(mchm) spilled at the elk river from a freedom industries coal treatment tank on january 9th, 2014. assume that the chemical is transported in the river via pure advection.
a. assuming that the river flows at a discharge of 270 m3 s-1 and has a cross-sectional area of 30 m2, at what time will the pollutant reach charleston, located 50 km downstream from the treatment tank?
b. the initial concentration was 2 ppm at the river freedom industries site. mchm breaks down in surface waters through photochemically produced hydroxyl radicals according to a half-life of 1 day. what will be the concentration of the chemical at the wastewater treatment plant, ignoring any dispersion?
c. how far downstream would you need to locate a drinking water intake to ensure that the chemical concentrations are less than 100 ppb? again, assume the chemical moves via pure advection.
