“…Therefore, it is anticipated that the cost for management of this sludge is rather insignificant. Similar to our results, others have also reported that microbial Cr(VI) removal was solely attributed to biotic processes that tend to reduce Cr(VI) to Cr(III) anaerobically …”

“…All these methods present several disadvantages such as high capital and operational cost, production of chemical sludge, sludge disposal problems, etc . Despite the extensive literature regarding the physicochemical methods for Cr(VI) removal from water, there is limited literature on the biological treatment of groundwater for Cr(VI) removal . On the other hand, microbial reduction of Cr(VI) to Cr(III), has been extensively reported in the literature for the treatment of liquid wastes under anaerobic conditions, due to its low operational cost, its effectiveness and its low production of chemical sludge.…”

BACKGROUND: Microbial reduction of Cr(VI) to the much less toxic Cr(III), although practiced for the treatment of liquid wastes has not been implemented for the treatment of groundwater due to the absence of electron donors (organic substrates) and the lack of data on inhibition of biological Cr(VI) removal. The objective of this work is to evaluate biological groundwater treatment systems that will achieve high Cr(VI) removal with addition of a low dose of organic substrate and to estimate inhibition of microbial Cr(VI) reduction under anaerobic and anoxic conditions.

Research on the process-based risk evaluation method of groundwater pollution for contaminated site

et al. 2015

A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a risk evaluation method for contaminated sites. The present and forecasted groundwater pollutant concentrations and the variation trend of groundwater quality were used to get the risk classes of groundwater pollution. Chromium is one of the most common groundwater contaminants found at industrially contaminated sites. A chromium residue disposal site in Baotou, China was selected as the study area. The groundwater flow model and solute transport model were constructed by MODFLOW and MT3DMS. Based on the simulation results of the numerical model, the groundwater pollution risk of the contaminated site was divided into four classes, and the regulation measures of groundwater pollution were suggested. This study could provide guidance for the environmental supervision and management of contaminated sites.
