This determination shall be made jointly by the applicant and the department based on site specific conditions at the time of testing. If high recharge conditions are present but postponing or prolonging the test is not reasonably feasible, the applicant shall include a justification for not postponing or prolonging the test in the final report and adjust the collected data using conservative assumptions to reflect average conditions.(d) The applicant shall postpone the pumping test if open pits used during well construction or any other depressions within 20 feet of the well contain standing water, or if the well site is flooded.(e) The applicant shall undertake water quality sampling in accordance with the approved proposal.(f) If the applicant wishes to change any aspect of the pumping test or water quality sampling program, the applicant shall submit a written request to the department that identifies the requested change(s) and explains why the change(s) should be approved.(g) The department shall approve a requested change if the modification does not affect the integrity of the data collected and the resulting modified testing protocol will produce the necessary information.N.H.
