Characterization

Multilevel Groundwater Monitoring Services

If you want to solve a three dimensional contaminant problem, you need to understand the three dimensional distribution of hydraulic head and contaminant concentrations. One of the problems faced by environmental scientists and engineers is that it is extremely expensive to collect subsurface data. As a result, these professionals are often tasked with characterizing a site to develop a conceptual model with a paucity of data. Furthermore, contaminant and hydraulic head measurements taken over large screened intervals may not provide useful information, if the predominant flow regimes and contaminant loading are in specific hydrogeologic units.

Passive, No-Purge Samplers Services

Groundwater characterization and remediation projects almost always include long-term groundwater monitoring programs. Most sites require sampling multiple wells from two to four times a year, which can become quite expensive. Traditional sampling methods entail purging three to five well volumes to collect formation groundwater samples. Low flow purging approaches remove less water but require detailed measurement and recording of purge parameter stabilization. With either purge method, you must containerize the contaminated groundwater and, in many cases, deal with it as hazardous waste.
