  • Environmental Impact does NOT equal risk

    Auditing the new ISO 14001:2015:  Environment Impacts does not equal Risk In recent transition audits, there has been one common misconception that I have seen repeated, and that is that environmental impacts are risks.  This is not correct.  Environmental impacts do not equal risk. Let’s start ...

  • Influence of nanoparticles on filterability of fruit-juice industry wastewater using submerged membrane bioreactor

    In this study, polyethersulfone (PES) ultrafiltration membrane surface was modified with nano-sized zinc oxide (nZnO) and silver (nAg) to improve the membrane filterability of the mixed liquor and used to treat fruit-juice industry wastewater in a submerged membrane bioreactor (MBR). The nAg was synthesized using three different methods. In the first method, named as nAg-M1, PES membrane was ...

  • Rhode Island Wastewater Plants Key To Water Quality Reversal

    Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort. Take, for instance, Narragansett Bay, located on the north side of the Rhode Island Sound. Located near some of America’s oldest settlements, the bay has ...

  • A strategic framework for sustainable water resource management in small island nations: the case of Barbados

    Physical scarcity of freshwater is often given as the reason for water shortages, but it is usually its management that can either create or resolve the problem. This will be illustrated by the case of Barbados. The water management issues are typical of many small island states, some of which are particularly vulnerable to water scarcity, especially in the context of climate change. Barbados ...

  • Systematic risk management approach of household drinking water from the source to point of use

    The water safety plan (WSP) approach is being widely adopted as a systematic approach to improving the safety of drinking water. However, to date, the approach has not been widely used for improving the safety of drinking water in those settings where people have to collect water away from their home. Most rural areas in South Africa still consume unsafe water despite WSP implementation and ...

  • Innovative renewal strategies for optimized pipeline management

    Using risk-based data analysis and innovative renewal strategies, two US water systems show how utilities can avoid full pipeline replacement, reduce service interruptions, and save money. As this informative Opflow article discusses, by more precisely understanding the condition of buried infrastructure, water utilities can more effectively focus resources to prolong safety and increase ...

  • Influence of environmental variables on saxitoxin yields by Cylindrospermopsis raciborskii in a mesotrophic subtropical reservoir

    Saxitoxins are a class of toxins produced by at least two groups of evolutionarily distant organisms (cyanobacteria and dinoflagellates). While the toxicity of these toxins is relatively well characterized, to date little is known about their drivers and ecological functions, especially in lower latitude tropical and subtropical freshwater ecosystems. In the present study, we aimed to obtain a ...

  • Water masses surface temperatures assessment and their effect on surrounding environment

    The aim of this study was to evaluate the effect of water masses on the surface temperature with direct impact on the surrounding area. Three systems were used for the study: a fully vegetated system (subsurface flow constructed wetland (CW)), a lake with no vegetation and a lake partially vegetated with Lemna minor. Infrared thermography was applied for the different systems analysis, ...
