New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 26E - TECHNICAL REQUIREMENTS FOR SITE REMEDIATION › Subchapter 2 - QUALITY ASSURANCE FOR SAMPLING AND LABORATORY ANALYSIS › Section 7:26E-2.1 - Quality assurance requirements

Current through Register Vol. 56, No. 14, July 15, 2024
(a) The person responsible for conducting the remediation shall ensure that all sampling and laboratory analysis are conducted, and results are reported, as follows:
1. Laboratories or companies involved in any laboratory or field activity that provide data of known quality must have all applicable certifications for the specific parameters or categories for which certification exists pursuant to the Regulations Governing the Certification of Laboratories and Environmental Measures, N.J.A.C. 7:18;
2. For the analysis of samples for parameters or categories of parameters for which certification is not available pursuant to N.J.A.C. 7:18, the person responsible for conducting the remediation shall ensure that the selected laboratory is capable of performing the analysis and meeting the data quality objectives specified in the site specific QAPP prepared pursuant to N.J.A.C. 7:26E-2.2. At such time as certification for the affected parameters or categories of parameters is codified in N.J.A.C. 7:18, the procedures in N.J.A.C. 7:18 shall be followed;
3. Derive the reporting limit for an organic compound analyzed by a particular method from the lowest concentration standard used in the calibration of the method as adjusted by sample specific preparation and analysis factors (for example, sample dilutions and percent solids), and derive the reporting limit for an inorganic compound analyzed by a particular method from the lowest level check standard;
4. Use the analytical method(s) that have analytical sensitivity sufficient to accurately measure concentrations to meet the data quality objectives detailed in the site-specific QAPP;
5. Perform sample matrix cleanup methods, where necessary, to reach the analytical sensitivity specified in the site specific QAPP;
6. Analyze all samples for petroleum products using the Department's Extractable Petroleum Hydrocarbon Methodology, "Analysis of Extractable Petroleum Hydrocarbon Compounds (EPH) in Aqueous and Soil/Sediment/Sludge Matrices" dated October 2008, Revision 3, August 2010, which can be found on the Department's website at
www.nj.gov/dep/srp/guidance/srra/eph_method.pdf
as amended and/or supplemented.
7. Use canister-based collection techniques for the analysis of air samples when analyzed by NJDEP Method LLTO-15 which can be found on the Department's website at
www.nj.gov/dep/srp/guidance/vaporintrusion/newmethod2007/llto15.pdf
or USEPA Method TO-15, incorporated herein by reference, as amended and/or supplemented, found on the USEPA's website at
www.epa.gov/ttn/amtic/airtox.html
;
i. When using USEPA Method TO-15 analyses, prepare a laboratory control sample and analyze at a frequency of at least one per every 24-hour analytical sequence and concurrently with the samples;
8. Collect non-aqueous samples to be analyzed for volatile organics using the following procedures:
i. USEPA Method 5035A, incorporated herein by reference, as amended and/or supplemented, found on the USEPAs website at
www.epa.gov/sam/method22.htm
; or
ii. Alternative procedures specified in a site specific QAPP;
9. Analyze all potable water samples as follows:
i. For volatile organic contaminants, use USEPA Method 524.2, incorporated herein by reference, in effect on the date of analysis, plus TICs (up to 15 organic compounds of greatest concentration which are not surrogates, internal standards, or targeted compounds listed under the method);
ii. For organic contaminants other than volatiles, analyze the samples for the non-volatile Target Compound List compounds, using the methods that meet the data quality objectives specified in the site specific QAPP, plus TICs (up to 15 organic compounds of greatest concentration which are not surrogates, internal standards, or targeted compounds listed under the method); and
iii. For inorganic contaminants, use the version of USEPA 200 series methods, incorporated herein by reference, in effect on the date of analysis. As an alternative, lead may be analyzed by the Standard Methods for the Examination of Water and Wastewater version of Method 3113B, incorporated herein by reference, in effect on the date of analysis;
10. When non-aqueous samples are taken for hexavalent chromium analysis:
i. Measure the pH and Eh of each sample and quality control sample, with the pH and Eh data included and plotted in the full data deliverables using the graph in USEPA SW-846 Method 3060A, incorporated herein by reference, as amended and supplemented; and
ii. Use a site sample for the quality control analyses so the reduction/oxidation effects of the site matrix can be properly evaluated using USEPA SW-846 Method 3060A;
11. If conventional analytical methods are not available or not suitable for a contaminant, then analysis of indicator parameters may be acceptable if accompanied by a technical rationale provided in the applicable phase report that is submitted to the Department (for example, pH may be used as an indicator parameter for acid or base discharges);
12. Follow all quality assurance/quality control procedures specified in the site specific QAPP;
13. Report, in the applicable remediation phase report submitted to the Department, all solid sample analysis results, including without limitation, soils and sediments, on a dry weight basis, except for those results required by the method to be otherwise reported;
14. Determine if either free product or residual product is present in any environmental media using direct observation, enhanced field observation methods, field instrumentation measurements, or laboratory analytical data;
i. For contaminants that are in their pure phase and are at standard state conditions (20 degrees Celsius to 25 degrees Celsius and one atmosphere pressure), and that have densities greater than water, free or residual product shall be considered to be present if the contaminant is detected in ground water at concentrations equal to or greater than one percent of the water solubility of the contaminant if ground water contains only that organic contaminant; or
ii. If a mixture of such contaminants is present, then the effective water solubility of the contaminant shall be estimated for this determination; and
15. Submit to the Department laboratory data deliverables, as listed in N.J.A.C. 7:26E Appendix A, with the applicable data deliverable form found on the Department's website at
www.nj.gov/dep/srp/srra/forms
, consistent with the following unless otherwise specifically required pursuant to an NJPDES permit:
i. Full laboratory data deliverables shall be submitted for all potable water, vapor intrusion (sub-slab, indoor and ambient), polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans sample analyses, and all hexavalent chromium soil sample analyses;
ii. Extractable petroleum hydrocarbon (EPH) deliverables shall be those defined in "Extractable Petroleum Hydrocarbons Methodology (Version 3.0), August 2010," as amended and/or supplemented (see
http://www.nj.gov/dep/srp/guidance/srra/eph_method.pdf
);
iii. Reduced laboratory data deliverables shall be submitted for all other analyses; and
iv. Upon request by the Department, the person responsible for conducting the remediation shall submit additional analytical information.
