Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
The typical regulatory limit of methane is 500 parts per million (ppm) by volume (in California, AB 32 may push this limit down to 200 ppm). In the UK the limit for a final landfill cap is 1 × 10 −3 milligrams per square metre per second, and for a temporary cap it is 1 × 10 −1 mg/m 2 /s (as measured using the Environment Agency's ...
The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay. EPA and other ...
As landfill operators struggle to control the chemical reaction, they acknowledge that the amount of contaminated water leaking from the facility has increased from about 20,000 gallons a day to ...
The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations. [1] These locations are known as Superfund sites and are placed on the National Priorities List (NPL).
The US Environmental Protection Agency issued new rules on Tuesday to protect neighborhoods near more than 200 manufacturing facilities that release airborne toxins such as ethylene oxide ...
The California Department of Resources Recycling and Recovery (also known as CalRecycle) is a branch of the California Environmental Protection Agency that oversees the state's waste management, recycling, and waste reduction programs. CalRecycle was established in 2010 to replace the California Integrated Waste Management Board.
OEHHA has no regulatory authority but remains the risk assessment and scientific arm of Cal/EPA and provides health-protective scientific guidance for Cal/EPA. Additionally, OEHHA is the lead agency for Proposition 65 implementation, a ballot measure approved in 1986, titled The Safe Drinking Water and Toxic Enforcement Act of 1986 .
