This former filling station was converted to a popular local restaurant after removal of gasoline UST’s. The groundwater contamination plume at this site extended some 800′ from the source area. After assessment was complete an air sparge/soil vapor extraction systems was installed. After two years of operation an estimated of 3,000 pounds of petroleum contamination was removed.

This is an example of a monitoring well constructed by JSA. At this site we are checking water levels while continuously monitoring other parameters with a data logging probe. JSA’s in-house drill crews install monitoring wells ranging from ¾ inches to 12 inches in diameter utilizing direct push, hollow stem auger, and rotary methodologies.

The City of Live Oak’s current wastewater treatment plant is a biological secondary treatment facility using a Modified Ludzack-Ettinger process with 1.5 MGD capacity and high-level disinfection. JSA was selected to upgrade the system to handle a capacity of 3.0 MGD and complete the complex permitting process.

This is a 2,000 gallon hydro-pneumatic tank that was installed for one of our clients. The system is self sustaining with separate chlorination system, air system, and well system. The system was installed and fully operational with-in 2 days time. All permitting for installation and consumptive use were included.

This is a 3 Dimensional model that was created using AutoCAD Civil 3D. This model was created to give a visual model to show the direction of travel of a contamination plume in relation to supply well located close to the source. In some applications it may be necessary to use this type of modeling to design. This model shows contamination below and above the water level.

The Failing F-7 Rig has the ability to do both mud rotary and hollow stem auger drilling. This rig has the ability to install wells up to 1,000 feet with a diameter of up to 12 inch. This rig is used for our larger jobs and is used for monitoring well installations.

The Mobil B61 HD rig has the ability to do both hollow stem auger and mud rotary drilling. With the ability to install wells up to 8” in diameter. This is our medium sized rig and is also used for monitoring well installation. This is a very reliable rig and has been in service for many years with minimal down time.

The AMS 9600 Pro Power Probe is mounted on a truck for mobility. This set-up gives us the ability to perform direct push drilling to a depth of 100 feet even in heavy clays. This rig also has the ability to drill using hollow stem augers of 4-1/4” for installing 2” monitoring wells. For some applications it may be required for the use of split-spoon sampling to be performed, this rig can perform this with a 140 lb percussion hammer.

The AMS 9100 VTR D Power Probe is a track mounted probe with the ability to fit through a door way for sites where drilling must be performed inside a building. The rig uses direct push drilling up to a depth of 45 feet. This is our smallest and new rig and has been a major cost cutter on certain sites where indoor drilling is required.
