Solid waste with the density of 110 kg/m3 is spread in a 0.5 m layer at a landfill. If a steel wheeled compactor can achieve a density of 400 kg/m3, what is the compaction ratio (CR)? Note:   CR= Vinitial/Vfinal

For subsurface investigation, soil borings are considered as:

Air stripping process is used as a pump and treat method for removing a trichloroethylene (TCE) from groundwater.  The following conditions apply: Influent flow rate = 40 m3/sec QA/QW = 20 Dimensionless Henry’s constant = 0.2 TCE concentration in the influent = 1.1 mg/L TCE concentration in the effluent = 50 µg/L The stripping factor is most nearly:

Carbon adsorption experiments have been conducted.  Plot of:  ln(X/M) vs ln(Ce) to determine the Freundlich constants a and b in the Freundlich equation (written as:  X/M = a Cf b ) provided the following linear equation: Y = 0.351 X + 2.131 Data collected correspond to which of the following Freundlich equation:

100 mL of a solution with a TOC (total organic carbon) concentration of 0.5% is placed in each of the five containers with activated carbon and shaken for 48 hours. The samples are filtered and the concentration of TOC measured, yielding the following analyses: Test beaker no.:          1          2          3          4          5 Carbon (grams):          10        8          6          4          2 TOC (mg/L):               42        53        85        129      267   The Freundlich isotherm is to be used:  X/M = k Cf 1/n The value of X/M in the 1st beaker is (mg/g):

Estimate the weekly volume of solid waste being delivered to a municipal landfill if the average solid waste generation rate is 2.6 kg/person∙d. The population is 17,200 and the density of solid waste delivered is 122kg/m3.   The waste to cover ratio is 4 to 1.  The air space will be used up in one week is most nearly (m3/week):
