. Each of the following cases could lead to a perception of less risk, excepta. an activity whose harm is delayed for many yearsb. something whose bad effects are ultimately reversiblec. something that is risky only at high exposuresd. something with a uniform exposure to risk whats the answer ? These are homework problems made up from book Engingeering Ethics By fledderman
A man works in an aluminum smelter for 10 years. The drinking water in the smelter contains 0.070 mg/L arsenic and 0.560 mg/L methylene chloride. His only exposure to these chemicals in water is at work. Recall the total HI (i.e. the total overall risk) is the sum of individual HI values. (a) What is the hazard index (HI) associated with this exposure? (b) Does the HI indicate this is a safe level of exposure?(c) What is the incremental lifetime cancer risk for the man due solely to the water he drinks at work and does it seem to be an acceptable risk according to the EPA’s standard of acceptable risk?

CASE STUDY: DEMANUFACTURING OF COMPUTERS Let’s consider a case that deals with a timely and important issue concerning environmental economics. What are companies to do with all of the old computers that typically accumulate at their facilities? As one possible solution to this problem, a number of states and companies have jointly established “resource recovery” facilities to process the handling of old electronic equipment, such as used computers. Demanufacturing of computers involves disassembly, refurbishing, and either donatingor reselling the units. However, there are some residuals, or remaining components, that cannot be reused, are harmful to the environment, and contribute to the cost of demanufacturing. Let’s consider the case of one resource recovery center in the Northeast that currently handles approximately 2,000 computers per year. Of these computers, approximately 50% are refurbished and donated, 40% are remanufactured and resold, and 10% are “residuals.” What to do…
The water engineer aims at prevention contamination of water supplies at all times. In most small water supply systems, however, economic reasons prevent 24-hour daily water service. This creates a risk of polluted water infiltrating into the pipelines through leaks in pipe joints and service taps. How would the water engineer ensure that the pollution do not pose a health risk to domestic consumption? Give example of factors to consider when selecting the material for the pipe.?

The EPA regulates water in the US supply and sets standards for drinking water. The water standards are enforceable under the Safe Drinking Water Act. These take into account the available technology and cost and are expressed as MCLs. The standards are more stringent and are expressed as Maximum Contaminant Level Goal or One inorganic chemical that is a water pollutant is . It causes nerve damage or are organic thyroid problems. compounds that can cause immune deficiencies, reproductive or nervous system difficulties, and increased risk of cancer. In addition to regulating inorganic and organic chemicals, radionuclides, disinfectants/disinfection byproducts, the EPA also regulates legionella, etc. including giardia, Drinking Water Treatment After debris removal and coagulation, the next step in the water treatment process is The water is then pumped through a settling tank and filtered. The settling tank, also called the , can be rectangular or The clarifier is designed in a way that…
Your organization has been hired to provide a water treatment process or device toremove toxic Chromium 6 [Cr(VI)] from water emanating from an underground source.Your organization has developed a treatment process that removes most of the Cr(VI)from the water to a residual concentration of 0.05 mg/L which is an acceptable level inline with the World Health Organisation. The underground water flows at 40 m3/h andhas Cr(VI) concentration of 100mg/L. The effluent flow rate is 97% of the influent flowrate, and the remainder of the water is discharged as wastewater. Calculate theconcentration of Cr(VI) in wastewater.
