Earth Systems provides total water quality management solutions, from characterisation to treatment, and is committed to outcomes that are in the best interests of the environment and human health.

We have successfully completed surface water and groundwater quality projects in all Australian states as well as in China, India, Indonesia, Laos, Papua New Guinea, New Zealand, Philippines, Tanzania, Mali, Senegal, South Africa, Argentina, Peru and the U.S. We provide expert advice and innovative solutions to a range of water quality issues including metal pollution (Cu, Pb, Zn, Fe, Al, Mn, As, Sb, Cd, Co, Ni, Ag, CrIII), turbidity, cyanide contamination, acid, salinity (Cl, SO4, SCN), nutrients, BOD, COD, alkalinity and odour.

We have specialist expertise in managing Acid and Metalliferous Drainage (AMD).
