California Superfund Site: Frontier Fertilizer
Fight Air Pollution & Water Pollution With an Environmental Toxic Tort Lawsuit

Do you need a Toxic Tort Attorney in The Golden State? The EPA has designated Frontier Fertilizer in California as a Superfund site because of its amounts of environmental toxins and harm to the environment. You can read the report for the site below.

Some Superfund sites are on the National Priority Site Lists. The National Priorities List ("NPL") is the list of hazardous waste sites in the United States eligible for long-term remedial action financed under the federal Superfund program. Environmental Protection Agency regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL. The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation.

Sites are listed on the NPL upon completion of Hazard Ranking System (HRS) screening, public solicitation of comments about the proposed site, and after all comments have been addressed. EPA may delete a final NPL site if it determines that no further response is required to protect human health or the environment. Sites where a remediation was completed through the Superfund program are typically deleted from the NPL.

Living near Superfund Sites in California may place you and your family more vulnerable to developing a disease from exposure to the site and experiencing a loss of value for your property, but you can do something to to fight back: The EPA says,

[We have] set up a "Post Construction Completion" (or PCC) strategy to ensure that Superfund response actions provide for the long-term protection of human health and the environment. EPA's Post Construction Completion activities also involve optimizing remedies to increase effectiveness and/or reduce cost without sacrificing long-term protection of human health and the environment.

Below you can read the EPA report for the Frontier Fertilizer Superfund site. If you, a loved one, or someone in your community has gotten sick due to exposure to a Superfund site Frontier Fertilizer, or if your property has lost value because of contamination, you are better off with a toxic tort attorney who knows the people of the State of California . Take your first step filling out this simple form. There is no obligation, and your case will be evaluated within one business day.

NPL LISTING HISTORY

Proposed Date:01/18/1994

Final Date:05/31/1994

Deleted Date:

The principal chemicals in groundwater and soil are three pesticides which were used a soil fumigants: ethylene dibromide (EDB), 1,2-dichloropropane (DCP), and 1,2-dibromo-3-chloropropane (DBCP) as well as the solvent carbon tetrachloride.

Subsurface soil in the area of the former disposal basins is contaminated as well as groundwater in the S-1, S-2 and A-1 zones. The A-2 aquifer, which is the drinking water supply for the City of Davis, is not contaminated.

The California Department of Toxic Substances Control installed a small groundwater extraction and treatment system in early 1993. EPA installed a larger system in 1995. The system was upgraded in Fall 2000 and again in 2002. The groundwater extraction wells for the existing system are in the field immediately north of the site. EPA has also installed groundwater monitoring wells on-site, in the field immediately north of the site and in the Mace Ranch residential subdivision. EPA collects samples of water chemistry and measures water levels in these wells on a quarterly, semi-annual, or annual basis, depending on the location of the well.

EPA collected samples of groundwater and surface and subsurface soil to determine the nature and extent of contamination and reported the results in an April 1997 Remedial Investigation (RI) Report. The studies showed that soil contamination was confined to the waste disposal basins area, and that contaminated groundwater existed in the upper three water-bearing zones and had migrated off-site. A June 1999 Supplemental Remedial Investigation Report describes sampling results from newly installed groundwater monitoring wells in the Mace Ranch Park subdivision as well as soil gas sampling results. Soil gas samples were collected on top of the former waste disposal basins and every 50 feet from the pits to the Mace Ranch Park subdivision. Groundwater sampling data showed much higher levels of contamination on-site and immediately north of the site than existed in Mace Ranch Park. Soil gas concentrations were high on-site and decreased rapidly north of the site.

A Baseline Risk Assessment was produced in April 1999. An indoor air risk assessment for the residents of Mace Ranch was included in the Baseline Risk Assessment. The indoor air risk assessment determined that there is no risk to residents of Mace Ranch from volatile chemicals in groundwater moving up through soil and into homes.

In Fall/Winter 2001 and Spring 2002, EPA collected additional groundwater samples in the Mace Ranch subdivision and collected soil, soil gas and groundwater samples on-site and in the field immediately north of the site to better define the geology and extent of groundwater contamination. A groundwater extraction well cluster was installed at the intersection of Caricia Drive and Arroyo Avenue and in the field immediately north of the former waste pits. A new groundwater monitoring well cluster was installed on Fifth Street near Entrada.

The groundwater sampling results showed elevated concentrations in the S-1 and S-2 zones on-site and immediately north of the site. These concentrations generally decrease sharply within a few hundred feet of the former disposal basins, although there is a localized area of elevated pesticide concentrations in the S-2 zone near the intersection of Caricia and Arroyo in Mace Ranch Park. Soil gas concentrations were lower than those collected in 1997, indicating that the risk calculations performed for the 1999 Baseline Risk Assessment remain protective. Soil sampling identified a zone of soil contamination extending from near the ground surface down to about 30 feet below ground surface in the area next to the former disposal basins. Soil samples collected about 60 feet north of the disposal basins show contamination about 30 to 80 feet deep, although at much lower concentrations than the shallow soil contamination near the former disposal basins. The results of this field work are described in Supplement No. 2 to the Remedial Investigation Report, dated January 2003.

As described above, EPA has been operating a groundwater extraction and treatment system since 1995. While the system has been effective in removing contaminants from groundwater in the field north of the site, quarterly groundwater monitoring data shows that the system is not capturing all of the plume (the area of contaminated groundwater) in the Mace Ranch subdivision. Therefore, EPA is in the process of expanding the groundwater extraction and treatment system. The first steps were the installation of the groundwater extraction wells and the additional site characterization performed in Fall/Winter 2001 and Spring 2002. EPA is using all of the groundwater data (as well as historical data) to help produce a Site Conceptual Model (SCM). The SCM will help determine the optimal locations for additional groundwater extraction wells. EPA expects to construct the first phase of the expansion to the extraction and treatment system in Summer 2003.

EPA will evaluate cleanup options for the waste dispoal basins area (the source area) and the A-1 aquifer in a Feasibility Study and then holding a public hearing on the preferred cleanup alternatives. EPA expects to finalize the Feasibility Study and hold a public hearing in Summer 2004.
