Document Summary
Permanganates: sodium is a contaminant, that can cause elevated electrical conductivity and sodium adsorption ratio. Measure ground water alkalinity when treating water with hydrogen peroxide. Concerns: it can be toxic to micro-organisms so it might not be the best oxidizer to group together with something. It creates a lot of heat so it could be done in the winter time although with the heat it could be a concern if there are impermeable surfaces like concrete, the heat needs to be released. ph limited. Not overly a good approach in alberta and sask. Manganese dioxide is a product and naturally occurs. Water soluble and good with a range of ph and it wont eat up all the carbon, not toxic to microbes. Not good with elevated salinity, monitor ground water and water as remediation is occurring. It is a gaseous form and you need equipment on site to create the ozone.
