ENAMI asked the drilling company ANDINOR for a specialized hydrogeological advisory to elaborate the design of different monitoring wells due to a requirement made by the Environmental Authority with the purpose of recording potential acid runoff from the tailing dam N°3 at Matta Plant, Paipote.

All the information gathered previously during the wells construction was analyzed, describing the drilling samples and complementing the design according to what the client needs.

As a result, we handed installation proposal reports for each construction work. Those reports included all the information gathered and generated during the field technical inspections to Paipote. The reports were approved by the Technical Inspection Delegation and they served as a baseline to the definite construction of the wells.
