1. ( 10 points) if 100 ork ( 100 points): would be the difference of farmland are converted to urban housing ( 4 houses per acre), what had an irrigation rate of in annual water requirements for that land? Assume that the farmland household has 3 people 0.5 acre f/month for a 6 month growing period, while the average (Note: 1 acre* 3 people with a per capita use rate of 165gped. I ft) 2. (15 points) Tables 4.1 and 4.2 from the USGS Publication "Estimated Use of Water in the United States in 2015" (USGS Circular 1441) are attached to this assignment. Use them to prepare a table showing the values below for the following states: Kansas, New York, Louisiana, Arizona, North Dakota a. the per-capita freshwater withdrawals, b. the percentage of freshwater withdrawn as groundwater c. the % of total freshwater withdrawn for public supply, irrigation, and industry. 3. (15 points). For each state, analyze your results, and identify the major future water challenges you would expect in 2-3 sentences. 4. (12 points) Find the current MCL and MCLG values for carbon tetrachloride, an industrial solvent, and antimony, a trace element. Explain briefly the health effects of exposure and the relationship between the MCL and MCLG for each compound. (HINT: The most complete source of information on drinking water regulations is the US EPA website, www.epa.gov.) 5. (10 points) A community has a population of 88,000 in 2020 and an average per capita water demand rate of 145 gallons per person per day (gped). Estimate the community's average water demand in 2030 assuming the population has increased by 35% but per capita water demand decreases by 4%
