The Coal Authority (CA) is commissioned by Cyfoeth Naturiol Cymru (Natural Resources Wales - NRW) to undertake engineering interventions for the remediation of pollution by abandoned metal mining at and around Nant y Mwyn Mine, Carmarthenshire. The interventions include the assessment of blow-out potential, and minewater treatment from the historic Deep Boat Level Adit.

The works comprise installation of a borehole to intercept the Nant y Mwyn Deep Boat Level Adit.
