Firefighting foams are a primary source of PFAS pollution.

This is the second article in a three-part series considering the challenges PFAS (per or poly fluorinated alkyl substances) present to the environment and potential options for overcoming such challenges. Part I of this series can be found here. The thermal stability and chemical inertness of perfluoroalkyl substances (PFAS) has led to these man-made chemical …

This is the first article in a three-part series considering the challenges PFAS (per or poly fluorinated alkyl substances) present to the environment and potential options for overcoming such challenges. In centuries past, chemistry was a dangerous profession. Carl Wilhelm Scheele (1742-1786) was dubbed “hard luck Scheele” by Isaac Asimov, because others often got credit …

Stormwater stream flowing out underground tunnel into river.

Why should we care about stormwater? Have you ever wondered what a mass extinction event might look like? Certainly, such events are well documented in the geologic record, involving gamma ray bursts, asteroids and comets, and perhaps the biggest killer so far, volcanism. Volcanism is commonly accepted as the cause of the Permian-Triassic extinction, also known as …

Proper dry scrubbing technology selection requires a detailed understanding of the application and related technologies.

Operators of combustion equipment are tasked with removing acid gases and particulate. Traditionally, wet scrubbers were used to absorb the gases, but the problem with wet scrubbers is the resultant water pollution. The exception is the limestone gypsum process, which produces wallboard quality gypsum. However, even this process has some water pollution due to washing …
