A train pulling 72 tank cars, laden with oil from hydraulic fracturing (fracking) in North Dakota, derailed and exploded in Lac-Mégantic, Québec on July 6, 2013, killing 50 people. Such accidents are a product of the boom in “pipeline on rails” methods of shipping oil. In 2009, a mere 500 tank cars of oil were transported by rail in Canada. For 2013, this was projected to be as high as 140,000 tank cars.

Abstract

Now, more than ever, the environment is one of the key issues concerning everyone globally, from politicians and scientists, to the general public. Responsible businesses must acknowledge the importance of protecting our ecosystems, and prosecutions for polluting the environment can not only lead to expensive fines, but can also result in irreparable damage to an organisation’s public image.

Introduction

One of the very first steps in any drinking and clean Water Treatment Plant (WTP) is the abstraction of water from a water source. Typical water sources used for these applications include boreholes, springs, rivers, reservoirs, lakes and the sea. Each water source presents a specific set of challenges and characteristics yet they may all be subject to anthropogenic pollution events, such as oil and chemical spills from roads, industry, household and e

Abstract

Awareness of risks associated with THMs in drinking water has increased steadily over the course of the last three decades. A number of technologies have been developed to provide Water Treatment Plants with the tools to perform on-line monitoring of THMs in drinking water. This article describes the state of art of on-line THM analysers and focuses on the e-nose based system. Data from real-life installations are presented with a detailed explanation of t

PROBLEM

The local health authority had warned that the THM level in the water supplied to households in the region was above or near the limit imposed by the law. For this reason, the local WTP was asked to install an on-line THM monitoring system and implement improved control of the process.
