Porewater Sampling

Pore water sampling is commonly used in various environmental and geotechnical studies. It provides insights into groundwater quality, the transport and fate of contaminants, nutrient cycling, and biogeochemical processes occurring in the subsurface. The collected pore water samples can be analyzed for various parameters, including pH, conductivity, dissolved oxygen, nutrients, heavy metals, organic compounds, and microbial activity.

This technique is particularly useful in assessing the impact of human activities on groundwater systems and identifying potential sources of contamination. It can aid in evaluating the effectiveness of remediation efforts, monitoring the migration of pollutants, and understanding the natural processes that influence groundwater quality.

Pore water sampling techniques vary depending on the specific objectives of the study and the characteristics of the site. Common methods include suction lysimeters, pore water equilibrators, or the use of centrifugation to extract the water from the pore spaces. The collected samples are then typically analyzed in a laboratory using various analytical techniques to measure the desired parameters.
