METHOD 9060A TOTAL ORGANIC CARBON - US EPA

TOTAL ORGANIC CARBON 1.0 SCOPE AND APPLICATION 1.1 This method is used to determine the concentration of organic carbon in ground water, surface and saline waters, and domestic and industrial wastes. Some restrictions are noted in Secs. 2.0 and 3.0. 1.2 This method is most applicable to measurement of organic carbon above 1 mg/L. 2.0 SUMMARY OF

Volatile Organic Compounds in Soil – PBM

Weigh field methanol preserved sample vials at the laboratory to at least the nearest 0.01 grams. Determine the accurate weight of wet soil or solids in each sample from the weight (vial + methanol + soil sample) minus the pre-weight (vial + methanol). Prior to weighing, carefully clean the outside of the sample vials to remove any adhered soil

Collecting Soil Samples for VOC Analysis - En Novative Tech

Managing sampling from a soil core can be a complex situation - stability of VOCs in the core depends on factors such as: 1. whether the soil is consolidated (e.g., clay, till) or unconsolidated (e.g., sand, gravel) 2. time that the core is open or exposed before sampling (off-gassing) 3. moisture content of the soil

gently to reduce agitation which might drive off volatile compounds. In general, liquid samples should be poured into the vial without introducing any air bubbles within the vial as it is being filled. Should bubbling occur as a result of violent pouring, the sample must be poured out and the vial refilled. The vials should be

USEPA REGION 9 TECHNICAL GUIDELINES FOR ACCURATELY

With the knowledge that

Total Organic Carbon (TOC) - Water Quality Parameter Overview

Total organic carbon is a measure of the amount of organic compounds contained in a water sample. Organic carbon-containing compounds can either be dissolved in water or exist in water as undissolved, suspended material, or liquid. This organic matter can enter water naturally and through man-made sources/processes.

VOC Guidelines - USGS

Wearing vinyl gloves, lower a 40-mL vial to about one half of the stream depth. Point the vial into the stream current, remove the cap, allow the vial to fill, then slowly bring it to the surface. Add hydrochloric acid (HCL), carefully cap the vial, and check for air bubbles that may be trapped in the vial.

Total Organic Carbon (TOC / Foc) in Soil/Sediment by

Foc is the Fraction of Organic Carbon in a soil, which is simply its Total Organic Carbon content expressed as a decimal fraction (e.g. 1.0% TOC = 0.010 Foc). Method Summary A small sub-sample of a dried, ground soil sample is mixed with catalyst or accelerators

SOIL AND SEDIMENT SAMPLING METHODS | Science Inventory | US EPA

Among the high priority research areas were the needs for: (1) standard soil sampling and sample preparation methods and (2) a standard bulk sample (e.g., soil, asbestos containing materials, etc.) grinding technique. The objective of this research effort is to evaluate (and develop, if necessary) a method for the effective and efficient

COMPOSITE SAMPLING FOR SOIL VOC ANALYSIS - U.S EPA Web Server

Jun 06, 2005 · To explore the feasibility of composite sampling for soil VOC analysis, core samples were collected and cut into sections at 20, 30, 40, 50, 60, 70 and 80 cm below the ground surface. After each cut, approximately 5 g of soil was removed from the newly exposed surface (top end of the cut) using a truncated syringe and placed in a preweighed 40
