Nitroaromatics and Nitroglycerine

This Fact Sheet is presented by the U. S. Environmental Protection Agency, Region III (EPA) to assist in the selection of analytical parameters and the associated Quality Assurance and Quality Control (QA/QC) procedures to be utilized in Phase II Environmental Assessments under the U.S. Environmental Protection Agency (EPA) Brownfields initiative. This fact sheet is presented for informational purposes only, and should not be construed as a federal policy or directive. The Brownfields Coordinator for this region may be reached at 215-814-5000.

Nitroaromatic compounds are compounds usually associated with explosive manufacturing and ordnance facilities. Nitroaromatic compounds include TNT, DNT, RDX, and HMX.

ANALYSIS METHODS

Please note that the methods listed below are EPA approved and the most commonly used by EPA and their contractors. However, they are not the only methods for the analysis of nitroaromatics and nitroglycerine. In addition, these are not drinking water test methods.

TEST ANALYSIS METHOD
Nitroaromatics 8090, 8330 (2), or 609 (1)
Nitroglycerine 8332 (2)
  1. U.S. Environmental Protection Agency (EPA). 1992. Test Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater. Washington, D.C. July.
  2. EPA. 1986. Test Methods for Evaluating Solid Waste. SW-846. Washington, D.C. September.

COLLECTION MEDIA/VOLUME

Listed below are the EPA-recommended preservation and holding times as well as suggested glassware.

MATRIX GLASSWARE VOLUME PRESERVATIVE HOLDING TIME
Soil/Sediment 8-oz soil jar 1 8-oz jar ice to 4º C 7 days
Water 32-oz amber bottle 1 32-oz bottle ice to 4º C 7 days

The laboratory should have Standard Operating Procedures available for review for the nitroaromatics and nitroglycerine analyses and for all associated methods needed to complete these analyses, such as total solids, instrument maintenance, sample handling, and sample documentation procedures. In addition, the laboratory should have available for review a Laboratory Quality Assurance/Quality Control Statement which includes all key personnel qualifications.

QC TYPE FREQUENCY OF ANALYSIS ACCEPTABLE LIMITS
Initial Calibration Prior to analysis of samples (minimum three concentration levels for every compound and an instrument blank) Correlation Coefficient for all analyses should be >0.995, blank concentration should not exceed twice the instrument detection limit
Continuing Calibration Once per 10 samples (mid-level standard containing all compounds) and a continuing calibration blank Within 10% of true value
Blank concentration should not exceed twice the instrument detection limit
Method Blank Once per extraction set See method for allowable limits
Matrix Spikes One per set or per 20 samples 75-125%
Duplicates One per set or per 20 samples  

MINIMUM DATA PACKAGE REQUIREMENTS

Note: The optional QC must be maintained by laboratory for at least one year for possible future QC audits.
