S.D. Admin. R. 74:29:05:15
Sampling of solution to be applied to the land shall consist of not less than one grab sample per 100,000 gallons of solution. If less than 100,000 gallons is to be applied to land, at least one grab sample must be taken and analyzed for the required parameters. Each grab sample must be of sufficient volume so the sample can be split. Each split of the sample must be of a volume sufficient to allow for analysis for all operational monitoring parameters. At every fifth sampling, one split sample of each five consecutive grab samples shall be composited and analyzed for the required monitoring parameters. The remaining split sample for all grab samples shall be preserved and stored for further individual analysis if analyses of composited samples indicate the presence of a concentration for a given parameter in excess of the criteria of § 74:29:05:08. Additional sampling in compliance with a quality assurance plan must be performed. Operational monitoring parameters shall be determined from the chemical characterization.
