Nitrate leaching can have a direct impact on water quality. Nitrate is very mobile and easily leaches with water. Heavy rains can cause nitrates to leach downward in the soil below the root zone. Whether nitrates continue to leach downward, and into groundwater, depends on underlying soil and/or bedrock conditions, as well as depth to groundwater.

The introduction of lead nitrate resulted in a 2.28% increase in extraction. Studies have shown that the addition of lead nitrate can be beneficial to gold leaching kinetics. Lead passivates the surface of reactive sulphides and forms insoluble lead sulphide, thus effectively preventing the solution from contacting the sulphides.
