- A water quality control board reports that water is unsafe for drinking if the proportion of nitrate concentration exceeds 21% ppm. Water specimens are taken from a well. ?o: ??:Sediments reaching streams affect water clarity, which is tested by determining turbidity Turbidny can be determined by measuring the depth at which a submerged object can no longer be seeo from the surface due to how much sediment is "clouding" the sample. The lower the turbidity, the more sediments causing the water to be "cloudy." Below is a table of the results. Sample Group Turbidity Straw bale plots (plot A) 12 cm Planted grass plots (plot B) 28 cm (vii) Based on the data in the table above, make a claim about the stated hypothesis. PLAT PTTO TONIC THEA oYCase: A porous but low permeability, old reservoir was evaluated by a group of petroleum engineers in Marmul. From subsurface rock-sample taken to the laboratory, they verified the presence of remaining heavy oil but there was also a skin damage in the formation as well as near the corroded wellbore liner. Surprisingly, during a second sampling in the deep part of the reservoir, they also found a significant amount of methane that was trapped in the same formation. The supervisor wanted to try a well-stimulation method on this old reservoir to improve the flow of reservoir fluids, including the hydrocarbons that remained trapped in the rock formation. What well stimulation method would you suggest? Why?
- Explain in simple terms “acidic rainwater can leach aluminum from soil clay particles and then flow into streams and lakes.”Standard trash (like a cup) is not considered a pollutant because it can be placed into a landfill and processed. True or False.What is an advantage of deep-well disposal of liquid hazardous wastes? Liquid wastes are safer than solid wastes. Well casings never leak. Waste production is discouraged. Carbon dioxide and other air pollutants are not emitted. Wastes can often be retrieved.
