The objective of environmental groundwater sampling is to collect a water sample that represents the composition of all mobile groundwater (GW) constituents in an aquifer, which may include both dissolved phase and colloidal materials that can migrate through the aquifer. Read More

Further to the earlier content published below, due to broader recent awareness that delayed filtration can cause severe negative bias of dissolved metals, BC ENV (the BC Ministry of Environment & Climate Change Strategy) has issued a requirement, effective May 1, 2020, for field filtration of all water samples that will be tested for dissolved metals (including mercury).

Each year, traditional environmental monitoring programs in Canada require the sacrifice of many thousands of fish that are killed and filleted prior to chemical analysis of muscle tissue for metallic contaminants. Read More

ALS Environmental Canada is introducing a new Organochlorine Pesticide (OCP) test method for waters, using state-of-the-art GC/MS/MS triple quadrupole instrumentation to achieve trace level detection limits with near-zero chance of false positives, using 100 mL sample bottles. This new method raises the bar for data quality over traditional test methods that use either single quadrupole GC/MS or GC/ECD (Electron Capture Detection). Read More

The measurement of total arsenic concentrations is generally adequate for environmental compliance monitoring, but knowledge of discrete inorganic and organic arsenic species concentrations is crucial to understanding true toxicity and health risks to humans and aquatic or terrestrial organisms. Humans are exposed to arsenic in many ways, including occupational exposure (e.g. smelting, mining), drinking water, and food sources, but the toxicity of different arsenic species and sources varies greatly.

Selenium (Se) is an essential nutrient for humans and many microorganisms, as a component of selenoproteins such as selenocysteine (the 21st amino acid) and selenomethionine. The recommended dietary allowance for selenium is 55 μg/day, but excessive levels can cause human health problems (selenosis). Read More

At ALS we know that optimizing time spent in the field is important to our clients, as is the reduction of manual handling.  Read More

Failing to evaluate the market for certification service providers could be a costly mistake for your company, causing you to spend too much for certification while getting inadequate service. Read More

New benefits to the efficiency of soil-gas sample collection for Volatile Organic Compounds (VOCs) by the Thermal Desorption (TD) method have become possible through recent validated innovations.  Read More

ALS Environmental has made significant advances in sample size reduction, leading the industry towards safer and more sustainable practices. Lower water sample volume requirements can significantly reduce sampling times; and smaller, lighter coolers reduce the risk of strain injuries in the field. Read More
