Answer the following statements true (T) or false (F)
1. The center-to-center spacing of vertical reinforcement in a CMU wall cannot be less than 8 in. 2. The terms pilaster and pier are synonymous. 3. A split-face CMU is made by treating a standard CMU with an oxyacetylene torch to produce a very smooth surface on one or more faces of the unit. 4. A burnished CMU is made by treating a standard CMU with an oxyacetylene torch to produce a very smooth surface on one or more faces of the unit.
The US EPA’s Maximum Contaminant Level (MCL) in drinking water is 0.005 mg/L or 5 ppb for carbon tetrachloride. The carbon tetrachloride concentration in the soil outside of a factory is 0.01 mg/kg, and the soil has a 1% organic content. carbon tetrachloride has a reported octanol-water coefficient equal to 400. Estimate the organic carbon normalized partition coefficient, Koc, using the estimation procedures based upon equations 2.73 and 2.74 and the sediment/water partition coefficient. Use the sediment/water partition coefficient to predict the possible equilibrium concentration of carbon tetrachloride in the groundwater.
