Inventory of trace elements in groundwaters of the Netherlands

Abstract

An investigation of the Dutch groundwaters as for trace elements has been started. A sampling method has been developed. The results of the first measurements are given. They concern groundwaters from the East of the country as well as from the dune region. The investigation is handicapped by the fact that observation pits may be contaminated by rests of drilling fluid. Contrary to the first intention, production pits are also sampled now. The measurements will be extended to a complete sampling network.
