A backhoe operator is hired and required to dig no less than 3 holes.
The first hole is the observation hole. This is where we find the limiting factor which is usually >50% rock or water table. The second and third holes are the perc test holes that are 4’ above the limiting factor. The water has 30 minutes per inch to percolate for a conventional septic system and 60 minutes per inch in an infiltrometer for a sand mound test.
The FCHD sanitarian conducts the official percolation test and records (COMAR 26):
Perc time Location of perc/observation holes Depth of perc holes Any other information pertinent to the solid and site characteristics of the property.
2. A mobile unit operating on a routine basis requires an annual Food Service License and the mobile unit must be in full compliance with Maryland’s Food Service Regulations (COMAR 10.15.03). Operating as an annually licensed mobile unit in Frederick County will also allow you to participate at public events in Frederick County without the need of additionally obtaining Temporary Food Service Permits.
In order to obtain annual licensure for a mobile unit, an operator can:A) Have a mobile unit constructed. This option requires submitting plans to be reviewed and approved by the Frederick County Health Department Food Program prior to the start of any construction. (Plan review fee is required.)B) Purchase a pre-owned mobile unit that is already outfitted with necessary equipment. This option is more risky to the operator because mobile units licensed in other jurisdictions may not be automatically licensed in Frederick County. It is recommended that when shopping for pre-owned mobile units, pictures of the mobile unit (including equipment, sinks, and plumbing detail, etc.) are submitted for evaluation prior to purchase.
Most mobile units require a “Base of Operations” in order to comply with COMAR 10.15.03. This is where the mobile unit will get potable water, dispose of gray water, dispose of grease from fryers (if need be), use the larger 3 compartment sink for cleaning and sanitizing equipment on the mobile unit, and where the mobile unit may have storage as needed. An additional license may be required for the “Base of Operations” if the kitchen is being used for more than clean-up, minimal storage, and/or minimal prep.
Facility must provide a letter on letterhead indicating permission for the mobile unit operator to use the facility as its Base of Operations.
If facility is not located within Frederick County, a copy of the facility’s current Food License is also required.
A menu must also be submitted for review and a HACCP plan will most likely be required ($75 review fee).
Additional license may be required for the “Base of Operations” if the kitchen is being used for more than clean-up, minimal storage, and/or minimal prep.
Waste water tank must be larger than the potable water tank.
Exterior access to fresh water tank must be lockable.
Operable windows require screens.
AC may be required depending on equipment and operation during summer months.
Licensed mobile units are not permitted to have food service outside the unit – includinggrills and smokers.
ATSDR’s Public Health Assessment estimated the TCE and PCE exposure doses to residents of those houses by using the maximum measured concentrations of the chemicals in 1992 (when potable use of the wells ceased). Evaluation of these contaminants and estimated ingestion doses of TCE and PCE for children and adults lead to the following conclusions:a) "Harmful effects are unlikely for users of the contaminated private wells based on maximum measured concentrations of PCE and TCE (cancer and non-cancer health effects).b) Residences with contaminated wells are currently being provided with alternate water. Current exposure to VOCs at these locations is limited to incidental use of the wells for irrigation or other outside uses. These exposures are unlikely to result in any harmful health effects.

When trying to determine whether a group of cancers is due to chance alone, or is a true “cluster,” some of the questions that should be asked include: (a) Is this the same type of cancer, or is it many different types?; (b) Are the cancers occurring in people who typically get this kind of cancer, or are these cancers happening in people who don’t typically get this type of cancer?; (c) Are the cancers occurring in people who are known to have a specific exposure?; (d) If an exposure is suspected of being related to a cancer, is there a reasonable period of time between when the exposure happened and when the cancer happened (because chemicals that are known to cause cancer typically take several years to several decades between when the exposure happens and when the cancer is finally apparent)?; and (e) Are the cancers common cancers, or are they very rare types of cancers?
The Maryland Cancer Registry is an ongoing registry since 1992, and the data are used for many different purposes. For example, data are used to look at the numbers and rates of cancer by type of cancer, race, ethnicity, age, gender, and geographic residence. In addition to all of its other responsibilities, the Registry provides data to the counties, which use the data to target cancer surveillance, screening, and prevention activities in conjunction with local health care providers and organizations. The review of state cancer data, to determine whether any particular area has more cancer than would be expected under normal circumstances, is a complicated task that requires additional resources beyond the other activities of the Registry and the health department. However, both the state and county health departments are committed to providing resources to this review of Registry data, because of community concerns.
The Frederick County Health Department conducted a Community Health Assessment in 2007 by surveying Frederick County residents. Participants were asked about a past diagnosis of non-skin cancer and modifiable risk factors associated with the development of cancer. The responses were then reported out separately for respondents from Central Frederick County, Northern Frederick County, and Southern Frederick County. The full Community Health Assessment can be found at http://www.frederickcountymd.gov/index.aspx?NID=2371 .For more information: Question and Answers about Cancer Clusters (Maryland Department of Health and Mental Hygiene) http://fha.maryland.gov/pdf/cancer/mcr_combined_cancer_cluster.pdf
The Maryland Department of Health and Mental Hygiene began its preliminary investigation using data that was already collected by the Maryland Cancer Registry. The initial cancer investigation is being conducted to answer questions and concerns that have been raised by Frederick County residents about cancer in the area, and proceeded independently of any ongoing issues related to environmental remediation at Fort Detrick. As additional concerns are raised as a result of this preliminary investigation and any future investigations, they will be addressed by the Frederick County Health Department, working together with the appropriate state and federal agencies.
Area B has been the primary location of waste management activities for Fort Detrick and is the location of an active municipal landfill, animal farm, former skeet range, former explosives storage area, and former waste disposal/test areas associated with former research activities.
In the late 1940s, the Special Operations Group of Fort Detrick installed a test grid in Area B to test both live and simulant biological warfare (BW) materials. A list of the live agent materials used in Area B is not available, but it is known that simulant materials used included Bacillus globigii, Serratia marcescens, and Escherichia coli. Test animals were buried in trenches or pits located in Area B after autoclave sterilization. Many types of munitions were tested on the test grid in Area B.
Anthrax was buried in Area B. In addition, radiological tracer materials were reportedly buried at three locations in Area B, including radioactive carbon, sulfur, and phosphorous. Two cylinders marked “Phosgene” were also reportedly buried in Area B. Phosgene is considered a lethal chemical agent.
In 1970 and 1971, after the United States outlawed biological research for offensive operations, a decontamination program was initiated for Fort Detrick. Decontamination procedures for residual biological/chemical research materials included autoclave steam sterilization and incineration. Incineration ash was tilled into soil in the northwestern corner of Area B (Pit 13). Research buildings and equipment were also decontaminated, and an extensive wipe sampling program was completed after decontamination. In addition, sewage drainage lines were cut and capped, and drainage systems were filled with hypochlorite solution.
In 1977, severe soil erosion exposed buried scrap materials and created several deep cavities in Area B. The areas were subsequently covered with soil.
In June 2004, a removal action was completed at Area B-11, an Area B chemical disposal area. Activities completed included the removal of contaminated soil, chemical containers, compressed gas cylinders, and laboratory waste. The discovery of live pathogens in medical wastes at Area B-11 caused suspension of all intrusive work at the disposal area. The southwestern portion of Area B contains three known chemical waste disposal pits (Pits 1, 3, and 4), one suspected chemical waste disposal pit (Pit 2), and one ash disposal pit. Area B-11, also known as Pit 11, is reported to have received various types of waste chemicals from Fort Detrick, the National Bureau of Standards, and the Walter Reed Army Medical Center from 1955 to 1970.
Reportedly, eight 55-gallon drums of TCE were disposed of in Pit 1. Wastes disposed of in the pits included metals, wood, general waste from laboratory modifications and building demolition, refuse from housing and animal farm operations, acids and chemicals, incinerated medical waste, waste herbicides and insecticides, phosgene, and animals potentially contaminated by anthrax. Area B-11 is underlain by solution-weathered limestone of the Frederick Formation, a karst formation aquifer. Solution features such as voids were identified in Area B-11 during the installation of monitoring wells. The voids are 10 to 87 feet long and were encountered with the greatest concentration in the first 100 feet of drilling. Drilling in Area B-11 revealed that bedrock is located at 32 to 33 feet below ground surface (bgs). The nature of karst conditions in Area B-11 increases the probability of releases to ground water from wastes disposed of in Area B-11. Wastes may have been disposed of directly into karst solution cavities (voids). All of these disposal activities could have resulted in ground water contamination.
The EPA has requested that the Army undertake an Archives Search Report to identify all materials used, tested, and disposed of at Area B over time. Such historical information will aid in determining what potentially could exist at Area B.
The EPA maximum contaminant level for the amount of tetrachloroethylene that can be in drinking water is 0.005 milligrams tetrachloroethylene per liter of water (0.005 mg/L). The Occupational Safety and Health Administration (OSHA) has set a limit of 100 ppm for an 8-hour workday over a 40-hour workweek. The National Institute for Occupational Safety and Health (NIOSH) recommends that tetrachloroethylene be handled as a potential carcinogen and recommends that levels in workplace air should be as low as possible.

TCE is Trichloroethylene (TCE), a nonflammable, colorless liquid with a somewhat sweet odor and a sweet, burning taste. It is used mainly as a solvent to remove grease from metal parts, but it is also an ingredient in adhesives, paint removers, typewriter correction fluids, and spot removers. Trichloroethylene is not thought to occur naturally in the environment. However, it has been found in underground water sources and many surface waters as a result of the manufacture, use, and disposal of the chemical.
Some studies with mice and rats have suggested that high levels of trichloroethylene may cause liver, kidney, or lung cancer. Some studies of people exposed over long periods to high levels of trichloroethylene in drinking water or in workplace air have found evidence of increased cancer. Although, there are some concerns about the studies of people who were exposed to trichloroethylene, some of the effects found in people were similar to effects in animals. In its 9th Report on Carcinogens, the National Toxicology Program (NTP) determined that trichloroethylene is "reasonably anticipated to be a human carcinogen." The International Agency for Research on Cancer (IARC) has determined that trichloroethylene is "probably carcinogenic to humans."
The EPA has set a maximum contaminant level for trichloroethylene in drinking water at 0.005 milligrams per liter (0.005 mg/L) or 5 parts of TCE per billion parts water. The EPA has also developed regulations for the handling and disposal of trichloroethylene. The Occupational Safety and Health Administration (OSHA) has set an exposure limit of 100 parts of trichloroethylene per million parts of air (100 ppm) for an 8-hour workday, 40-hour workweek.

VC has been found in the source area near the B-11 pit. In 2007, 21 Area B monitoring wells were sampled with only 1 detection of VC (9.6 ppm, in BMW 56D) near the B-11 pit area. There were no off-site detections of VC. Consistent levels of vinyl chloride (VC) throughout the contaminant plume would indicate that the known contaminants (i.e. TCE, PCE) may be naturally degrading through the process of dehalogenation to a benign endpoint (i.e. ethane) through biologic and natural processes. Certain anaerobic bacteria, principally Dehalococcoide ethenogenes, have been shown to effectively accomplish this conversion. The optimum pH range for D. ethenogenes has been reported in scientific literature as neutral to slightly alkaline, i.e., between 7 & 7.5. During the 2007 sampling event, the average pH reported was 7.56 or slightly beyond the optimum pH range. Also, with the exception of the anaerobic pit areas in Area B, the aquifer is oxygenated (i.e., aerobic). For this reason, significant D. ethenogenes activity is unlikely to be detected beyond the pit areas.
With regard to toxic air pollutants (TAPs), screening levels (i.e., acceptable ambient concentrations for toxic air pollutants) are generally established at 1/100 of allowed worker exposure levels. The Maryland Department of Environment has also developed additional screening levels for carcinogenic compounds. The additional screening levels are established such that continuous exposure to the subject TAP at the screening level for a period of 70 years is expected to cause an increase in lifetime cancer risk of no more than 1 in 100,000.
The Fort Detrick incinerators are required to perform routine stack testing in order to demonstrate compliance with both federal and State emission standards. Based on these stack test results, Fort Detrick is in compliance with both the Federal and State regulatory requirements for air emissions. In addition, the same controls would reduce emissions of other unregulated toxic air pollutants.
There are 7 principal dioxin compounds, 10 furan compounds, and 12 polychlorinated biphenyl (PCB) compounds which act similarly and may pose potential health risks. The compounds in this group (dioxins, furans, and PCBs) have different levels of toxicity, so a particular level of one compound does not necessarily pose the same risk as an equal level of another compound in the group. Dioxins are widespread environmental contaminants that tend to be present in soil at background levels. The background level of dioxins and related compounds in Frederick County has not been determined.
The only dioxin results reviewed by U.S. EPA thus far were submitted by John Bee on behalf of the Kristin Renee White Foundation. These soil samples, when evaluated in terms of 2,3,7,8-TCDD equivalents (2,3,7,8-TCDDeq), revealed dioxin levels (up to 7.89 parts per trillion [ppt] 2,3,7,8-TCDDeq) that are within the background range expected for rural areas of the U.S. (up to 11 ppt 2,3,7,8-TCDDeq ).
None of the levels reported in the referenced sampling effort exceed U.S. EPA's current residential clean-up standard for dioxin (1000 ppt 2,3,7,8-TCDDeq), proposed interim Preliminary Remediation Goal (72 ppt 2,3,7,8-TCDDeq) or risk-based concentration for residential exposure (450 ppt 2,3,7,8-TCDDeq), at an excess cancer risk of 1 in 10,000). As part of the ongoing investigation of Area B, EPA and MDE are discussing how best to conduct dioxin sampling for both on-post and off-post locations. This effort should provide more thorough coverage than the limited dioxin sampling conducted to date, and should capture the extent of dioxin contamination, if any, in the vicinity of the Area B.
If the Maryland Department of the Environment determines that there are area-wide contaminations that could impact individual private wells, an investigation in collaboration with the local County Health Department will be made. Depending on the significance of the contamination and number of impacted wells, corrective actions will be recommended. If wells are contaminated at a level that exceeds federal or State drinking water standards, solutions under consideration will include the provision of public water. There is also the option for the responsible party (e.g. Ft. Detrick) to request that the City connect those properties.
