  • Toxic effects of combined stressors on Daphnia pulex: Interactions between diazinon, 4‐nonylphenol, and wastewater effluent

    Contaminant exposure in aqueous systems typically involve complex chemical mixtures. Given the large number of compounds present in the environment, it is critical to rapidly identify hazardous chemical interactions. This study utilizes a prototype for a novel high throughput assay to quantify behavioral changes over time to identify chemical interactions that affect toxicity. The independent ...

  • Treatment Alternatives for Liquid Penetrant Rinse Waters

    Explores the options available to process wastewater generated from liquid penetrant inspection. Rinse waters containing residues from the penetrant inspection process are generated from all but Method C (solvent removal).  The rinse water contains penetrants (Method A), or penetrants and emulsifier (Methods B and D), which contain oils and surfactants.  The water may also contain ...

  • The REACH Pandemic

    The world over, countries are adopting the core elements of REACH, Europe’s three-year-old regulation on chemical use. As the EC’s Environment Commission states, REACH aims to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances . But what it says next is equally important: ...

  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...


  • "Don`t waste a drop" - water in mining

    Christopher Gasson explains the complex relationship between the mining industry and global water supply Water has always been important for mining, but suddenly it has become a board-level issue. Shareholders now expect companies to have identified the operational and environmental risks they face as a result of their water usage, and show that they are pursuing strategies to minimise this ...

  • Can incentives protect Canada’s clean water?

    Clean water is a vital, valuable resource for Canada. We drink it. We grow food with it. We generate power using it. We use it as an input to industry, from manufacturing to oil and gas production. We swim, splash, and paddle our canoes in it. And clean water isn’t valuable just to humans; it also underpins essential ecosystems all over the country. But do our policies reflect the ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...
