Services"},"content":{"rendered":"<p>AES utilizes the following technologies to identify, delineate, and monitor impacts to the soil, groundwater, surface water, and sediment.\u00a0 AES is experienced with a large variety of contaminated sites impacted by historic fill, dry-cleaning chlorinated solvents (cVOCs), gasoline, heating oils, diesel fuel, waste oil, Polychlorinated Biphenyls (PCBs), pesticides, herbicides, metals, plasticizers, Polycyclic Aromatic Hydrocarbons (PAHs), and others.\u00a0 Some remedial investigation technologies utilized by AES are described below:<\/p>\n<p><strong>Geophysical Survey<\/strong><\/p>\n<p>AES may perform a geophysical survey, which includes Ground Penetrating Radar (GPR) and magnetometer (metal detector) scans to identify possible Underground Storage Tanks (USTs), piping, and other subsurface features.<\/p>\n<p><strong>Soil Boring Sampling<\/strong><\/p>\n<p>Soil cores are collected by direct push or split-spoons and removed from the ground to be screened and samples collected.<\/p>\n<p><strong>Test Pit Sampling<\/strong><\/p>\n<p>A test pit in soil or weathered bedrock is performed by equipment, which varies in size from a hand shovel to an excavator in order to remove soils to screen the strata and collect samples.<\/p>\n<p><strong>Temporary Well Point Installations<\/strong><\/p>\n<p>A short-term alternative to permanent monitoring wells are temporary well points.\u00a0 Temporary well points are installed into soil borings and are typically a smaller diameter than permanent wells.\u00a0\u00a0 Temporary well points can be sampled the same day as installation, but must be removed in 48-hours.\u00a0 Therefore, they are not typically used for long term monitoring.<\/p>\n<p><strong>Monitoring Well Installations<\/strong><\/p>\n<p>In order to monitor and treat groundwater impacts, AES mayinstall permanent monitoring wells utilizing a variety of technologies and drill rigs of all sizes based on site constraints.\u00a0 Monitoring well installation technologies include:<\/p>\n<ul>\n<li><strong>Direct Push &#8211; <\/strong>A borehole is made in soils using an expendable point.\u00a0 The well screen and casing are installed and then the tooling is removed.\u00a0 This method is typically used for shallow wells.<\/li>\n<li><strong>Hollow Stem Augers &#8211;<\/strong>\u00a0 Sections of hollow stem augers are corkscrewed into soils with an expendable point.\u00a0 The well screen and casing are placed inside the augers and then the tooling is removed.\u00a0 This method is typically used for shallow wells.<\/li>\n<li><strong>Air Rotary &#8211;<\/strong>\u00a0 Compressed air lifts and drops a down-hole hammering drill bit.\u00a0 The soil or bedrock cuttings are then lifted out of the borehole to the surface by the air.\u00a0 This method is typically used for deep wells and bedrock wells.<\/li>\n<li><strong>Rock Coring &#8211;<\/strong>\u00a0 Rock cores are cut using a rotating barrel with a diamond edged blade that is water cooled.\u00a0 Cores are brought to the surface using cables.<\/li>\n<li><strong>Mud Rotary &#8211;<\/strong>\u00a0 Mud rotary uses a rotating drill bit with teeth to cut into soils.\u00a0 Mud is pumped though the drill bit to push out soils and keep the borehole open by using water pressure against the formation.\u00a0 This method is typically used for deep wells in unconsolidated (not bedrock) material.<\/li>\n<li><strong>Sonic Drilling &#8211;<\/strong>\u00a0 Sonic drilling uses rapid vibrations to break up soil and rock.\u00a0 Water is delivered to the drill bit to push soil and rock cuttings out of the borehole.\u00a0 This method is used for shallow and deep wells in soil or bedrock.<\/li>\n<\/ul>\n<p><img loading=\"lazy\"
