Whether the acid was leached from the ground, or as a result of an ,industrial, waste, the ACTI-Mag was able to make use of the high surface area to rapidly neutralise the acid contamination. There are plenty of alternative chemicals on the market that promise acid neutralisation, but there is nothing that delivers the results as quickly and as cost effectively as ACTI-Mag.
