Twin Cities Army Ammunition Plant: A Case Study
Twin Cities Army Ammunition Plant (TCAAP), located in Minneapolis, St. Paul, Minnesota, is a 2,370 acre facility that has been involved in the production of small arms ammunition, related materials, fuses and artillery shell materials. In 1981, it was recognized that contaminated groundwater from TCAAP was migrating into the Minneapolis, St. Paul metropolitan groundwater supply. The total soil Pb concentration ranged from an average of 2,610 to 358 ppm in the surface soil collected TCAAP. In addition to Pb, TCAAP sites contaminated with antimony, arsenic, beryllium, thallium, and chromium (Bader, 2000).

    Should Doctors Use Tc-99m In High Demand?

    Tc-99m is mostly a manmade substance. However, Tc-99m can be found in a few places throughout the environment. The few places that Tc-99m can be found is after detonation of nuclear weapon, airborne emissions from a nuclear reactor, airborne emissions from a nuclear fuel reprocessing plant, and the storage of radioactive waste in a facility, or a facility that treats radioactive waste. Since there are few places that produce Tc-99m there is a high need for the substance and is therefore manmade to keep up quantity.…

    Superfund

    At one time, Houston’s Fifth Ward contained a 36-acre fenced area, encompassing several debris piles, paved areas, and a few remnant structures. This once industrial area contained metal casting foundries that had created specialty molded steel parts that served as the foundation for industrial, railroad, and mining operations across the country. Also among the steel debris, were several used catalyst drums left by behind by a nearby chemical facility. Many Diversified Interests (MDI) was the last company to own the site, before filing for bankruptcy in 1992. Industrial operations had contaminated soils and ground water, and the U.S. Environmental Protection Agency (EPA) placed the MDI Superfund Site on its National Priorities List (NPL) of contaminated sites in 1999. While immediate threats to human health and the environment had been addressed, the site remained dormant for several years. Currently, the Superfund Site’s $6.6 million solution is complete, enclosing a flat open field where a new residential housing development is planned. The once ridden site will provide jobs, build the city’s tax base, and help sustain the ongoing renovation of Houston’s Fifth Ward. This case study explores the key factors that have led to a successful cleanup and planned renovation of the MDI Superfund site. This resolution at the MDI site proves how federal and state responsibilities can ensure the protection of human health and the environment with an end result reassuring a community’s quality of life. In the following pages, the remediation efforts will be discussed for the MDI site between its NPL listing in 1999 to the completed construction of the site’s solution in 2008.…

Northrop pays substantially less for a 2-bedroom apartment, in the same area all inclusive, for a 6-month lease. The COLSA rate, being on a 1-year lease, should be less than what Northrop Grumman pays. Instead, it is $1000.00 higher.…

    Missoula Water Sustainability

    Missoula receives 22% of its water flow from Milltown to Hellgate aquifer according to Missoula County Water Quality District (WQD). Missoula County WQD reported how severely this arsenic contamination affected Missoula’s water quality. An excerpt of the report showed: “The reservoir sediments contained an estimated 2,100 tons of arsenic and released 105 pound of arsenic per day or 19 tons per year into the Missoula aquifer. Approximately 5.5 trillion gallons of arsenic contaminated groundwater flowed downstream into the Missoula aquifer each year.” Actions have been taken to clean up Milltown Dam and currently no domestic wells exceed the arsenic drinking standards. The removal of the Milltown Dam was one of the largest efforts to decontaminate Missoula’s aquifer. Currently the Milltown Dam is not a threat for the Missoula aquifer but the dam could again become a possible threat and is monitored carefully.…

    Aroclor 1242: A Case Study

    Kittrell above and in many instances in his report many instances loosely describes NCRs knowledge that “PCBs” were “toxic”. Routinely both Dr. Rodricks and Dr. Kittrell lump all Aroclors under the one term, PCBs, when the focus in this matter should be on Aroclor 1242 and its differential toxicity and the evolving scientific information available over time for this product. Although there were well-known hazards associated with some PCBs in occupational settings, NCR’s investigations of possible toxicity of its CCP containing Aroclor 1242 (the Hill Top studies) had shown low to negligible toxicity, especially at lower concentrations. As described in my earlier reports, NCR had no scientifically credible reason to conclude that the potential toxicity of CCP and its components would likely result in risks at environmental levels of exposure.…

    Case Study

    Recently, complaints about contaminated water supply emerged and the Cobb County Water & Sewer Authority contacted GDEP to assist them in investigating the cause. An anonymous tip from a former Multi Phase Equipment employee alleged that the company had improperly stored PCBs on the company property, suggesting that it may be causing the contamination of water. GDEP then excavated several parcels of land on the plant site, finding out that improper packaging and storage of PCB’s has actually been carried out. There were several PCB drums buried on a small area of land near the river which should have been properly disposed.…

    Arsenic Poisoning

    Arsenic contamination of groundwater is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deeptubewells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. In addition, mining techniques such as…

    Remedial Action Case Study

    The first action taken was to conduct a geoprobe soil sampling and analysis, in order to determine the spatial extent of VOC and metal contaminations. The geoprobe study showed that the upper soils (depth less than 6 m) were not heavily polluted, and the VOCs in the soils were below the cleanup levels. Therefore, soil treatment via the SVE system was not warranted. Before the whole geoprobe study finished in June 1995, some other activities were taken. The first one was to determine the demolition of the Circuitron building. Though in OU-1 ROD the building was not determined to be demolished, subsequent investigations showed that he building had deteriorated markedly, and therefore it was decided to demolish the building. The demolition of the building was initiated in June 1996. After that, the activities that were chosen to remedy contaminated soils in the geoprobe study were initiated in November, 1996 and completed on December 20, 1996. The most important thing is to remove underground structures and sediments and soils in or around them. They removed building flooring, sediments in the leaching pools and those pools themselves, the soil surrounding those underground structures, and some roll-off containers. After these activities, approximately 50 tons of contaminated sediments and 1200 tons of contaminated soils were removed. Besides, they sampled the wastes that was left from previous activities for full RCRA Toxicity…
