PCBs as Decachlorobiphenyl – Drinking Water
Laboratory Fee Schedule
Procedure: EZZ0082A
PCBs as Decachlorobiphenyl – Drinking Water
Synonym(s): | PCBs as Decachloribiphenyl in Water |
Requisition Form | G-22 |
Test Description |
PCB SOC6 EPA method 508A: Determination of total polychlorinated biphenyls as Decachlorobiphenyl equivalent in drinking water. |
Pre-Approval Needed | N/A |
Supplemental Information Required | Measure and record the chlorine residual |
Supplemental Form(s) | N/A |
Performed on Specimens from (sources) | Environmental |
Sample/Specimen Type for Testing | Drinking Water |
Minimum Volume/Size Required | Collect triplicate (3) samples. Narrow-mouth amber glass bottle with Teflon (PTFE) cap liner; 1 quart (1 L) |
Storage/Preservation Prior to Shipping |
|
Transport Medium | N/A |
Specimen Labeling |
|
Shipping and Specimen Handling Requirements |
|
Method | EPA 508A |
Turn-around Time | Samples must be extracted by the lab within 14 days of collection. |
Interferences/Limitations |
Collection containers should be meticulously cleaned. Matrix interferences may be caused by contaminants that are coextracted from the sample. The extent of matrix interferences may vary considerably from sample to sample. This method is prone to false positives. In addition to PCBs, several compounds and classes of compounds will form DCB with varying yields when extracted and perchlorinated according to this procedure. Based upon a literature search such compounds include biphenyl, polyhalogenated biphenyls, hydrogenated biphenyls, and polyhalogenated terphenyls. If such compounds are present in the extract, false positive or positively biased data will be generated. |
Common Causes for Rejection | Insufficient quantity, unacceptable specimen type or source, improper shipping conditions, expired media or collection container, discrepancies between specimen label and submission form, and/or incomplete or missing submission form |
Additional Information |
This sample is collected for confirmation when an Aroclor is detected by screening method 508.1. Contact laboratory in advance to see if reagents are available for testing due to high method blanks. Contact the laboratory at (512) 776-7587 for currently supported analyte list. |
