Great Lakes Monitoring

2 years ago

The Great Lakes are the largest available freshwater resource in the world. The Great Lakes region is heavily populated and was the largest centre of industry in North America for much of the 20th century. Unfortunately, many of the activities occurred during time periods of insufficient environmental knowledge and the Great Lakes were not protected from potentially devastating environmental effects. As a result, testing for legacy Persistent Organic Pollutants (POPs) remains of key importance. Stakeholders in the region have been successful in reducing many environmental contaminant issues but continue to deal with new issues on a regular basis. Consequently, the Great Lakes region remains the largest area of environmental…

Aqueous Film-Forming Foam (AFFF) Assessments

2 years ago

Aqueous film-forming foams (AFFF) are perfluorinated compound (PFC)-containing chemicals, which have been in use since the 1960s for hydrocarbon fire suppression. Historically, AFFF compounds most frequently associated with contamination at AFFF sites include:

Perfluoroalkyl acid (PFAA) -- Carboxylates and sulfonates, which could be part of AFFF formulations or breakdown products from larger AFFF compounds
Perfluorinated carboxylates (PFCAs) -- Fluorotelomer sulfonate (FTS) based with degradation products that produce FTS and C7 or shorter chain perfluorinated carboxylates (PFCAs)
Perfluoroalkyl sulfonates (PFSAs)-- Perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), perfluorobutane sulfonate (PFBS)  are examples of compounds in this class

When groundwater contamination crosses AFFF site boundaries, it may require analysis of the contamination of the surrounding environment and…

Oil and Gas Applications

2 years ago

The petroleum industry is experiencing notable change and long-term economic development -- Significant production expansions from the oil sands, tight (shale) oil and gas projects, offshore sources, alongside other projects to bring petroleum production to new markets are currently in process. These changes are driving regulatory and societal requirements for a better understanding of the potential environmental impact. Enhanced scientific understanding of the pre-development baseline and subsequent monitoring of change on a regional basis ensures effective and responsible environmental management of this development. Typical requirements include:

Water, soil/sediment, and biota regional baseline assessment prior to development to establish pre-development conditions
Long-term monitoring to measure changes as development and production…

Eco-Tox

2 years ago

Ecotoxicology integrates toxicology and ecology to study of the effects of toxic chemicals found in the water, soil, and air on biological organisms and their populations, communities and terrestrial, freshwater and marine ecosystems. Ecotoxicologist have leveraged contaminant analysis to focus on predicting the effects of pollution to help identify the most efficient and effective action to prevent or remediate any detrimental effect, or restore ecosystem services and functions. Recent advances in metabolic fingerprinting/metabolomics offer the opportunity to observe early and/or sensitive responses to contaminant insults. Metabolomics is increasingly used in ecotoxicology to connect contaminant exposure of sentinel species to early…

Forensic & Source Fingerprinting

2 years ago

Analytical methods may be applied to forensic or technical problem solving projects in a wide variety of situations, including natural resource damage sourcing. Common applications include:

Attribution of source of hydrocarbons through multiple lines of evidence (PAHs + alkylated PAHs, Alkanes, speciated Naphthenic acids)
Identification of the behaviour of wastewater contaminants by using PPCP and fecal sterols to identify areas under the influence of these processes. Results from these studies are often used to evaluate the need or efficacy of major capital projects in this area
Identification of PCB sources through PCB congener profiles
Identification and profiling of contaminants (and potential effects) by humans or…

High-Volume and Passive Sampling Support

3 years ago

There are two broad categories of sampling technologies, each meeting a specific set of needs in the field:

High Volume Sampling - For many regional monitoring or TMDL programs, there is a need to detect low concentrations of contaminants by using large volumes of water concentrated on sampling media.  Reliable data, from both dissolved and particulate bound phase, are necessary to support mass balance models.

Passive Sampling - As understanding of contaminants evolve, contaminated site investigations and responsible parties projects increasingly involve understanding the specific amount of contaminant available for uptake to the organism, represented by the dissolved fraction, as the particulate phase is not available.

Exposomics – Biomonitoring, Epidemiology and Litigation/Settlement Studies

3 years ago

There is an ongoing demand by industry, agencies, academics and consultancies to assess legacy Persistent Organic Pollutants (POPs) in humans, leading to studies on exposure, toxicity, and mechanisms, and epidemiology.  From this focus on exposure science and epidemiology, there is a growing interest in contaminants of emerging concern (CECs) and a desire to measure CECs arising from consumer products as part of biomonitoring efforts. These CECs contribute to body burden and have been linked to many health effects including endocrine disruption, but have not been adequately characterized due to a paucity of accurate/precise methods designed for medium/large-scale studies.  Litigation and settlement…

Total Maximum Daily Load and Regional Monitoring Programs

3 years ago

There is a widespread need to monitor the environment on a regional level (as opposed to points of discharge or specific sites), which may include benchmarking the current environmental state of a region or addressing existing impairment issues throughout a region, or both. The work may fall into TMDL type programs where assessment of impairment or elimination of impairment is required. Specific Federal protocols, such as those described in TMDLs or 303D regulations of the clean water act, or protocols developed to address regional needs from different regulatory authorities govern the scope of work. Generally, the groups that conduct this…
