The inventive method is designed to test contaminants in soil that is contaminated with petroleum related products. The method involves the use of a container that will separate soil into a head space for analysis. The container consists of two halves and the container is partially filled with a soiled dirt specimen. The container is then hermetically sealed against the environment by way of a cover snapped over the container rim. The container with the contaminated specimen therein is allowed to accumulate a vapor head space within a certain time period. An instrument will puncture a sealed orifice in the top cover and a sample of the vapor is withdrawn for further analysis. |
