The gasification of rice husks for small-scale power generation inrice mills and other small factories in Cambodia has spread rapidly in the pastdecade and has a favourable investment payback period where the facility isoff-grid. The technology is widely regarded as a sustainable, low-carbon poweroption. However, installed gasification technologies produce a black wastewater which is frequently disposed of into the local environment without anytreatment. An analysis was undertaken to identify and measure the keypotential contaminants and compare concentrations in the water and sedimentwith regulatory thresholds established in Cambodia and within otherjurisdictions. It was found that concentrations of organic contaminants such asphenols and benzene-type molecules (BETX) (water and sediment) andpolycyclic aromatic hydrocarbons (PAHs) (sediment), as well as macro waterquality indicators, were far higher than regulatory thresholds prescribe, posingthreats to sensitive aquatic ecosystems into which such waste is introduced
