Methane Testing and Soil Gas Survey
Methane testing is a process which examines the subsurface for combustible soil gas. The procedure includes drilling, constructing underground probes, and repetitive sampling.
Methane is a colorless and odorless gas that can move through soil. Consequently, methane gas accumulates inside buildings overtime. This hazard typically relates to historical oil fields and landfills. For this reason, a methane test is required for all construction projects in a Methane Zone or Buffer Zone.
Per the results of a methane test, a mitigation system will be required. Geo Forward is a preferred provider of methane soil gas testing and mitigation design services.
Methane Testing in Special Zones
Historical oil fields, storage ponds and oil wells are the main sources of natural gas in soil. Additionally, landfills cause methane gas build-up in soil. Awareness on the hazards of natural gas rises from a series of explosions in Los Angeles. Since the 1980s, the Los Angeles Department of Building and Safety (LADBS) and other local agencies require testing and mitigation in these special zones.
Los Angeles Methane Buffer Zone
The City of Los Angeles established high-risk boundaries which define a Methane Zone or a Buffer Zone. Accordingly, these zones require soil inspections when undergoing development. Similarly, other local agencies apply mitigation standards. Mitigation requirements can be reviewed in Ordinance No. 175790 and Ordinance No. 180619.
Geo Forward is a licensed soil testing agency and mitigation consultant for the City of Los Angeles Department of Building and Safety. LADBS Methane Test services include locating hazards, drilling, constructing probes, sampling, reporting, consulting and more. Furthermore, Geo Forward assessments are fast and include an open dialog with clients.
Unincorporated cities under the jurisdiction of the Los Angeles County Methane Mitigation Unit also require soil gas testing. Please Click Here to view the County of Los Angeles Building Code.
Huntington Beach & Orange County
The City of Huntington Beach and other Orange County agencies require methane soil tests. Additionally, some portions of Yorba Linda are known hazard zones. Furthermore, the City of Santa Fe Springs in Los Angeles County also regulates high methane soil gas testing zones.
Geo Forward designs Methane Mitigation Plans which consider site-specific methane soil test data. Our experts design systems that meet LADBS site design requirements at a feasible cost for construction. Click here to learn more about Mitigation Design Options.
