Kanchana has been working as an environmental engineer at a consulting firm for over twenty-five years. Well-known for settling disputes between his corporate clients before litigation must be pursued, Kanchana often analyses technical data, particularly distributions of solid particle pollution, presented by disputing parties to help them reach a compromise on the cost of environmental clean-up. For example, two parties may be separated from one another by a strip of land; however, each party must fiscally contribute in keeping the land free from pollutants.
One day, Kanchana was contacted by a journalist to talk about his experiences at the firm. Kanchana spoke about how he often encountered cases where companies did not accurately depict levels of solid particle pollution occupying the companies’ respective surroundings. Instead, technical experts, who are mostly engineers, would misrepresent data in order to make it seem that minority parties were responsible for a greater part of the contamination. At the end of the interview, Kanchana emphasized the necessity of engineers taking ownership and being honest about the presentation of data.

  1. What are the additional factors that might affect capacity and speed on freeways (hint: they don’t always exist, and the adjustment is not carried out if they are irrelevant in a given problem)? How do you make these adjustments?

The shallow sandy aquifer (4 feet thickness) is contaminated with 1,2-XYZ (K oc = 20 L/kg) at an average soil concentration of 800 mg/kg. A batch soil washing device is designed to treat 1,100 kg of contaminated soil (f oc = 0.004) with 900 gallons of clean water. Find the concentration of 1,2-XYZ in water and in soil and water after (a) one wash, and, (b) two wash.

A community’s groundwater has been contaminated by perchloroethylene after years of operation of a dry-cleaning business. Groundwater supplies a spring that feeds a pond and stream and is also the source for a well. A local family relies on the well for their drinking water and regularly eats fish caught in the stream and pond. The concentration of perchloroethylene in the groundwater is found to be 80 mg/L, and the chronic oral RfD is 0.006 mg/kg/day.

a.) Assuming all exposure to perchloroethylene comes from consumption of fish and water, and that children and adults eat the same amount of fish on average per day, calculate the Estimated Exposure Dose (EED) for an adult and a child.

b.) What are the adult and child hazard ratios (HR) for this scenario? Interpret the results.

The average body weight of an adult is 70kg, the average body weight of a child is 10kg, and the amount of fish consumed is 6.5g/day.

Produce a fully researched and referenced report (indicative word range 2,250–2,500 words) for a client that explains a particular system, type or design of an innovative modern method of construction suitable for a new primary school.
Your report should:
• include a critical appraisal that evaluates the relative merits of this method of construction over that of a more traditional type of construction;
• address various environmental and sustainability issues.

Please state any assumptions you make in the report. Assumptions can be made as to any specific type of facility, arrangements, layout or size. Please ensure that you write in your own words and that all sources are fully referenced.
Report guidance
The report could look at an offsite system of prefabricated schools.
