Groundwater Monitoring Network Design and Installation


 

The CCR Rule requires that the groundwater monitoring system for each CCR unit includes a minimum of one (1) upgradient/background monitoring well to accurately represent the quality of groundwater that has not been affected by leakage from the CCR unit. Additionally, the CCR Rule requires a minimum of three (3) downgradient monitoring wells to accurately represent the quality of groundwater passing the waste boundary of the CCR unit.  The monitoring wells must be installed at appropriate locations and depths to yield groundwater samples from the uppermost aquifer as close as practicable to the boundary of the CCR unit.

AGES has successfully designed and installed CCR groundwater monitoring networks for several CCR units operated by major utilities.  AGES reviewed available information for existing wells and piezometers to evaluate hydrogeologic conditions, conducted soil borings at each unit to obtain specific geologic data (such as lithology, depth to water and characteristics of the uppermost aquifer) and collected samples for grain-size analysis to aid in the design of the groundwater monitoring network.

AGES used data gathered during the review of existing information and from the soil borings to design and install the groundwater monitoring systems to comply with the CCR Rule requirements. Because field filtering of groundwater samples is not allowed under the CCR Program, AGES used the grain size analysis results to aid in the design of pre-packed well screens for each CCR unit, which allowed for the collection of groundwater samples with consistently low (less than 5 NTUs) turbidity without field filtering.
