In cases where drainage from a mine is not acidic and has dissolved metals or metalloids, or was originally acidic, but has been neutralized along its flow path, then it is described as "Neutral Mine Drainage", "Mining-Influenced Water" or otherwise.
Nos casos nos que as drenaxes procedentes dunha mina non son ácidas e levan metais ou metaloides disolvidos, ou eran orixinalmente ácidas, pero foron neutralizadas durante o traxecto seguido polo fluxo, entón denomínanse "drenaxes neutras de minas", "auga influenciada pola minaría" ou doutros modos.
