Sampling and conservation of volatile organic micropollutants in groundwater

Due to the growing concern for the environment the research on micropollutants in soil and groundwater increased. Specially the sampling and conservation of volatile organic micropollutants in groundwater, when the concentration is low (10–50 ug/1) has been showed critical. This paper deals with a test of a vacuumpump sampling procedure and the conservation of groundwatersamples under different temperature conditions. The research is carried out by TAUW Infra Consult B.V. by order of the Province of Zuid-Holland, the Netherlands.
