This paper discusses the environmental effects due to nickel mining. Conclusions were drawn in regards to unmonitored mine waste that can lead to grave environmental predicaments, such as that of acid mine drainage being the result of the change from iron (II) to iron (III). This change ultimately leads to the contamination of neighboring streams, lacks, and underlying aquifers that end up being detrimental to the surrounding inhabitance. Moreover, the transport of toxic chemicals throughout the atmosphere, which will then deposit on surfaces of neighboring soil, results in an increase in soil acidity due to the increase in H+ ions making it impossible for most vegetation to survive. The aftermath is becoming more evident, as numerous case studies are performed in order to determine any possible means of reclamation. As more evidence surfaces, more attention is given to ways of preventing or improving the effects to the environment.
