We at MJM Environmental can perform a large array of air emission sampling test parameters to industry and environmental authority standards. Our accreditation (ISO/IEC 17025, accreditation number 20692) covers a range of industrial air emission sampling test parameters. To view the scope of our accreditation, please click here to access the NATA website. Our methods are listed and current at our ...
‘You can’t manage what you can’t measure.’ Although a familiar statement to many environmental managers, site-generated air quality, noise, water quality, odour, dust and vibration emissions have always been a notoriously difficult challenge. For many years environmental monitoring was a repetitive and cumbersome task. The process of collecting real numbers to review ...
Customer: Wastewater treatment Localisation: United States of America Installation: Close to the ponds and property line for the neighbourhood Function: Measuring odour emissions (H2S) Location Background This wasterwater and stormwater treatment plant is one of the largest in the world. It treats an average of 1.3 billion gallons (6 million m3) of wastewater each day- 500 billions gallons (2.2 ...

Abstract Because of complaints related to odors emissions from the large “Seine Aval” wastewater treatment plant (2 000 000 cubic meters/day) located near Paris, an extensive measurement programme has been performed, both by olfactometric and physicochemical techniques, in order to characterize the emissions from each step of the water- and sludge treatment ...
Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of ...
Odour impact assessment has become an important environmental issue. Different approaches can be used in order to evaluate the odour impact on receptors, and therefore to regulate it. Among the different possible regulation approaches, the use of dispersion modelling is suggested or required by several national or regional legislations. The wide diffusion of this approach is probably due to the ...
Gaussian and Lagrangian model runs are evaluated in comparison to field data from the Odour Release and Odour Dispersion (OROD) project and to wind tunnel data from the Mock Urban Setting Test (MUST). Different statistical metrics are discussed. The results illustrate once again that a good model performance is strongly dependent on the model input (e.g., terrain data, roughness length). ...
We present a review of regulatory atmospheric dispersion models and their application to environmental impact assessment (EIA) in Finland. The following regulatory models are available: the urban dispersion modeling system, models for dispersion of vehicular pollution, the air ...
The three main components of a study into the behaviour of material emitted into the atmosphere, i.e. emissions, dispersion and impacts, are discussed in the context of predicting odour nuisance. In particular, the importance of the effects of buildings on dispersion, and the significance of short averaging times are considered. Finally, an approach is suggested for modelling odour nuisance ...
