“…Generally, constant monitoring of the microbial activity is also required to ensure constant and consistent microbial activity over time. For example, Adetutu et al (2015) utilised biostimulation (BS), biostimulation-bioaugmentation (BS-BA) and monitored natural attenuation (MNA) approaches to bioremediate groundwater polluted with trichloroethene (TCE). Next-generation D r a f t 5 sequencing was an effective technique to study the microbial community dynamics throughout while performing the dechlorination process.…”

The impact of contaminated leachate on groundwater from landfills is well known, but the specific effects on bacterial consortia are less well-studied. Bacterial communities in a landfill and an urban site located in Suzhou, China, were studied using Illumina high-throughput sequencing. A total of 153 944 good-quality reads were produced and sequences assigned to 6388 operational taxonomic units. Bacterial consortia consisted of up to 16 phyla, including Proteobacteria (31.9%-94.9% at landfill, 25.1%-43.3% at urban sites), Actinobacteria (0%-28.7% at landfill, 9.9%-34.3% at urban sites), Bacteroidetes (1.4%-25.6% at landfill, 5.6%-7.8% at urban sites), Chloroflexi (0.4%-26.5% at urban sites only), and unclassified bacteria. Pseudomonas was the dominant (67%-93%) genus in landfill leachate. Arsenic concentrations in landfill raw leachate (RL) (1.11 × 10 μg/L) and fresh leachate (FL2) (1.78 × 10 μg/L) and mercury concentrations in RL (10.9 μg/L) and FL2 (7.37 μg/L) exceeded Chinese State Environmental Protection Administration standards for leachate in landfills. The Shannon diversity index and Chao1 richness estimate showed RL and FL2 lacked richness and diversity when compared with other samples. This is consistent with stresses imposed by elevated arsenic and mercury and has implications for ecological site remediation by bioremediation or natural attenuation.

“…In recent years, mass sequencing of environmental samples has been at forefront of ecology and biodiversity research. Current advanced next-generation sequencing (NGS) technologies are providing new insights into the ecology of microbially mediated processes that influence fresh water quality such as algal blooms, contaminant biodegradation, and pathogen dissemination (Adetutu et al, 2015). Sequencing methods targeting small subunit (SSU) rRNA hypervariable regions have allowed identification of signature microbial species that serve as bioindicators for sewage contamination in these environments.…”

The quality of surface water in many parts of the world, especially in developing nations is being challenged by rapid economic growth, demographics and climate change leading to widespread and severe degradation of fresh water ecosystems. With many rivers still in good condition, there are opportunities to prevent pollution and begin restoration. However, severe organic pollution is already affecting around one in seven rivers across Latin America, Africa and Asia. This poses a growing risk to public and environmental health, food security and the economy. Freshwater systems in both developed and developing nations are facing growing pressure from the discharge of harmful chemicals, such as hormone disrupters. Unfortunately, municipal water treatment has become increasingly costly and developing countries in particular have problems matching expanding public water supplies and sewerage, with inadequate treatment facilities for the newer/higher wastewater flows. As a result there is a significant risk to vital activities like inland fishing, which accounts for some 60 million jobs and almost a third of fish harvested for human consumption. Yet, until now, insufficient collection and evaluation of data has made it difficult to grasp the intensity and scope of deteriorating water quality. Sound knowledge is critical to understanding the underlying causes and developing the evidence based policies to improve it, including source control, waste treatment, ecosystem management and new forms of local and global governance. By providing a snapshot of the current situation, success stories and future challenges, this review offers a baseline to measure progress, a framework for global assessment and a pathway towards sustainable solutions for river water remediation and restoration which will assist countries looking to establish their own planning, monitoring and guidelines.

“…Further a field in Victoria and South Australia, Australia the use of chlorinated compounds as thinners, cleaning and adhesive chemicals by the foam manufacturing industries has led to the formation of dense non-aqueous phase liquid (DNAPL) pools contaminating several groundwater aquifers over 3.5ha (Patil et al, 2014a). Earlier research carried out by Patil et al (2014a), Patil et al (2014b), Patil et al (2013) and Adetutu et al (2015) have reported the efficacy of a variety of methods for biological treatment of groundwater plumes from chloroethene contaminated site in Victoria, Australia. Following the recent successful trend of using these biological systems including bioremediation, phytoremediation and rhizoremediation, nanotechnology has recently been applied to environmental remediation (termed nanoremediation).…”
