DESCRIPTION OF METHODS 

Pesticides (Method E525.2 - Drinking Water List)

Sampling: 2-1000 mL glass bottles preserved with hydrochloric acid (large blue capped ampule) to a pH <2. 

Residual chlorine is reduced in the sample by the addition of 40-50 mg of sodium sulfite. Mix well to 

insure it is dissolved in the sample. It is very important that the sample be dechlorinated prior to adding 

acid to lower the pH. Store at6°C.

Holding Time: 14 days to extraction; 30 days to analysis.

Method: January 1998 Massachusetts method as modified by Montana DEQ 

Sampling: Water: 2-1000 mL glass bottles preserved with sulfuric acid. Store at6°C.

Soils: 125 mL glass jar. Store at6°C.

Holding Time: 14(water) or 7(soil) days to extraction; 40 days to analysis

Soil: 20 mg/Kg as total extractable hydrocarbons

Notes: EPH screening: Samples that contain 50 mg/Kg for soil or 1000 μg/L for water will require 

EPH aromatic/aliphatic fractionation and MBTEX analysis. The need for PAH analysis on 

these samples will be determined by the MDEQ case manager on a case by case basis.

MBTEX will be performed by Method SW 8021B or SW 8260B. PAH analysis on soil 

extracts may be analyzed by GC-FID. On waters, PAHs are analyzed using Method SW 

8270C. PAH hits must be confirmed by second column analysis or GC-MS.
