Phase I Environmental Site Assessment Process The Phase I Environmental Site Assessment process comprises a rigorous review of a property’s history, along with a physical inspection of the current conditions. And the end result is a lengthy report that follows regulation standards. For the convenience of Clients, environmental consultants usually provide executive summaries at the…
What is the Methane Mitigation Process? The methane mitigation process entails eliminating the risk of an explosive event at a building, as a result of hazardous soil vapor intrusion. Vapor intrusion is the natural process by which underground gasses migrate upwards and into buildings. So in the case of structures built atop contaminated soils, the…

He’s also known as an honorary public figure for advocating the conservation of wildlife from the mid-1800s to the early 1900s. To many, he was a self-mastered glaciologist,…
LADBS Methane Soil Test Cost & Price An LADBS Methane Soil Test varies depending on property conditions and development plans. A methane test price ranges between $2,300 and $7,000. Updated January 17, 2024. Site-Specific Scope of Work Site-specific details and plans can change the scope of work and LADBS Methane Soil Test cost. Thus, a…
PCBs Contamination in Killer Whales and Orca Pollution PCBs contamination in killer whales and orca pollution is an increasing concern in the environmental science community. Recent studies indicate hazardous levels of industrial chemicals exist in the bodies of orcas and other marine mammals, worldwide. In fact, toxicologists now hypothesize that rising concentrations of carcinogens like…
Phase 2 Environmental Screening Level Phase 2 Environmental Screening Level Numbers are comparative concentrations of chemicals in soil or soil-gas, which represent a threshold for human health concern. In a Phase 2 Environmental Site Assessment, these numbers are tools to compare directly with the contaminant detection on site. As a result, a practical risk assessment…
Landfill Methane Gas Testing Landfill methane gas testing is the process by which professional geologists and engineers determine the concentration of landfill gas between soil grains underground. Usually, this is a requirement by environmental regulatory agencies and building departments for the protection of public health. In fact, quarterly landfill gas testing is a common regulation…

Historical Recognized Environmental Condition (HREC) The term Historical Recognized Environmental Condition (HREC) refers to a past release that doesn’t pose a present land-use restriction, nor does it warrant recommendations for clean-up. The HREC is one of the various conditions of a Phase 1 Environmental Site Assessment. The definition derives from publications by the American Society…
Definition of Recognized Environmental Condition (REC) What is a Recognized Environmental Condition (REC)? A simplified definition of a recognized environmental condition (REC) is any occurrence whereby: 1). actual pollution of the environment is occurring; 2). the threat of pollution of the environment occurs; or 3). there is a preponderance of evidence suggesting possible pollution of…
Controlled Recognized Environmental Condition (CREC) CREC stands for Controlled Recognized Environmental Condition. This terminology derives from a Phase 1 Environmental Site Assessment and represents one of the few categories of environmental concerns. A CREC is a release that has potentially achieved corrective action, but where contaminants still may remain, and where engineering controls or activity use…
