Current through Register Vol. 47, No. 3, July 24, 2024

General.
When analyzing for petroleum or hazardous substances,
				owners and operators of UST systems must use a laboratory certified under
				567-Chapter 83. In addition they must ensure that all samples are properly
				preserved and shipped within 72 hours of collection to a laboratory certified
				under 567-Chapter 83. This rule provides acceptable analytical procedures for
				petroleum substances and required information that must be provided in all
				laboratory reports.

Laboratory report.
All laboratory reports must contain the
				following information:
a. Laboratory name,
				address, telephone number and Iowa laboratory certification number. If
				analytical work is subcontracted to another laboratory, the analytical report
				from the certified lab which analyzed the sample must be submitted and include
				the information required in this subrule.
b. Medium sampled (soil, water).
c. Client submitting sample (name, address,
				telephone number).
d. Sample
				collector (name, telephone number).
e. UST site address.
f. Clients sample location
				identifier.
g. Date sample was
				collected.
h. Date sample was
				received at laboratory.
i. Date
				sample was analyzed.
j. Results of
				analyses and units of measure.
k.
				Detection limits.
l. Methods used
				in sample analyses (preparation method, sample detection method, and
				quantitative method).
m. Laboratory
				sample number.
n. Analyst
				name.
o. Signature of analyst's
				supervisor.
p. Condition in which
				the sample was received at the laboratory and whether it was properly sealed
				and preserved.
q. Note that
				analytical results are questionable if a sample exceeded an established holding
				time or was improperly preserved. (The recommended holding time for properly
				cooled and sealed petroleum contaminated samples is 14 days, except for water
				samples containing volatile organic compounds which have a 7-day holding time
				unless acid-preserved.)
r.
				Laboratory reports required by this chapter for tank closure investigations
				under 567-135.15 (455B) and site
				checks under 135.6(3) or Tier 1 or Tier 2 assessments under
				567-135.9 (455B) to
				567-135.11 (455B) must include a
				copy of the chromatograms and associated quantitation reports for the waste
				oil, diesel and gasoline standard used by the laboratory in analyzing submitted
				samples. The laboratory analytical report for each sample must state whether
				the sample tested matches the laboratory standard for waste oil, diesel or
				gasoline or that the sample cannot be reliably matched with any of these
				standards. A copy of the chromatograms and associated quantitation reports for
				only the soil and groundwater samples with the maximum concentrations of BTEX
				and TEH must be included.
