  • On-site analysis of cannabis potency using Infrared spectroscopy

    Cannabis is increasingly being recognised for its therapeutic value. This has led to a reduction in its regulation, and even its legalisation, by many different governments. As cannabis production becomes legalised and regulated it is important that manufacturers can assess the chemical content and potency of their plants. The value of cannabis in the control of pain, spasm and a range of ...

  • River Water Quality indicator for sustainable development - 2008 results

    The river water quality indicator is one of the 68 indicators of the Government’s Sustainable Development Strategy. It separately measures biological and chemical river water quality on an annual basis and the indicator for each represents the proportion of river water, in terms of river length, which is considered to be of “good” quality. Headline results In England: 72 per cent of river ...

  • Measurement of lime levels in drinking water & wastewater

    As lime is a product derived from the Earth, it is fitting that many of its uses also benefit the Earth. In fact, the second leading use of lime is in environmental applications, including drinking water and wastewater. OPTIFLEX is widely used to indicate lime levels in storage silos. It usually replaces non-reliable ultrasonic or electromechanical systems that are expensive to maintain. Lime ...


  • Unsustainable water consumption contributes to sea level rise

    The global sea level is rising, yet only part of that rise can be attributed to the effects of climate change. New research has calculated that human impacts on terrestrial water storage make up around 42% of total sea level rise, in particular, the extraction of groundwater that eventually makes its way to the ocean. Tidal measurements have revealed that the global sea level rose by 1.8mm per ...

  • New indicator proposed for assessing treated wastewater quality

    The chemical, physical and microbiological characteristics of effluents from wastewater treatment plants are regulated by national and EU law for discharge into surface waters or reuse, but a wide variety of treatment options exist and monitoring all pollutants may be expensive. A new study from Italy proposes a new Wastewater Polishing Index (WWPI) to help decision makers and environmental ...

  • Early signs indicate New Mexico water wells unharmed by gold mine toxic release

    While the August 5 toxic waste release from Colorado’s Gold King Mine into Colorado’s Animas River presents the potential for contamination of groundwater used by drinking water wells, early indications are that New Mexico wells may not be affected, the National Ground Water Association said today. “Continued vigilance in monitoring groundwater supplies along the river remain ...

  • Radar water level sensor undergoes river thames trial

    Environment Agency hydrologists have recently trialled a new radar water level sensor at a site by Molesey Lock on the River Thames near Hampton Court Palace. The sensor was installed during October 2008 and initial results indicate that significant time and cost savings are possible with the new technology. Water level measurements are taken at Molesey Lock for onward transmission to the ...

  • Drinking water in Gaza Strip contaminated with high levels of nitrate

    Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. 90 per cent of their water samples were found to contain nitrate concentrations that were between two and eight times higher than the limit recommended by the World Health Organization (WHO), say the researchers from ...

  • At the highest international level: A top performance from the waste and waste-water industry

    The task of dealing with waste is changing rapidly, with the focus moving away from simple disposal and towards exploiting all recoverable substances. Europe, and Germany in particular, has taken on a leading role in this regard. This is demonstrated firstly by the high levels of expenditure on environmental protection, and secondly by the wealth of highly innovative technological developments. ...

  • Water levels dropping in some major rivers as global climate changes

    Rivers in some of the world’s most populous regions are losing water, according to a new comprehensive study of global stream flow. The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate change. The process could potentially threaten future supplies of food and water. The results will be ...

  • EPA Releases Updated Environmental and Public Health Indicators in Online Database

  • Nutrient levels on the decline in many Estonian rivers

    A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites. High levels of nutrients, such as nitrogen and phosphorus, ...

  • High Polonium-210 Levels Found in Nevada Wells
