Under Virginia environmental law, what is the maximum allowable concentration of lead in soil for residential properties?
Correct Answer
C) 400 ppm
Virginia environmental regulations set the residential soil lead standard at 400 parts per million (ppm) for bare soil in play areas.
Why This Is the Correct Answer
Virginia environmental regulations, consistent with EPA standards, set 400 parts per million (ppm) as the maximum allowable lead concentration in bare soil for residential properties, particularly in play areas where children may be exposed. This threshold is used to trigger remediation requirements.
Why the Other Options Are Wrong
Option A: 200 ppm
200 ppm is below the established residential standard and would be overly restrictive. While lower concentrations are preferable, the regulatory threshold is 400 ppm. Selecting 200 ppm reflects an underestimate of the standard.
Option B: 800 ppm
800 ppm is double the correct standard and would allow hazardous levels of lead in residential soil. This level might be associated with industrial or non-residential areas, not residential properties where children play.
Option D: 600 ppm
600 ppm exceeds the 400 ppm residential standard and would not protect children from lead exposure adequately. It is a distractor placed between the correct answer and the overly permissive 800 ppm option.
Memory Technique
Remember '400 ppm for residential' — think of a 400-meter track surrounding a home: anything beyond 400 is out of bounds. Or: '4 is the limit for lead on land' (4 = 400 ppm). The EPA's residential soil standard of 400 ppm is a widely-cited benchmark.
