Drinking Water Management Act Article 15-1
For circumstances in which the use of a water body as a drinking water source or for drinking water is prohibited pursuant to Article 21 or Article 24, once the water intake organization or water supplier addresses the reason for placing a prohibition on the water body, a non-subordinate environmental analysis laboratory that has received a permit from the central competent authority shall carry out sampling of the water body that originally failed to meet water quality standards. The water body may resume serving as a drinking water source or as drinking water after the sample has been sent for testing and an environmental analysis report showing adherence to standards has been submitted to and approved by the organization that handles the review of the matter.
