  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • Time lapse resistivity/IP survey case study

    Changes in underground electric resistivity is typically resulted by the variations in groundwater conduction and soil water content. Monitoring this variation will help operator gain a better understanding of the underground water distribution over time.  This may facilitates operators monitor abnormal underground or structural behaviour. Time lapse resistivity survey is ...

  • Effect of bacterial growth stage on resistance to chlorine disinfection

    The mechanisms and factors that affect microbial resistance to chlorine disinfection have not been fully elucidated. In this study, we investigated the impact of the cell growth stage on chlorine disinfection efficiency. Specifically, we evaluated the impact of the growth stage on chlorination resistance by comparing the inactivation efficiencies of two indicator bacterial strains (Escherichia ...

  • New Advancements for In Situ Treatment Using Electrical Resistance Heating

    Abstract Electrical resistance heating (ERH) is proving to be an effective technology to rapidly heat the subsurface and, in doing so, removing volatile organic compounds. Practitioners of this technology have observed that other processes (biodegradation, abiotic degradation, hydrolysis, and possibly others) occur to break down the chemicals of concern, and remediation is not solely ...

  • Antibiotic resistance genes a growing problem in chinese estuaries

    Large amounts of antibiotic resistance genes (ARGs) have been found throughout estuaries in coastal China, and scientists say they’re causing potentially dangerous changes to local bacteria. When bacteria mutate and become resistant to antibiotics, it endangers human health and life. If antibiotics can’t work properly, infectious diseases will increase, and health-care costs will ...

  • Survival of antibacterial resistance microbes in hospital-generated recycled wastewater

    Hospital wastewater has the potential to be a threat to the hospital environment as it can contain pathogenic bacteria that may facilitate the resistant nature of organisms within effluent or water treatment plants. The recycling of hospital wastewater should have good quality. This study was carried out to highlight the incidence of antibiotic resistant bacteria in hospital-generated recycled ...

  • In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

    An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...
