Shungite application for treatment of drinking water – is it the right choice?

Please find below a link to a Scientific Paper on Shungite Water. Also, see below for the summary of the paper for your reference.
“Shungite is a natural carbon-containing material widely used in water treatment. Scientific research shows that shungite has good adsorption properties towards various organic compounds and heavy metals and exhibits antibacterial properties. Unfortunately, at the same time, shungite releases various chemical elements into the water, including heavy metals. In this study, changes in the concentration of various heavy metals during drinking water treatment with one commercial and one non-commercial shungite sample were determined. Also, the Cu(II) sorption with an initial concentration of 2,500 μg/L onto shungite was investigated. The results showed that heavy metals like nickel, copper, lead, cadmium, zinc, chromium and arsenic leach from shungite into water. Lead and cadmium exceeded the maximum acceptable concentration in drinking water for a few days, but nickel exceeded for up to 2 weeks. At the same time, shungite showed good adsorption properties towards copper. Nevertheless, before using shungite in drinking water treatment, it would be advisable to assess the necessity and wash shungite with larger volumes of water for a longer period than is written in the instructions.”
