The primary method of geological investigation in environmental studies is site assessment and characterization, which includes soil and water sampling. This approach is fundamental because it provides direct data about the conditions and properties of the site in question, allowing for an accurate evaluation of potential environmental impacts, contamination levels, and suitability for various uses.

Soil and water sampling specifically enable researchers to analyze the composition and quality of these materials, which are critical for understanding local geology and hydrology. This data informs decisions regarding land use, remediation efforts, and the management of natural resources. The emphasis on direct sampling helps ensure that the conclusions drawn are grounded in actual field data rather than theoretical models or remote observations.

While geological mapping using satellite images, modeling formations with 3D software, and conducting general surveys can contribute valuable insights, they are typically supplementary to the more hands-on approach of site assessment. These methods often rely on existing data or models that may not capture the unique conditions present at a specific site. Hence, site assessment and characterization remain the cornerstone of geological investigations in the context of environmental studies.
