Tungsten (represented on the periodic table as “W”) is a naturally occurring element that exists in the environment as minerals with the two most common minerals being Wolframite and Scheelite. Due to tungsten's unique properties, such as its remarkable tensile strength, conductivity, and melting point, it can be found in [...]
What are the nuances of the Resource Conservation and Recovery Act (RCRA)? It was approved by Congress on October 21, 1976, or about six years after EPA was formed. RCRA was an amendment to the Solid Waste Disposal Act 0f 1965, note five years before EPA was formed. RCRA was [...]
What comes to mind when you hear the term “sustainability?” Chances are your first thoughts are environmentalism, recycling, or renewable energy. While environmental topics like these are certainly important pieces of sustainability, they represent only a fraction of the complete sustainability picture. Join our webinar as we dispel common misconceptions [...]
There are many available different ways to obtain closure for environmentally impacted Sites. One of the quickest and proven methods, albeit perceived to be an expensive option, is thermal remediation. Electric Resistance Heating (ERH) is a method of remediation that was used at a Site in central Indiana in an [...]
It seems like just yesterday we were discussing updates to the 2013 Phase I Environmental Site Assessments (ESA) standard and yet here we are again with another revision to the standard that was recently approved by the EPA with an effective date of February 13, 2023. Why another revision? According [...]
Biological wastewater treatment employs microscopic organisms to breakdown waste and ensure clean effluent. These “bugs” are often referred to as the hardest working employees at wastewater treatment facilities. As microscopes become a standard tool in wastewater facilities and laboratories, operators have an opportunity to add a powerful tool to their [...]
Before installing any new equipment or modifying existing equipment in Pennsylvania, make sure you do your homework and understand the basic requirements. An air permit just might be needed for that new installation. This webinar will discuss how to know when an air permit is necessary, the different types of [...]
There are several factors that should be taken into consideration when evaluating recognized environmental conditions (RECs) during a Phase I Environmental Site Assessment (ESA). RECs are found on industrial and commercial properties for a variety of causes. This webinar will dive into what is evaluated to determine RECs, their potential [...]
Chemical reduction and oxidation are common remediation technologies used for a variety of contaminants in soil and groundwater. Pilot studies play a vital role in providing information necessary for full-scale remediation. This webinar will detail a case study of the remediation process from pilot test to full-scale design and implementation [...]
On March 29, 2023, the U.S. EPA published the proposed PFAS Drinking Water Regulations in the Federal Register. This proposed rule for Per- and Polyfluoroalkyl Substances (PFAS) includes Maximum Contaminant Levels (MCLs) of 4.0 ng/L for two PFAS constituents (PFOA and PFOS), and an MCL using a Hazard Index of [...]
