Exposure Pathways Analysis

Environmental Management and Risk Assessment

Summary of Analysis
Based on the exposure pathways given instruction and located the map line based on the map was given to get a clear view of the exposure location. Then draw up the map and located where exposures are analysis. After spoke to my professor about the instruction on how to add up the section to follow the assignment such as titles, tables and summary, and report in Microsoft pages. This is left fill cold minefield at Wilsonville, Illinois. Researching and comparing the finding from many government websites such as Environment Protection Agency, (EPA), Occupational Safety and Health Administration (OSHA), and WKU libraries scholars’ articles and journals. Many findings and evaluating reports on the incident on the location on EPA and OSHA websites were back in the last seven and 6 years ago, but the results are relevant to each other. I use recent articles and journals to reference to reflect my report paper. I completed the analysis by created types of pathways in two tables. The first table focuses on potential and complete pathways and the second table focus on the eliminated pathway. Thus, the readers or public or requesters can be easily accessing and understating the information based on the tables. I reported the finding based on the two pathway tables. Finally, on the report findings, I have included exposure information, preventive information, and also as well as public health issues.

It is indeed a good approach to fill mines that have been left open since open mines pose a risk of falling to the children and also adults residing near the mines; however, whatever is used to fill the mines is critical with regards to its impact on the environment (Azcue, 2012).  On that account, filling the site at Wilsonville, Illinois was a prudent idea but what was buried in the process of filling the coal mines is the problem. It is evident that the buried waste which is chlorinated liquid was used to fill the deep and open coal mines. It should be noted that chlorine has a potential negative impact on the environment. One can be exposed to chlorine through inhalation and ingestion. However, in this case, ingestion and inhalation by humans and animals is the exposure route while vegetation is through the uptake of nutrients from the soil.

As a result of the soil being contaminated, this poses a risk to the vegetation around the lake as well as the coal mines that were filled with the liquidated chlorine. It should be noted that chlorine at low levels can be considered as important micronutrients that plants use to kill some bugs. However, a high concentration level causes the plant to wilt or appear scorched and eventually die (Sasikumar, Azariah, & Nair, 1993). As a result of vegetation being exposed to chlorine, growth will be stunted and thus there will be a scarcity of vegetation. Animals that used to feed on the respective vegetation will face a shortage. In addition, the consumption of vegetation with high levels of chlorine by animals is likely to cause health problems to the animals especially on the stomach. However, in the case of soil being contaminated with chlorine people far from the filed mine and the creek lake area will not be affected since the soil is far from their respective homestead.

The greatest concern associated with the buried waste containing chlorinated liquid is on groundwater as an environmental media. The chlorinated liquid will percolate towards underground water reservoirs and this will be facilitated with rainwater which will make the chlorinated liquid less viscous hence percolate faster. There is a lake around the Wilsonville area that gets its water supply from underground water. That being the case, the lake is contaminated with chlorine. The lake water is used by birds and animals and, on that account, the birds and animals are exposed to the high levels of chlorine and with time will develop gastrointestinal problems.

People residing north of the site is at the risk of inhaling chlorine gas since the wind flows from South to North. The inhalation of chlorine has the capability to cause respiratory complications and this includes chest problems (Redlich, Blanc, Kuschner, & Gulati, 2012). There is a home on the south of mine site that was filled with chlorinated liquid and relies on groundwater for domestic consumption. The homestead is not at risk at the time moment since the underground water is not contaminated. However, the well is on the path of the plume (chlorine contaminant) and thus it poses a risk to the family since it is a matter of time before the well becomes contaminated with chlorine. Chlorine is used in water treatment to kill harmful bacteria and the levels used are within the recommended range. However, in the case of the private well, the chlorine level will be too high hence posing a health risk to the family members in the respective homestead. According to (Xue, et al., 2013), some of the health complications that one is likely to experience include;

  • The feeling of burning in the mouth,
  • Pain in the throat,
  • Stomach pain,
  • Stool containing blood,
  • Vomiting
  • Continuous ingestion of high level of chlorine is likely to lower the PH of the blood

Based on the potential impact associated with the buried chlorinated liquid to the environment and residents living near the site, it is important that mitigation measures are developed at an early stage.
