Abstract: This manuscript describes a database of US state regulatory guidance values assembled to examine the guidance applied to the most commonly regulated surface soil contaminants. Guidance values were identified for 994 different contaminants, but there is considerable variability in the number of contaminants regulated by each state and in the values applied to contaminants. Guidance values for the 40 most-regulated organics vary by an average of four orders of magnitude. Details are presented for guidance applied to naphthalene, benzene, toluene, ethylbenzene, dimethylbenzene, Lindane, phenol, trichloroethylene, benz[a]anthracene, and methoxychlor to illustrate statistical properties of value variation.

Keywords: surface soil contamination; organic pollutants; regulatory guidance values; risk analysis; soil remediation; database analysis; environmental pollution; USA; United States.
