Sourcing Organic Materials for Pit Lake Bioremediation in Remote Mining Regions

Pit lakes formed by open-cut mining may have poor water quality as a result of Acidic and Metalliferous Drainage (AMD). Water quality remediation treatments that enhance naturally occurring alkalinity-generating processes (bioremediation) can be used to remediate these water quality problems. Microbially-mediated sulphate reduction using carbon as an electron donor is one approach that shows promise. Carbon amendment can be bulk organic materials, which are often cheap or free. This study investigated a process for determining what organic materials were best for in situ pit lake AMD bioremediation in a remote mining region. Following a literature review identifying how different organic materials facilitated sulfate reduction in AMD waters, we evaluated availability and costs of acquiring and transporting these materials to a typical remote mine pit lake. We found that those sourcing organic materials should focus on a mixture of sewage sludge and green waste, which are commonly available from mining camps/service towns and from land clearing operations

“…The whole variety of substrates has been used in many studies mostly methanol [8,9], acetate [1,10], ethanol [11,12], and acetic acid [13,14]. Numerous different industrial waste products were tested, i.e., molasses [15,16], glycerol as a byproduct of biofuels production [17][18][19].…”

The aim of the present work was to study the applicability of the activated sludge from a municipal wastewater treatment plant for high strength nitrate denitrification process. A sequenced batch reactor operated at initial nitrate concentration in the range from 750 to 8500 mg 3 3 NO -N/dm . − The effectiveness of various carbon sources on denitrification rate and nitrite accumulation was studied. The average specific denitrification rate was in the range from 58 to 62 mg 3 NO -N/(g VSS•h) − for ethanol, glycerol, molasses and whey. The denitrification with methanol was not effective.

“…Denitrification can be enhanced by adding carbonaceous materials to soil (Alexander 1977). Peat moss (Winkler 1991), molasses (Ueda et al 2006), and sawdust (Schipper et al 2000(Schipper et al , 2005 have been successfully used to reduce nitrate concentrations in septic systems. Jordan et al (1998) reported a ten-fold increase in denitrification in riparian forest soil amended with sucrose and Wang et al (2007) showed enhanced denitrification in lake sediment after adding sucrose.…”

Agrichemical spills and discharges to soil can cause point-source contamination of surface and ground waters. When high contaminant concentrations inhibit natural attenuation in soils, chemical treatments can be used to promote degradation and allow application of treated soils to agricultural lands. This approach was used to remediate soil containing >650 mg atrazine, >170 mg metolachlor and >18,000 mg nitrate kg −1 . Results indicated a decrease in metolachlor concentration to <1 mg kg −1 within 95 days of chemical treatment with zerovalent iron (Fe 0 , 5% w/w) and aluminum sulfate (Al 2 (SO 4 ) 3 , 2% w/w) but after one year >150 mg atrazine and >7000 mg nitrate kg −1 remained. Laboratory experiments confirmed that subsequent additions of sucrose (table sugar) to the chemically pretreated soil promoted further reductions in atrazine and nitrate concentrations. Field-scale results showed that adding 5% (w/w) sucrose to windrowed and pretreated soil significantly reduced atrazine (<38 mg kg −1 ) and nitrate (<2,100 mg kg −1 ) concentrations and allowed for land application of the treated soil. These results provide evidence that zerovalent iron in combination with Al 2 (SO 4 ) 3 and sucrose can be used for on-site, field-scale treatment of pesticide-and nitrate-contaminated soil.
