Total Petroleum Hydrocarbons, Reactive Cyanide, Reactive Sulfide, Ignitability, and Corrosivity

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.

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 total petroleum hydrocarbons, reactive cyanide, reactive sulfide, ignitability, or corrosivity. In addition, these are not drinking water test methods.

TEST ANALYSIS METHOD
Petroleum Hydrocarbons 418.1 (1)
Reactive Cyanide SW-846 7.3.3.2 (2)
Reactive Sulfide SW-846 7.3.4.1 (2)
Ignitability SW-846 7.1 or 1010, 1020 (2)
Corrosivity SW-846 7.2 or 9040, 9041, 9045 (2)
  1. U.S. Environmental Protection Agency (EPA). 1983 Test Methods for the Chemical Analysis of Water and Wastes. Washington, D.C. March.
  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 28 days for TPHC
Waste 8-oz wide mouth jar 1 8-oz jar none required
(ice preferred)
none (try not to exceed 28 days for cyanide)

MINIMUM LABORATORY QUALITY CONTROL MEASURES

The laboratory should have Standard Operating Procedures available for review for the total petroleum hydrocarbons, reactive cyanide, reactive sulfide, ignitability, and corrosivity, 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 a Laboratory Quality Assurance/Quality Control Statement available for review 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
Bank concentration should not exceed twice the instrument detection limit
Method Blank (does not apply to ignitability and corrosivity) Once per extraction set See method for allowable limits
Matrix Spikes (TPHC, reactive cyanide and reactive sulfide only) 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.
