What is Radon Gas Mitigation?
Radon gas is a radioactive gas that naturally forms when radioactive metals such as thorium, radium, or uranium break down underground.
What Causes Landfills to Emit Methane and What Can We Do About It?
Decomposing organic matter deep within landfills emits literal tons of methane gas into the atmosphere each year. Using landfill methane capture programs, up to 90% of gas emissions can be redirected and used for fuel, electricity, or industrial applications.
What Is Remediation Contracting?
Remediation Contracting generally refers to a broad range of contracting services related to cleanup of contaminated or impacted sites.
Guide To Vapor Mitigation Systems
We often think of the foundation of a building as being absolutely solid. While this is the ultimate goal, it is not often true. Buildings can sometimes be faced with a phenomenon known as vapor intrusion. Contaminated groundwater or soil can emit dangerous gasses that find their way up and into structures.
Everything You Need To Know About Methane Mitigation Systems
An important factor to consider when building in Los Angeles is the presence of the natural gas methane in the soil.
Methane Mitigation: What Does It All Come Down To For Construction?
Passive vapor barrier mitigation systems generally involve two main components: the sub-slab ventilation system, and the actual membrane engineered to block vapors from passing through.
Water Crisis in California: Discussion
Check out this article I wrote in the LA Times local edition about our water shortage and what we can do about it.
Public Transit in LA
This article I wrote was published recently in LA Times local papers. It doesn’t pertain to geology directly, but certainly worth a look.
Earthquake Fault Studies
Anyone who has lived in southern California long enough knows that this is fault country, and if you are a property owner you have an obligation to yourself to safeguard your property against damage from earthquakes. Earthquake prediction science is as yet not developed enough to know when one will strike.
Private Sewage Disposal Systems
Septic systems have a long history. For developers in the early days, it was cheaper and faster to install septic systems than to install public sewers. Starting in the late 1940s and into the 1960s, the widespread use of septic systems for sewage disposal, with little to no governmental regulation, contributed significant pollution and environmental problems to groundwater, slope instability, and degradation of soils.
