The Basics of Baseline Hydrogeological Assessments

A baseline hydrogeological assessment is an important part of the process of assessing and managing groundwater resources. It provides a comprehensive overview of the hydrogeology of an area, including information on geological features, hydrological processes, groundwater levels, and water quality. Azure Group specialized in conducting baseline hydrogeological assessments that are tailored to meet the specific requirements of each project. Azure Group’s comprehensive baseline hydrogeological assessment typically includes detailed field investigations, including geophysical surveys and borehole drilling; Analysis of geological and hydrological characteristics, such as water-bearing formations, stratigraphy

In this blog post, we’ll take a look at what goes into a baseline hydrogeological assessment and why it is so important.


What Does a Baseline Hydrogeological Assessment Do?

A baseline hydrogeological assessment involves collecting data on the physical characteristics of an area’s subsurface environment. This includes such things as aquifers, surface water features, geologic structure, hydro stratigraphy (the arrangement of layers in the subsurface), and other information related to hydrology. The collected data is then used to model the area’s groundwater system and assess its vulnerability to human activities.


Why Is a Baseline Hydrogeological Assessment Important?

Baseline hydrogeological assessments are essential for understanding how human activities can affect groundwater resources. By providing detailed information about the subsurface environment, these assessments can help to identify potential risks from activities such as land use change or pollutant introductions. They can also be used to develop management plans that reduce or mitigate those risks. The assessment also serves as an important starting point for monitoring changes in the subsurface environment over time.


How Is a Baseline Hydrogeological Assessment Conducted?

Baseline hydrogeological assessments typically involve mapping geological features and collecting core samples from boreholes drilled in the field. These core samples provide information on the properties of soils and rocks at various depths below ground level. Other methods such as seismic surveys or electrical resistivity imaging may also be used to map subsurface features in greater detail. Groundwater samples can also be taken to assess water quality at various points throughout an aquifer system.


Baseline hydrogeological assessments are critical for understanding how human activities affect groundwater resources. By providing comprehensive data about the subsurface environment, these assessments help identify potential risks from activities such as land-use change or pollutant introductions and allow us to develop strategies for mitigating those risks. For anyone involved in managing groundwater resources, having an accurate baseline assessment is essential for making sound decisions about how best to protect these valuable resources for future generations.
