Site Remediation
Integrated Engineers Inc.
The Wastewater Experts
Integrated Engineers initial proposal is to move on-site, remediate our contaminated soil and water and to build a waste water treatment plant in exchange for land.
Integrated Engineers plans on a 10,000 sq. ft building to house an office and shop. Their goal is to utilize local talent on their staff.
They currently employ staff that lives in Oakhurst, Coarsegold and North Fork.
Pilot Test for Bioremediation of PCP and
Diesel in Soil
Pilot Test Equipment: The equipment used consists of a 15 gallon plastic bin with cover, a shovel for mixing the soil, sample jars for sending samples to the lab for analytical testing, bacterial cultures, fertilizer, and water. Initial Start of the pilot test: Approximately 2 cubic feet of soil from the area of contamination located at the old dip tanks was placed in the 15 gallon plastic bin. A mixture of 12 ounces of water, 1/3 cup of bacteria, and 1 tsp of fertilizer was thoroughly mixed into the soil. The soil was turned and mixed with the shovel until it was homogeneously mixed making a paste like composition. A composite sample was taken for the initial determination of the contamination of PCP and diesel. The cover was placed over the soil/bin to keep the moisture in the soil. Procedures: Every day the bacteria is added with the fertilizer and thoroughly mixed into the soil. Water is added to keep the soil moist, but not to the point of any "free" water in the bin. The soil is mixed for about 3 minutes turning it over and allowing ambient air to contact the soil/bacteria mixture. Every 3 days, a composite sample is taken and sent to the lab for analysis. Expected Results: Over a period of 30-45 days, a curve will be made from the analytical data showing PCP & Diesel degradation over time. This will provide a true degradation rate specific to the sites actual conditions, eliminating the guess work from theoretical modeling. 40308 Greenwood Way Oakhurst, CA. 93644 Phone (559) 683-8284 Fax (559)683-8913
What are Dioxins and Furans?
"Dioxins and furans" refer to a group of chemical compounds that share certain similar chemical structures and biological characteristics. Dioxins and furans are an unwanted byproduct of combustion, both from natural sources like forest fires and from man-made sources like power plants, backyard burn barrels and industrial processes. According to the EPA, dioxins and furans released into the air during combustion can be carried long distances before settling to the earth's surface. As a result, they are found almost everywhere at low levels. Dioxins and furans are produced by both natural and man-made processes and have therefore existed for centuries. The term "current background" is used to refer to the levels of dioxins and furans in the environment today. Dioxins and furans falling to land from air emissions tend to bind tightly to vegetation and soil. When dioxins and furans are released into water, they tend to settle into sediments where they can become trapped and stationary, or be ingested by fish and other aquatic organisms. Dioxins and furans trapped in sediment can be further transported during activities that dislodge sediment, such as flooding or dredging. In the United States, the primary way people are exposed to dioxins and furans is through eating meat and dairy products. The animals we eat are exposed to background levels of dioxins and furans in the soil, on vegetation and in some commercial animal feeds. Eating meat or dairy products exposes us to these low levels of dioxins and furans Over time, we accumulate dioxins and furans in the fatty tissues of our own bodies.
