Hydrogeological Assessments: What Do They Involve?

Hydrogeologists carry out extensive field surveys and lab studies to examine water resource properties and manage these resources. Also, hydrogeological assessments are carried out to evaluate possible wastewater alternatives, mitigate wetlands, and develop water supply. Hydrogeological assessments can be related to the following:

Developing Water Supplies

Often, projects focused on water supply developments include performing sanitary surveys, calculating wellhead protection zones, fracture tracing, supervising the construction of water wells, and hydrological testing. Also, facilities coordinate sampling of new source and perform Microscopic Particulate Analysis. The installation of new water supply systems typically includes groundwater under the influence. It includes site assessment and composite sample collection.

Monitoring Water Quality in Real-Time

Etude hydrologique services providers can offer technical assistance in sitting, retrieving data, testing, and testing water quality. They will determine how the changes in water quality can be associated with other data like phosphate, fecal coliform, and total suspended solids.

Evaluating Wastewater Disposal

Typically, this process includes a combination of hydrological and soil assessments to identity the best wastewater disposal system that can be used for commercial or domestic waste. It includes evaluating available geologic data and soil, carrying out on-site testing, assessing the characteristics of wastewater, as well as reviewing local and state regulations.

Investigating the Soil

A wastewater evaluation won’t be complete without investigating the soil. The investigation includes reviewing available soil surveys, as well as performing permeability testing, on-site soil testing evaluations, and infiltration capacity testing. This process is meant to determine soil characteristics and potential limitations to wastewater disposal.

Evaluating Spray Irrigation Systems

This is performed by investigating the soil and performing preliminary hydrological assessments.  During such evaluations, engineers will use on-site soil testing and available meteorological data to establish a site-specific budget. A hydrological evaluation must be performed to come up with an estimate of vegetation nitrogen uptake and identify possible effects on groundwater and the quality of surface water.

Installing Monitoring Wells

During this process, hydrogeologists assist in installing, designing, and testing monitoring wells. During the design stage of the process, testing drilling is performed to get aquifer samples. Then, the gravel pack and screen size are sized. Typically, during installation, assessment experts will oversee the on-site drilling, testing, development, and construction of a well.

Mitigating Wetlands

For projects such as wetland mitigation, hydrogeologists will assist in assessing the soil and hydrological conditions, set up budgets, and determine the water table’s depth and nature. Also, they can monitor and design wetland treatment systems for stormwater runoff, acid mine drainage, wastewater treatment, and other applications.
