A new ASTM International standard examines how the process of ebullition can cause the movement of contaminants at sediment sites. ASTM International member Tripp Fischer explains that ebullition is the process of gas (primarily methane) generation in sediments where the quantity of gas generated is sufficient for gas bubbles to nucleate, grow, fracture the sediment, and then escape into the…

A new ASTM International standard will help laboratories to better determine the presence of polyfluoroalkyl substances (PFAS) in environmental samples. ASTM’s committee on environmental assessment, risk management and corrective action ( E50 ) developed the new standard. PFAS are a large, complex group of compounds found in water, air, fish, and soil throughout the world. Additionally, some…

New standard practices and specifications developed by ASTM International’s plastic piping systems committee ( F17 ) establish requirements and test methods for polyamide-12 (PA12) materials, pipe, and fittings. PA12 line pipe is made using polyamide-12, a specialty type of nylon plastic with exceptional strength and durability compared to other plastics used in pressure piping systems. The new…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Robert Morgan, tel +1.610.832.9732; rmorgan@astm.org Release #11271 ###

A proposed ASTM International standard provides guidance on the management of investigation-derived waste (IDW) from sites that may be impacted by perfluoralkyl substances (PFAS). The committee on environmental assessment, risk management, and corrective action (E50) is developing the standard. PFAS are chemicals often found in products including household items, outdoor gear, nonstick cookware…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Molly Lynyak, tel +1.610.832.9743; mlynyak@astm.org Release #11047 ###
