Outside the city of Five Points, a small illegal dump is found containing old computer monitors. The concentration of lead in the soil is 200 ppm in a primary area, a circular region with a radius of 7 meters centered at the dump. A secondary area with an additional width of 7 meters has a concentration of 20 ppm.
Lead can be treated at a cost of $9/m2 with phytoremediation with sunflowers or $45/m3 with removal of soil by excavation.
