Hi Kgabo, Any treatment ...

Hi Kgabo,

Any treatment without addressing the source of the contamination will only supply a small, clean supply of water without addressing the health for those that  normally come into contact with the water.  Using halogen-based disinfectants will result in undesirable disinfection by-products increasing long-term, chronic health risks.  In my opinion, one should identify the source of the contamination, stop, or limit that source, and then use natural processes to rehabilitate the river system.  This moves into the municipal and political ambit which is fraught with inefficiencies, and where the political will to address the problem is crucial.  Water activism is not well-developed in our country, but intelligent, well-directed activism has its place in our communities.
