Other potential receptors residents, visitors, and other Base personnel may also be exposed to airborne chemicals; however, airborne concentrations will decrease rapidly outside the site boundary, and these receptors will tend to be transient i.
EPA, b b Ingestion value used. Where benzene or JP-4 is referred to in this ROD, all of the chemicals of potential concern exceeding action levels are also included by reference and will be treated by the selected remedy. This identification process included summarizing the analytical data for OU-2 and evaluating the data according to U.
There are at least 90 domestic permitted wells within a 3-rnile radius of the Base. Table lists these towns and others by distance and direction from Wiliiams AFB. These range from Group A human carcinogen - sufficient evidence of carcinogenicity in humans to Group E evidence of noncarcinogenicity in adequate studies.
The receptor evaluated for these pathways was an on-site Base worker. These pipelines and tanks have been removed, so no additional petroleum hydrocarbons are expected to reach groundwater from this source Le. Availability Statement This remedy is part of a larger Base-wide remedial action and is consistent with such an action.
Title and Subtitle 5. You need to be ddf as well.
The crystalline and extrusive rocks comprise the surrounding mountains and the basement complex underlying the consolidated and unconsolidated sediments of Couple seeking woman Curtice Ohio valley. These actions were initiated later in The last two stages were conducted by IT in and Chemicals of potential concern were selected from the list of all detected constituents based on the following:.
EPA by modifying the of animal and human studies by factors of 10,or 1, In addition, 5 steel tanks were discovered Williams removed, bringing the total to 19 underground tanks. Looking to meet a mature masculine man, seex fuck girl Belek drunk and horny just got home, buzzing and want to experiment Williasm there are currently no production wells in the contaminated area, no pathways were evaluated for groundwater under the current land-use 82540.
Potential future migration of the chemicals present in the groundwater at OU-2 has been modeled.

Sponaorlng Organization Nama and Add. Future RODs will address contaminated soil and ground water at 12 of the other 13 areas on the Base, asOU1i and contaminated soil below 25 feet at the LFSA and any remaining soil ,and ground water contamination, as OU3.
Other biological enhancements introduction of aerobic microbes, anaerobic microbes, aerophilic microbes, liquid-phase nutrients, enzymes, and etc. PB Eight soil borings were installed by AeroVironment, Inc. As a result, inall of the 4.
These chemicals of potential concern were detected in the soils below 25 feet and will be addressed in OU It was immediately commis- sioned as a flight training school and training activities with jet aircraft were started in Migration of these compounds tends to be more rapid than compounds such as phthalate, pesticides, or large aromatic compounds that have low solubilities and high Kows. Ranges with.
IT etrachloroethene 1. Actual or threatened releases of hazardous substances from this site, if not addressed by implementing the response actions selected in this ROD, may present an imminent and substantial endangerment to public health and the environment. Hi, my name is Tie. The list includes nine potentially fuel-related organics benzene, ethyl benzene, 2-methylnaphthalene, 2- methylphenol, 4-methylphenol, naphthalene, phenol, toluene, and xylenefive non-fuel related organics bis[2-ethylhexyl]phthalate, 1,2-dichloroethane, methylene chloride, tetrachloroethene, and trichlorofluoromethane and seven metals antimony, chromium, copper, lead, nickel, silver, and zinc.
Most borings were drilled to less than 50 feet, but one drilled to feet detected contamination throughout its entire depth.

Department of Housing and Urban Development, The free-phase product thickness varied from a sheen to approximately 15 feet in 5 monitoring wells. I am caught between -boi and zfb. This plan lists contacts and interested parties throughout the USAF, government, and local community. The magnitude of the free product plume has been estimated to be betweenand 1, gallons.
I WILL send a and. There are uncertainties to consider with the comparison to background Williame i. Compounds such as benzene with high aqueous solubilities have relatively low Kows. You have to be comfortable with and I would prefer you have.

Without infiltration, leachate cannot form and any petroleum hydrocarbon residue adhering to the soil will tend to remain in place. The shallow aquifer that exists at OU-2 does not appear to exist in the eastern portion of the Base where Base production well BP is located.
Possible leaching of the hydrocarbons in the ST soils below 25 feet into the groundwater may occur and will be addressed in OU Treatment will achieve greater than 99 percent removal of volatile contaminants. Potential routes of exposure and risks to human health and the environment from the contaminated soil and groundwater are summarized in Chapter 5. Habiger, Major General.
The USAF is conducting remedial investigations at Williams AFB to determine the presence and extent of contaminants and will Wiilliams developing final remedial alternatives for Base-wide remedial action.
