    The paper presents the results of optimization of sampling depth for soil gas applied in the surface geochemical survey. The studies were carried out in two areas: the Wałbrzych Trough and the Karlino area (Western Pomerania). The studies in the Wałbrzych The paper presents the results of optimization of sampling depth for soil gas applied in the surface geochemical survey. The studies were carried out in two areas: the Wałbrzych Trough and the Karlino area (Western Pomerania). The studies in the Wałbrzych Trough was carried out over the closed and remediated coal mines. The results demonstrated that sampling depth interval 1.0-1.8 meters is an optimum for surface geochemical survey as it is located beneath the active exchange zone (i.e. beneath 1.0 meter) but provides distinct geochemical response from deep sources. The studies in the Karlino area (Western Pomerania) was carried out over oil and gas pools. It was found that 1.2 meter depth is an optimum for geochemical sampling with the »free« gas method in this area. The some sampling depth can be apply on in the Wałbrzych Trough. Such studies must be passed in other areas of Poland to confirm this depth of sampling.
