SOIL  &  GROUNDWATER  ASSESSMENT

SAMPLING +
MONITORING

Assessing environmental contaminants demands expertise and a thorough understanding of the specific contaminants in question, as well as their potential impacts on the environment. Soil and groundwater sampling and monitoring activities are often initiated by discoveries during storage tank removal activities and environmental site assessments (Phase I/II ESAs). Advanced Environmental Technologies (AET) will prepare a project specific site assessment scope of work that utilizes the site history and the known contaminants of concern.

These assessment activities aim to pinpoint the potential source area(s) of environmental impact to the soil and groundwater. This comprehensive evaluation involves the deployment of soil test borings and groundwater monitoring wells. Diverse drilling technologies are employed based on site-specific needs for installing soil borings. During the drilling process, soil samples are meticulously collected at specified locations and depth intervals. 

To expedite the identification of optimal soil samples for laboratory analysis, hand-held analyzers may be utilized in the field for on-site screening. Laboratory analyses are then carefully chosen, taking into account the known substances released and in compliance with regulatory requirements. Throughout the drilling activities, thorough field parameters and observations are documented. The information gathered is consolidated into detailed soil boring logs, which are subsequently incorporated into the comprehensive report documentation. This meticulous approach ensures a robust and accurate assessment of the environmental impact on both soil and groundwater.

The specific scope of work is contingent upon previous site assessment activities, the client's overarching objectives, and the historical context of the site. Soil and groundwater sampling and monitoring activities may include:

  • Site walkthroughs to map out locations of borings and monitoring wells.

  • Advancement of soil borings in specific site locations requiring further study.

  • Collection of soil samples for field screening and further laboratory analysis.

  • Soil sample analysis for volatile organic compounds (VOCs), benzene/toluene/ethylbenzene/xylenes (BTEX), methyl tertiary butyl ether (MTBE), semi volatile organic compounds (SVOCs), polynuclear aromatics (PNAs), total metals, pH, and dry weight. 

  • Installation of groundwater monitoring wells.

  • Development and surveying of the wells.

  • Collections of groundwater samples for laboratory analysis.

  • Reports summarizing field activities and analytical works such as a Phase II ESA or Subsurface Investigation Report.

Our approach to all environmental site investigations is unified by clear objectives. These objectives prioritize the gathering of essential data, minimizing mobilizations, and ensuring the delineation of impact extent. The dynamic nature of regulations frequently exacerbates the already challenging task of remediating stubborn contaminants in the subsurface area. Our collaborative approach involves closely partnering with clients to understand  their unique challenges. We actively support and advocate for them as they navigate the intricate regulatory landscapes that projects may confront. AET excels in delivering comprehensive site investigative services, covering a spectrum from minor contamination assessments to thorough remedial investigations, even in the complex context of Superfund sites. 

 

Our team of dedicated engineers and geologists provides expert guidance at every stage, developing precise characterization and diagnostic tools to enhance our clients' capacity to meet site-specific remedial action objectives efficiently, within a reasonable timeframe, and employing cost-effective solutions.
