WHAT ARE PFAS CHEMICALS? Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS and GenX chemicals. Since the 1940s, PFAS have been manufactured and used in a variety of industries around the globe, including in the United States. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both are very persistent in the environment and in the human body. Exposure to certain PFAS can lead to adverse human health effects.

Crude oil undergoes a process called fractional distillation in the refinery plants. Crude oil is being heaten to crack down to shorter hydrocarbon chain under different temperature. The major by products are refinery gas, petrol, naphtha, kerosene, diesel, lubricating oil, fuel oil and bitumen.

In Hydrocarbon storage there is a high likelihood of water contamination, this water gathers underneath the hydrocarbon cargo and can cause accelerated corrosion of the tank, requiring the lining of the base and 1 meter up the wall. For linings to perform as intended they need to have a chemical and mechanical bond to the substrate, which requires the steel to be clean, reactive and rough, often achieved through abrasive blasting.

We look into whether hazardous waste sites cause health risks. A hazardous waste site can be any place where chemicals have gotten into the air, water and soil. Former landfills and industrial plants, even areas where crops have been grown, can be hazardous waste sites.

The Centers for Disease Control and Prevention (CDC) oversees the U.S. chemical weapons elimination program. We've worked for over 30 years to keep Americans safe from dangerous chemicals in warfare materials by monitoring the process for safely destroying them and making sure workers and nearby communities stay safe and healthy.
