Water Treatment with Biochar from Josh Kearns on Vimeo.

From their web site,active field and laboratory research projects include:

  • applicability of indigenous charcoals and biochar materials for water treatment targeting pesticides and other hazardous synthetic organic compounds.
  • indigenous charcoal / biochar applications in eco-sanitation and composting latrines
  • bio-filtration systems: design and monitoring of slow-sand/bio-sand and bio-carbon water filters
  • intermittent flow-through solar disinfection (SODIS) systems
  • development of field-based analytical methods and best practices for water quality monitoring and treatment system evaluation

Contamination of drinking water sources by synthetic organic compounds (SOCs – e.g. pesticides, pharmaceuticals, fuel compounds) is a growing worldwide problem. Many of these chemicals bio-accumulate in the human body and cause cancer, birth defects and diseases of the reproductive system, and disrupt endocrine and neurological systems. However, few low-cost, sustainable and appropriate treatment technologies are available to rural and developing communities for SOC removal. Moreover, SOCs are rarely or not-at-all addressed in the majority of safe drinking water programs implemented by major international development NGOs and government agencies, university research programs, philanthropic organizations, non-profits, faith-based charities, etc.
