For example, they can be transformed into modern, green residential, retail or office spaces, with proper insulation, renewable energy and waste management systems. Investors, encouraged by both the adaptability and growing market interest, are increasingly willing to revitalize and modernize these sites. This is a beneficial process not only for business, but also for local communities, which gain new jobs, public spaces and improved urban aesthetics. However, it is crucial to conduct thorough geotechnical and environmental studies to ensure the safety and functionality of new developments.
When planning the construction of storage facilities, it is necessary to conduct soil and water studies, which include, at a minimum, the preparation of a geotechnical opinion. The scope of such an opinion is defined by law (Journal of Laws 2012, item 463). In addition, according to § 3 (1) (10) of this regulation, there is an obligation to carry out a risk analysis of contamination in the ground. It should be noted, however, that a risk analysis does not automatically mean performing a sozological study in each case. Only when the historical analysis indicates the risk of hazardous substances, it is necessary to carry out an assessment of the contamination of the earth's surface in accordance with the Regulation of the Minister of the Environment of September 1, 2016. (Journal of Laws 2016 item 1395). The purpose of environmental screening is to identify contaminants in order to then plan the remediation process accordingly. At the initial stage of the analysis, environmental screening is recommended to detect contaminants quickly and cost-effectively without the need for expensive laboratory analysis.
Modern screening techniques using geoenvironmental probes allow real-time detection of contaminants at the full depth of the soil profile. Among others, MIP (Membrane Interface Probe) probes are available for the detection of hydrocarbon products, chlorinated volatile organic compounds, and OIP (Optical Image Profiler) probes for organic liquids such as fuels, oils or tars. If the results of preliminary tests indicate the need for a detailed sozological diagnosis, it is necessary to perform thorough analyses in accredited laboratories. The quality of soil, water or ground air sampling is crucial, as mistakes at this stage can affect erroneous assessment of the degree of environmental contamination and remediation decisions. The direct push drilling technique allows for high-quality sampling by pushing a thin-walled sampler into the ground and protecting the samples from secondary contamination when pulled out of the hole, minimizing the risk of errors. Proper sampling techniques are essential for accurate and undisturbed results. Combining sozological and geotechnical surveys brings significant benefits to investors. Time and cost savings resulting from properly conducted studies enable better planning and implementation of investments. This makes the process of cleaning up the ground and building modern warehouses more efficient and safer.
Increased environmental awareness and the development of modern testing methods make investing in brownfields more attractive and profitable. Thanks to reliable land surveys, investors can safely plan and implement their projects, contributing to the revitalization and development of post-industrial sites in Poland.
