An asbestos study published in 1946 in the Journal of Industrial Hygiene and Toxicology that aimed to measure the safety of using asbestos to build warships is considered for retraction. Critics find issue with the analysis adopted sampling method saying that it wasn’t the standard used at the time.

The controversial study was presented as evidence before the US Supreme Court as recently as 2018

EPA Adds Select PFAS Chemicals to CERCLA Hazardous Substances List

The United States Environmental Protection Agency (US EPA) has designated two widely used polyfluoroalkyl substance (PFAS) chemicals as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund. The chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are part of a phase-out manufacturing approach to reduce the production due to their potential health and environmental impacts. Two major processes, electrochemical fluorination (ECF) and fluorotelomerization, have been (and are) used to manufacture PFAS substances that contain perfluoroalkyl chains. PFAS are used in many industrial and consumer applications that may affect the environment or receptors by various mechanisms and to various degrees. Some uses of PFAS are building and construction material, cable and wiring, paper products and packaging, the semiconductor industry, and textiles, leather and apparel.

Earlier this month, the Presidential Administration issued the first-ever, national and legally enforceable drinking water standard for five individual PFAS chemicals and limits for mixtures of any two or more of four PFAS chemicals, allowing the public water systems three years to complete their initial monitoring for these chemicals and to implements mitigation measures to reduce PFAS in drinking water within five years. (see full story here)

In addition to the announcement, US EPA issued a memorandum providing direction about its enforcement discretion and how it will hold responsible entities who significantly contribute to PFAS contamination to the environment.

Waterstone professional personnel are highly trained and knowledgeable in the steps needed to determine if PFAS pollution is affecting your project. We can design and implement a sampling strategy to establish baseline values and delineate any onsite plumes. Call us today or visit our website to arrange for a free consultation.

The Environmental Protection Agency (EPA) yesterday banned the last form of asbestos still imported into the United States. Asbestos is fire-resistant and durable and has long been used in building materials like insulation. Asbestos exposure is linked to lung and other forms of cancer, killing an estimated 40,000 Americans each year. It can be challenging for the body to clear and when inhaled, can cling to the lining of the lungs, causing a form of cancer known as mesothelioma.

While asbestos manufacturing has declined since the 1970s, one of its six forms—chrysotile asbestos—is still being imported into the US...until yesterday! Actually, the EPA has set compliance deadlines to transition away from the use of chrysotile asbestos in all applications, which are as soon as is practicable for each use while also providing a reasonable transition period, which the law requires.
