Laser Gas Detection TDLS Technology

Axetris uses proprietary technology-enhanced TDLS for gas detection. A 0.05 nm narrow bandwidth diode laser beam is used to scan across an absorption band of the target gas, thus performing a high-resolution near infrared absorption measurement. Laser gas detection, based on Tunable Diode Laser Spectroscopy or TDLS, provides a valid solution to many challenges in environmental gas ...

Monitoring contamination without excessive cost

Environmental monitoring should be undertaken with the best available technology within reasonable cost constraints (i.e. BATNEEC). However, the best technology is often the most expensive, so instrument rental is increasingly the favoured option. James Carlyle, General Manager at specialist instrument hire company Ashtead Technology Rentals, explains. The requirement for environmental ...

EPA to Require Monitoring for Unregulated Contaminants

(Washington, D.C.) Approximately 4,000 public water systems will monitor drinking water for up to 25 unregulated chemicals to inform EPA about the frequency and levels at which these contaminants are found in drinking water systems across the United States. The information will help determine whether regulations are needed to protect public health. This is the second scheduled review under the ...

Land Contamination

Land Contamination Identified: Contaminated land is a constant battle for developers looking to build houses / industrial sites or purpose built facilities. Contamination simply means an unacceptable risk to human health or the environment and therefore remediation or site clean up is required. Identifying contamination requires assessment, measurement and remediation. The primary contaminants ...

Monitoring heavy metal contamination in the German Wadden Sea

Human activities, including industrial development along coastal areas, risk polluting the marine environment with heavy metals which can harm human health and aquatic life. A recent study has found elevated levels of metal pollution in the Jade area of the German Wadden Sea, but concludes that metal contamination of the sediments would not be expected to have harmful effects on the marine ...

EPA Determination on 11 Contaminants

The U.S. EPA has made a preliminary determination not to regulate 11 contaminants on the second drinking water contaminant candidate list (CCL). The agency?s preliminary regulatory determination, based on an extensive review of health effects and occurrence data, concludes that the specific contaminants do not occur at levels of public health concern in public water systems. 'We are confident ...

Contaminants in US groundwater

According to a new study by the USGS, more than 20% of untreated water samples from 932 public wells across the US contained at least one contaminant at levels of potential health concern. About one-third of the US population receive their drinking water from such a system. The USGS study (Contaminants in Groundwater used for ...

Shedding a light on contaminants

Name a current environmental challenge. Global climate change? Loss of endangered species? What about soil contamination? Soil pollution rarely makes headlines, though it is a prevalent global issue. According to the European Environment Agency, 39 member states in Europe had over 2.5 million contaminated soil sites in 2011. Sharon O’Rourke, researcher at University ...

PFOS not widespread contaminant of drinking water

Although limited data exists on perfluorinated chemicals in water, a recent study published in CIWEM’s Water and Environment Journal has found that perfluorooctane sulphonate (PFOS) is not a widespread contaminant of drinking water in England. PFOS has a number of industrial and commercial uses, including as a surfactant for fire-fighting foam, a mist suppressant for metal-plating baths and ...

Drinking water wells vulnerable to contamination

New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States ...
