD LIKE TO INSTALL A NEW IRRIGATION SUPPLY WELL AT THE

SITE THAT IS CAPABLE OF PRODUCING 1,500-2,000 GALLONS PER MINUTE (GPM) AT A

MAXIMUM DEPTH OF 400 FEET BELOW GROUND SURFACE (BGS). AS SUCH, THE WELL

DESIGN AND SPECIFICATION DOCUMENTS CONTAINED WITHIN THE PREVIOUSLY

SUBMITTED IRRIGATION SUPPLY WELL DESKTOP EVALUATION HAVE BEEN REVISED

(ASI 01) BASED ON FINDINGS FROM THE IRRIGATION SUPPLY WELL DEPTH

EVALUATION. THE IRRIGATION SUPPLY WELL DEPTH EVALUATION INCLUDED A

RECOMMENDATION THAT A STEP-DRAWDOWN PUMPING TEST OF THE SITE'S

EXISTING IRRIGATION SUPPLY WELL BE PERFORMED TO EVALUATE WHETHER THE

UPPER MAGOTHY AQUIFER APPEARS CAPABLE OF MEETING THE GOVERNMENT'S

WATER DEMAND OF 1,500-2,000 GPM. THE DESIGN TEAM HAS SINCE BEEN INFORMED

THAT THE GOVERNMENT WOULD LIKE TO PROCEED WITHOUT PERFORMING THE

RECOMMENDED STEP-DRAWDOWN PUMPING TEST. AS SUCH, IT IS IMPORTANT TO

RECOGNIZE THAT THE SPECIFICATION DOCUMENTS WERE DEVELOPED BASED ON

THE ASSUMPTION THAT THE ESTIMATED MAXIMUM WELL DEPTH OF 400 FEET BGS

WILL BE ADEQUATE TO MEET THE GOVERNMENT'S WATER DEMAND OF 1,500-2,000

GPM. WHILE OUR PRIOR EVALUATIONS DO INDICATE THAT A WELL COMPLETED TO A

DEPTH OF 400 FEET BGS WOULD LIKELY PROVIDE THE DESIRED PRODUCTION OF

1,500-2,000 GPM, IT IS IMPORTANT TO NOTE THAT SOME LEVEL OF UNCERTAINTY

DOES EXIST DUE TO A GENERAL LACK OF INFORMATION REGARDING THE EXISTING

WELL'S PRODUCTIVITY AND A LACK OF AVAILABLE OFFSITE WELL LOGS IN PROXIMITY

TO THE PLANNED WELL LOCATION.
