Module 5 Disaster Scenario-Landfill Leachate
Module 5 Disaster ScenarioLandfill Leachate: A local landfill’s retaining area has been compromised from years of neglect and burial of unauthorized substances. There is concern that the leachate has reached the local ground water, which is a drinking water source for the community, a food source from its plentiful fish, and a recreational waterway where people swim. Community residents are convinced that there is a cancer cluster in their community, which is related to this contamination. Your team will need to define at least two chemicals that have been found in the leachate and their associated risks for being related to a cancer cluster. Part 1: Disaster Response Quiz (Short essay answer)You received a disaster scenario from your Instructor. Respond to the following questions as they relate to your scenario.Question (12 points for each question)ResponseScoreIdentify at least two relevant agencies that would be involved in this disaster response and their respective roles, in brief. Characterize the likely environmental contamination resulting from the disaster. Be sure to describe environmental fate, transport, and persistence, where applicable.Identify the population at risk of exposure. Are there any susceptible/sensitive populations of concern?Choose one possible environmental exposure from your provided disaster scenario that has the potential to impact human health. Describe how this exposure would be measured in the population at risk. Be sure to consider characteristics of the exposure (e.g., in both the environment and via biological media).What might be an appropriate study design to determine whether this exposure is related to excess morbidity or mortality in the population, and why?Instructor comments:Total Score (60 possible points)Part 2: Odds RatioThe following 2 x 2 table represents a study of exposure X and disease Y relating to your provided disaster scenario. Using these data in the table below, calculate the appropriate ratio measure of association for your chosen study design. Interpret the result in terms of the exposure you selected and a health endpoint plausibly related to the exposure.DiseasedNot DiseasedExposed65120185Not Exposed2013515585255Odds ratio:Risk ratio:Interpretation:
