Incremental Sampling Methodology: <\/span><\/h1>\n

An area-wide sampling of military training facilities at Tr\u00dcbPl J\u00e4gerbr\u00fcck<\/span><\/h1>\n

<\/h2>\n

Mull & Partner Ingenieurgesellschaft mbH has been working for many years on projects for the Lower Saxony State Office for Building and Real Estate (NLBL) in the field of contaminated site management as well as pre- and post-care soil and water protection for the German Federal Armed Forces. Particularly when carrying out soil investigations on large suspected sites with unclear contamination foci such as firing ranges and target areas, the question of efficient, area-wide and, above all, representative soil sampling arises.<\/p>\n

Initiated by the Federal Ministry of Defence (BMVg) and organised by the NLBL, the Incremental Sampling Methodology (ISM) is to be tested as a possible soil sampling procedure, based on the above question. The ISM was developed by the Interstate Technology and Regulatory Council (ITRC) in the USA and is a sampling procedure to produce composite samples. This procedure reduces data variability and provides a largely unbiased estimate of mean pollutant concentrations for a defined soil volume.<\/p>\n

Based on the Incremental Sampling Methodology (ISM), Mull & Partner Ingenieurgesellschaft mbH has produced a sampling device for the ISM on behalf of the NLBL. The core of the sampling device is a sampling cylinder (d = 5 cm, h = 10 cm), which can be emptied again via a simple sliding mechanism (see Figure 1).<\/p>\n

In the period from 13.07. - 17.07.2020, the device was used for the first time on various training facilities (firing ranges, hand grenade throwing and blasting range) at Tr\u00dcbPl J\u00e4gerbr\u00fcck in Torgelow, Mecklenburg-Western Pomerania.<\/p>\n

For the soil sampling, soil samples were taken within defined investigation areas (decision units) in previously defined steps (in so-called increments) and on different sampling paths (cf. also Figure 4). The sizes of the decision units varied between 102 and 2,208 m\u00b2 depending on the use of the exercise facilities. The distances between the increments were between 2 and 4 m. Following sampling, the sample material was homogenised and a composite sample with a mass of approx. 2 kg was prepared for each sampling path.<\/p>\n

At present, the samples are analysed in the laboratory for use-specific heavy metals and compounds typical of explosives, both in the solid and in the eluate (2:1 column eluate).<\/p>\n

This study methodology is intended to provide a reproducible and representative inventory (actual state) of the military training area to be assessed.\u00a0<\/span><\/p>\n
