Shungite can remove from water almost all organic compounds (including pesticides), metals, bacteria and harmful microorganisms. Experiments were undertaken with Shungite being introduced into water contaminated with Streptococcus A and D. The results of the experiment showed that after half an hour the Shungite had reduced the concentration of Streptococcus D in the water by the factor of 100 and Streptococcus A by the factor of 900! Shungite eliminates or reduces various chlorine compounds, nitrates, copper, magnesium, iron, cleans up visually dirty water and eliminates taste, after all water should be tasteless!
