Optical gas imaging (OGI) has traditionally been a qualitative technology. Recent advancements in the technology are moving OGI towards quantitative methods. New quantitative features in the FLIR GF series cameras and QL320 tablet provide a much more efficient user experience and remove much of the uncertainty related to OGI surveys and resulting quantification of emissions. FLIR's new Q-mode captures radiometric OGI data, along with meta data provided by the user, into a single file forma...

Methane escape from natural gas distribution systems results not only in global warming, but also in economic loss. An estimate from the Boston region implies a financial damage of $90 million as about 15 billion cubic feet of natural gas escape from the distribution system annually (McKain et al., 2015). Mobile real-time measurements of methane in ambient air offer a fast and effective method to identify and quantify local methane emissions in urban areas. Between February and April, 2018...

The quality of wastewater generated from industrial operations and municipalities is highly regulated and closely monitored. Traditional “oxygen demand” methods of determining wastewater quality can be time-consuming, costly, and less accurate. Total Organic Carbon (TOC) analysis offers a highly sensitive, non-specific measurement of organics present in a sample. Plants monitoring for TOC are better equipped to adjust their processes, protect capital equipment and meet effluent regulation...

The measurement of compounds in air using passive (diffusive) monitoring is widely recognized especially for long term (averaged) information on air quality.  The promulgation of EPA method 325 by the US Environmental Protection Agency (EPA) validates this sampling technique.  This method is currently used in the investigation of compounds in air at the fenceline of selected industrial locations.   During development, EPA Method 325 (passive sampling) has been field tested including int...

Current spot checks are no longer satisfactory to avoid the potential for high-level contamination of rivers or estuaries from industrial waste. Governing environmental bodies can impose heavy fines on companies that routinely exceed the set limits, and even reserve the right to shut down the liable plant. This produces a requirement for online monitoring of multiple outlet streams from the plant, before and after potential dilution points. Monitoring the river for contamination from other...

A significant population of the world lives within the fertile river valleys and is affected directly by the quality of water. Increased urbanization and industrialization has led to a degradation of water quality in recent decades due to contaminants from several sources - industrial, agricultural and anthropogenic. Traditional methods that include time consuming lab analysis from point measurements often lose out on event detection and fail to establish a complete picture of the health of t...

Measurement of Fats, Oils and Grease (FOG) in waste water is a crucial parameter in water quality control and environmental monitoring performed by water suppliers laboratories and environmental authorities. Traditionally this is carried out by passing a volume of water through a filter which collects both FOG and solid particulates; after drying the filter, the FOG is determined by Soxhlet analysis. However the Soxhlet method is a long and laborious process, requires skilled operators and th...

The persistence of organic pollutants, such as pharmaceuticals, within the environment is a growing area of research. Until the introduction of current EU Directives the impact of drug emission into the environment through wastewater treatment was largely unconfirmed and unrestricted. Compounds with high octanol-water partition coefficient (Kow), like many common pharmaceuticals, are not biodegraded during wastewater treatment and can bioaccumulate through adsorption to soils and sludge. Typi...

Acidic herbicides are used to control broad-leaved weeds. They are stable, water soluble, and with low binding to soil are found frequently in surface waters, often at concentrations above the EU Drinking Water Directive limit of 0.10 µg L−1. This presents a problem when such waters are abstracted for potable supplies. Understanding their sources, transport and fate in river catchments is important. We developed a new Chemcatcher® passive sampler, comprising a 3M Empore™ anion-exchange...
