Groundwater Monitoring, Collection & Analysis

The world relies on groundwater, which is why there are many monitoring requirements in place by the Bureau of Safe Drinking Water. CWM has experience in the five basic types of groundwater monitoring: Ambient, Compliance, Assessment, Remediation, and Post-Closure Monitoring.

CWM Environmental field and laboratory technicians from both our Cleveland location and Kittanning location are equipped with the knowledge and expertise necessary to satisfy groundwater monitoring requirements compliant with state and federal government regulatory standards. Our Kittanning laboratory is certified under the Pennsylvania Department of Environmental Protection, and is NELAP accredited for drinking water.

Representative and comparable analytical data and detailed records for groundwater or surface water monitoring programs are dependent on consistent and reliable sampling methods, detailed observations and analytical techniques. Our groundwater technicians maintain field logbooks for each sampling point, record test data, prepare reports, summaries, and/or charts that interpret test results.

CWM technicians test wells drilled at various depths and locations to reflect different strata of groundwater at customer sites. Once the volume of the well is known, the groundwater is purged from the well with dedicated Grundfos pumps, non-dedicated pump and reels, micro purge bladder pumps and manual bailers. This process takes place to clear the well of stagnant water, allowing it to recharge with fresh water. Two to three volumes of water are purged to allow for a representative sample and parameters are measured until stable (pH, conductivity, turbidity, ORP and temperature).

Who Needs Groundwater Monitoring?

  • Landfills - Landfills receiving more than 20 tons of solid waste per day are required to monitor underlying groundwater during active life and post-closure for 62 constituents listed in 40 CFR part 258.
  • Coal Ash DepositsCoal ash disposal units must be monitored around the surface impounds and landfills.The EPA now requires CCR units to install monitoring well systems to detect the presence of hazardous constituents and other parameters such as pH and total dissolved solids
  • Power Plants - Electric utilities that generate over 110 million tons of CCRs with 60 percent being disposed of in landfills and surface impounds.
  • Oil & Gas Drilling Whether you are drilling or have a company drilling near your home, you should have pre-drilling and post-drilling testing to protect yourself.

Each technician follows a quality control plan to ensure that proper field calibration, sampling, transporting, analytical and documentation procedures are followed.
