The list should be updated based on monitoring results and information on possible pollution of river water by contaminants (e.g., from an industrial source) (2) Actual monitoring time and location will be decided by DWASA and the Design Supervision Consultant (DSC) and included in the Employer’s Requirements. (3) The estimated costs are based on current rates charged by BRTC, BUET for analysis of the parameters.
