				or other procedures adopted by the appropriate regulatory agency.
2) Groundwater elevation in a groundwater
				monitoring well must be determined and recorded when necessary to determine the
				gradient.
3) The analytical
				methodology used for the analysis of constituents in Subparts C and D must be
				consistent with both of the following:
A) The
				methodology must have a PQL at or below the preventive response levels of
				Subpart C or groundwater standard set forth in Subpart D, whichever is
				applicable; and
