Effects of acids and alkalis on aquatic life - Lenntech

Limestone can buffer (neutralize) the acidification of freshwater. The effects of acid deposition are much greater on lakes with little buffering capacity. Much of the damage to aquatic life in sensitive areas with this little buffering capacity is a result of ‘acid shock’.

Lime/limestone neutralisation Both limestone and lime are needed during treatment of acid mine waters. Benefits associated with limestone are its low cost compared to other alkalies (Table 1), automatic dosage control (in the case of a fluidised-bed reactor) as limestone only dissolves at pH-values below 7.5, and limestone is safe to handle.
