Sampling for trace metals in groundwaters, surface waters, leachates and process waters is one of the most common field techniques utilized across the environmental industry globally. There are several practices used in different regions and this EnviroMail discusses changes at ALS Canada in support of global best practice. This is the first of two EnviroMails that will provide background information and technical guidance on trace metal preservation and sampling, along with changes being introduced by ALS to help maximize quality, safety, and efficiency in the field. The second EnviroMail due for release next month will look at the importance of field filtration and the impacts this can have on data quality. Read More

There are hundreds of chemicals that can be classed as PFAS (Per and poly-fluorinated Alkyl Substances). Accredited laboratories typically determine approximately 30 of these specific chemicals. In many fire-fighting foams and other products containing PFAS, the bulk of these chemicals may be tied up in more complex molecules including polymeric compounds. Routine laboratory analysis, for the most part, includes PFAS as carboxylic and sulfonic acids and may also include one or more sulfonamides [1,2]. Read More
