Phase 2 Environmental InvestigationsFollowing discovery of sub-surface contamination, regulators will request a Work Plan for delineating the extent of the contaminants. This involves a precise study of previous site use to determine optimum locations for soil borings. Borings are drilled and sampled to determine the depth and the width of the contaminant plume. Depending on the sampling results, groundwater monitoring wells will be installed. Throughout this process, controlling costs for the property owner is a top priority.

Monitoring Wells

Phase 2 Environmental InvestigationsEarthSafe can install and perform requested groundwater monitoring as mandated by a regulatory agency or for geotechnical purposes. Sampling techniques include purge or non-purge protocol following measuring depth to water, total depth of the well and sediment accumulation. Other measurements include purge volume calculations and physical parameters of the groundwater (pH, Turbidity, Temperature, etc). Depending on site conditions, some regulators will request USEPA Low-Flow-Micropurge sampling.

Groundwater Monitoring Well Abandonment

Upon Regulatory Closure of a site with monitoring wells, the wells are required to be destroyed. This is necessary to prevent future, outside contaminants to drain into the well. EarthSafe will remove the upper well casing, pressure fill and seal abandoned wells complying with the Water Code requirements set by the State and local jurisdictions. Well Completion Reports are submitted to the Department of Water Resources.
