“…With ∼12 freeze–thaw cycles per year in the top 30 cm of Antarctic soil (S. Ferguson, Australian Antarctic Division, unpublished observations), ongoing release of total NH 3 and K + at 100 freeze–thaw cycles demonstrates the long‐term suitability of Zeopro™ to promote PHC degradation. However, it must be noted that while this experiment was conducted in deionised water, cations in groundwater and particle colonisation by microorganisms may alter the release rates of total NH 3 and K + from Zeopro™ .…”

Cold region soils are often devoid of sufficient nutrients essential for timely bioremediation of petroleum hydrocarbon contaminants. While materials that release nutrients in a controlled manner have been shown to stimulate biodegradation over extended time periods, the physical and chemical response of these materials to repetitive freeze-thaw stresses typical of cold regions remains poorly understood. This study reports the performance of four controlled release materials in water (Osmocote TM , Nutricote TM , Polyon TM , Zeopro TM ) exposed to freeze-thaw cycling or control temperature of 4°C. Additionally Zeopro TM -activated carbon mixtures are investigated for application to permeable reactive barriers. Osmocote TM experienced higher nutrient release under control conditions compared with samples exposed to freeze-thaw after 20 days. Nutrient release from Nutricote TM and Polyon TM was similar under freeze-thaw and control conditions. Zeopro TM delivered low nutrient concentrations into solution in both freeze-thaw and control samples with calcium phosphate dissolution accelerated in the presence of activated carbon. Osmocote TM , Nutricote TM and Polyon TM revealed strong resistance to breakdown under freeze-thaw. Zeopro TM experienced only partial disintegration, while significant break-up of activated carbon occurred under freezethaw. A physical and chemical understanding of the response of multiple fertilisers can guide the selection of materials for biostimulation and biodegradation of petroleum hydrocarbons in environments exposed to freeze-thaw cycling.Abbreviations: CRN, controlled release nutrient; FESEM, field emission scanning electron microscopy; GAC, granular activated carbon; ICP-OES, inductively coupled plasma-optical emission spectrometry; PHC, petroleum hydrocarbon; PRB, permeable reactive barrier.

The provision of safe water for people is a human right; historically, a major number of people depend on groundwater as a source of water for their needs, such as agricultural, industrial or human activities. Water resources have recently been affected by organic and/or inorganic contaminants as a result of population growth and increased anthropogenic activity, soil leaching and pollution. Water resource remediation has become a serious environmental concern, since it has a direct impact on many aspects of people’s lives. For decades, the pump-and-treat method has been considered the predominant treatment process for the remediation of contaminated groundwater with organic and inorganic contaminants. On the other side, this technique missed sustainability and the new concept of using renewable energy. Permeable reactive barriers (PRBs) have been implemented as an alternative to conventional pump-and-treat systems for remediating polluted groundwater because of their effectiveness and ease of implementation. In this paper, a review of the importance of groundwater, contamination and biological, physical as well as chemical remediation techniques have been discussed. In this review, the principles of the permeable reactive barrier’s use as a remediation technique have been introduced along with commonly used reactive materials and the recent applications of the permeable reactive barrier in the remediation of different contaminants, such as heavy metals, chlorinated solvents and pesticides. This paper also discusses the characteristics of reactive media and contaminants’ uptake mechanisms. Finally, remediation isotherms, the breakthrough curves and kinetic sorption models are also being presented. It has been found that groundwater could be contaminated by different pollutants and must be remediated to fit human, agricultural and industrial needs. The PRB technique is an efficient treatment process that is an inexpensive alternative for the pump-and-treat procedure and represents a promising technique to treat groundwater pollution.

“…The effectiveness of petroleum hydrocarbon adsorption materials such as granular activated carbon (GAC) in PRBs has been well reported (Karanfil and Kilduff, 1999;Arora et al, 2011;Mumford et al, 2015). However, in the absence of biodegradation, the finite adsorption capacity of GAC presents issues associated with breakthrough, regeneration and disposal as a hazardous material.…”

“…Controlled release nutrient (CRN) materials are therefore important for the sustained delivery of essential nutrients to particle-attached biofilms in PRBs (Freidman et al, submitted for publication). Mumford et al (2013Mumford et al ( , 2014Mumford et al ( , 2015 report the first application of soluble and nutrient-amended zeolite CRN materials to promote biodegradation in a sequenced PRB at Casey Station, Antarctica. Total petroleum hydrocarbon concentrations, degradation indices and microbial analyses support the application of CRN materials to promote biodegradation within PRBs .…”
