Did you know that Los Angeles sits on top of the third largest oil field in the country? Did you know oil rigs are scattered covertly throughout the city, near schools, malls and even a in the middle of residential neighborhoods? And for every active oil well, there are ten or more wells that were abandoned sometime in the beginning to middle of the last century. Although the wells abandoned in the last few decades were abandoned using methods that are considered protective of human health and groundwater resources, wells abandoned prior to the 1980s’ are suspect.
The location and condition of abandoned wells typically remains unknown until a builder attempts to develop a building over or near one of these wells. In such cases developers and/or owners of said properties may be faced with uncertainties and adverse property conditions due to improper abandonment by the oil company based on current abandonment standards. Such adverse conditions may thwart development, create a hazardous situation, and ultimately adversely affect the monetary worth of the property.
Recently, Andersen Environmental was able to assist a developer locate and re-abandon several well located on a hillside property slated for development of affordable housing units and a community center near Downtown Los Angeles. Specific challenges overcome included terracing the site to accommodate the abandonment rigs, special handling of the oil impacted soil encountered in the area of the oil wells, and the condition of the oil wells which were up to 80 years old. In addition, the well casings were deteriorated and filled with debris (“junk”) left behind when the oil wells were originally abandoned. Nonetheless, the identified wells were completely drilled out and cemented according to current Division of Oil, Gas, and Geothermal Resources (DOGGR) regulations and to the satisfaction of our client.
Do have removal and major repair done by people trained and qualified in handling asbestos. It is highly recommended that sampling and minor repair also be done by asbestos professionals.
Don’t dust, sweep, or vacuum debris that may contain asbestos.
Don’t saw, sand, scrape, or drill holes in asbestos materials.
Don’t use abrasive pads or brushes on power strippers to strip wax from asbestos flooring. Never use a power stripper on a dry floor.
Don’t sand or try to level asbestos flooring or its backing. When asbestos flooring needs replacing, install new floor covering over it, if possible.
Don’t track material that could contain asbestos through the house. If you cannot avoid walking through the area, have it cleaned with a wet mop. If the material is from a damaged area, or if a large area must be cleaned, call an asbestos professional.
Major repairs must be done only by a professional trained in methods for safely handling asbestos.
Minor repairs should also be done by professionals since there is always a risk of exposure to fibers when asbestos is disturbed.
Doing minor repairs yourself is not recommended since improper handling of asbestos materials can create a hazard where none existed.
Removal is usually the most expensive method and, unless required by state or local regulations, should be the last option considered in most situations. This is because removal poses the greatest risk of fiber release. However, removal may be required when remodeling or making major changes to your home that will disturb asbestos material. Also, removal may be called for if asbestos material is damaged extensively and cannot be otherwise repaired. Removal is complex and must be done only by a contractor with special training. Improper removal may actually increase the health risks to you and your family.

Guideline for the Dismantling and Removal of Underground Storage Tank
Underground storage tanks (UST) are used for storage of liquids such as gasoline, diesel, fumigants, solvents, used industrial waste-water processing, sumps, pits, and other subsurface features that store, convey, or process chemicals and chemical waste.
Federal and State regulations prescribe strict design, operation, and decommissioning practices for USTs and other subsurface containers. Many states mandate specific requirements including permits, containment, monitoring, inspections, and sampling for the UST and closure of such subsurface elements. In the event that said subsurface container has been determined to be leaking, the cleanup of resulting soil contamination is typically under the oversight of a local agency, As such, groundwater investigation and cleanup activities are typically regulated by regional water quality control boards.
Steps for UST Removal:
A layout of all cuts is done for Andersen Environmental examination and analysis before commencing the excavation work.
When the top of the UST is uncovered the remaining liquids are removed with special care from the tank.
In the event that UST and/or piping contain any additional unused petroleum product or oil, all such products are emptied prior to removal of the UST or piping.
Extreme caution must be used when excavating and removing the UST to ensure that no spillage of any petroleum product occurs
When the UST is empty, it is removed from the excavation with the aid of an excavator. The UST is then cleaned and inspected by a certified industry hygienist.
All piping, pumps, wiring, gauges and other equipment associated with the UST are also removed.
Andersen Environmental will excavate any soils impacted by petroleum hydrocarbons. The impacted soils are placed directly into trucks for immediate off-site disposal. It is the responsibility of Andersen Environmental to collect and have analyzed the appropriate waste characterization samples according to Sate and Federal guidelines.
If the samples return positive of soil contamination, it must be removed.
The surface is restored to pre excavation condition. Appropriate measures are taken to ensure that there is no difference between the existing surfaces and the restored surfaces.
