  • Healthy Habits - Improving Wellbeing on a Work Schedule

    As we firmly embrace 2017 crashing into these strange new numbers head on, many of us will be facing the harsh reality of our New Year resolutions; perhaps – just perhaps – in many cases feeling like we’ve promised just a little more than we can deliver. Taking an educated guess, it’s safe to assume many people’s plans will consist of some effort to get back into ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Regulation of water service and efficient use of water

    This report highlights the need for policies targeted to sustainable use of water, which, at the same time, affect water service providers and the environment. Experience from several European countries can help us to identify efficient regulation mechanisms and the effect they could have on the Italian water sector. Some elements of United Kingdom regulation and some of the energy regulation in ...

  • Uncertainty in UK water regulation could hinder investment

    The stability and predictability of water company regulation in the UK by the Water Services Regulation Authority ("Ofwat"), which is mandated to ensure value for the end consumer, has been a major contributor to attracting private investment into the sector. Since privatisation in 1989, this stable regulatory framework has enabled sector companies to attract over £108 billion of ...

  • Frequency pressure regulation in water supply systems

    In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional ...

  • A look at some contaminants regulated in drinking water

    The U.S. Environmental Protection Agency regulates just over 90 contaminants in public drinking water systems. They include manmade chemicals as well as naturally occurring contaminants from rocks and soil. A look at some of the contaminants that fall under federal or state regulations: ARSENIC: Enters drinking water through eroding natural deposits in the ground or mining and other ...

  • Reducing the Economic Friction of Regulation

    Last month, we looked at two distinctly different bioenergy business models that are merging. Energy profit centers and waste cost-recovery facilities are learning the benefits of each other's business model. The resulting projects generate maximum revenue with lower production costs. The same kind of business model duality occurs in biomass energy regulation. There are more than two kinds of ...

  • EPA Clean Water Act: New Regulations re: `Waters of the United States`

    The Environmental Protection Agency (EPA) published a final rule defining the scope of waters protected under the Clean Water Act… The rule will ensure protection for the nation’s public health and aquatic resources, and increase CWA program predictability and consistency by clarifying the scope of ‘‘waters of the United States’’ protected under the ...

  • Decoupling dependence on natural water: reflexivity in the regulation and allocation of water in Israel

    Since 1999, Israel has secured a decoupling between the total water supplied and water derived from the natural environment through surface and groundwater. Between 2007 and 2010, this decoupling enabled a cut of over 20% in natural water use, while maintaining overall supply volumes despite drought. By 2009–2010, natural water supply had been reduced to the levels of the early ...

  • Gray Water Characteristics and Implications on Regulations for Sustainable Water Reuse

    Different types of gray water in terms of origin (from bathing, kitchen and laundry activities) and in terms of type of source (medium and low-income residential housing and a hotel) have been studied in Gaborone, Botswana during 2004, with respect to BOD5, TSS, TP, pH, fecal coliforms and conductivity. Results show an expected high variability. No statistically significant difference was ...

  • Opinion: Environmental regulation in the 21st century

    INTRODUCTION I start with a statement of the obvious. The aim of environmental regulation is to produce measurable improvements in the environment. But how much environmental regulation expresses the desired environmental outcome? How much, on the other hand, sets out the regulatory process? Not enough of the former, too much of the latter. That unremarkable statement of aim is at the ...


  • Nutrient Regulation on Streams: The Macrophyte Quandary

    ABSTRACTSince promulgation of the Clean Water Act in the 1970s and implementation of technology-based treatment requirements, such as secondary treatment for publicly owned treatment works, the nation’s water quality has improved dramatically. Current water quality concerns are no longer attributed to excessive loads of carbonaceous and nitrogenous biochemical oxygen demand. Rather, the largely ...

  • Oil Storage Requirements of the SPCC Regulations

    ABSTRACTThe SPCC regulations entail numerous requirements for the storage of oil. The intent of this paper is to summarize several of the complex requirements associated with oil storage at a facility subject to the SPCC regulations. INTRODUCTIONThe Spill Prevention, Control, and Countermeasure (SPCC) regulations are far reaching requirements promulgated by the ...

  • Maximizing the accuracy of field‐derived numeric nutrient criteria in water quality regulations

    High levels of the nutrients nitrogen and phosphorus can cause unhealthy biological or ecological conditions in surface waters, and prevent the attainment of their designated uses. Regulatory agencies are developing numeric criteria for these nutrients in an effort to ensure that the surface waters in their jurisdictions remain healthy and productive, and that water quality standards are met. ...

  • Can regulation improve the performance of government-controlled water utilities?

    This paper provides evidence on whether regulation can improve the performance of government-controlled water utilities. While other studies have examined whether private participation combined with regulation can improve the performance of government-controlled water utilities, there has been little research on whether regulation alone can improve performance.This paper examines five case ...
