Impact/Purpose:

Develop an analytical method for the analysis of phenols to better assess the occurrence of these compounds. The method should demonstrate good precision and accuracy, but be rugged enough and simple enough to be suitable for compliance monitoring if the need for regulation is determined. The critical target analytes are: 2-methyl phenol; 2,4-dichlorophenol; 2,4,6-trichlorophenol; and 2,4-dinitrophenol.

Description:

This project focused on the development of an analytical method for the analysis of phenols in drinking water. The need for this project is associated with the recently published Contaminant Candidate List (CCL). The following phenolic compounds are listed on the current CCL, and are described as needing analytical methods research and occurrence data: 2,4,6-trichlorophenol; 2,4-dichlorophenol; 2,4-dinitrophenol; and 2-methylphenol. From the currently available information, OW plans to propose linking compounds on the CCL with the upcoming Unregulated Contaminant Monitoring Rule (UCMR). Under the current time line proposed for this regulation, a method for the 4 phenols listed above was reviewed and published in 2000.

Project Information:

Progress :Research on this task has been completed. The analytical method procedure has been completed and method performance data including method detection limits (MDLs) have been generated. MDLs are < 0.58 ug/L for each of the 12 phenols included in the method. MDLs are <0.31 ug/L for the 4 phenols listed on the CCL. Accuracy is in the range of 70-130%, and precision approximately 5-10% RSD. The method was peer reviewed and delivered to the Office of Ground Water and Drinking Water (OGWDW) in June 2000 in time to be incorporated into the pending UCMR regulation.

Method:

Munch, J.W. Method 528. Determination of Phenols in Drinking Water by Solid Phase Extraction and Capillary Column Gas Chromatography/Mass Spectrometry (GC/MS), 4/00.

Relevance :Method 528 has been cited in the Unregulated Contaminant Monitoring Rule (66FR2273, Jan. 11, 2001) as the required methodology for nationwide monitoring of the phenols listed on the CCL.
