Water management solutions for the international mining community since 1984

M&A’s range of services supports all phases of the mining process from exploration, feasibility, and permitting to operations and closure. Our professionals have developed innovative methods to characterize aquifers, model dewatering, conduct water balances, and support operations. We develop monitoring programs and numerical models to support permitting, and we design wells for characterization, monitoring, water supply, and dewatering.
