H.A.D., Inc. was contracted to drill and install monitoring wells inside a building with ceiling clearance ranging from 10 foot 6 inches to 14 foot. Holes ranged in size and depth from 2 inches to 4 inches from 50 to 150 foot. The job was proposed and started utilizing hollow stem augers. Augers were advanced to 120 feet deep, but crews were unable to install a well due to heaving material in the augers. The hollow stem auger plan was restructured and drilling was completed by mud rotary methods. Crews had to endure long house inside working in tight quarters with exceptionally limited overhead clearance. Most tools had to be brought into the building by hand. Crews had to adhere to strict health and safety guidelines and decontamination practices.

H.A.D., Inc. Performed services at an considerably high profile site in Northeast, Ohio. An excess of 200 borings were completed most being converted into monitoring wells. Access difficulties ranged from mostly wooded areas to wet muddy fields, to an extremely unstable lime lake. Both hollow stem augers and probe Geoprobe methods were utilized. All borings not converted to a well had to be tremmie grouted. Equipment had to be deconed and all wastes contained. Drilling had it difficulties ranging from extremely soft lime substances to drilling in the footprint of a large manufacturing facility. Concrete, rebar, piping, wood, scrap steel, train tracks, etc. Were all encountered. Site security and safety were paramount and all monitored very closely by the EPA and all parties involved.

H.A.D., Inc. Performed hollow stem augering and direct push services at an oil refinery located in Bradford, Pennsylvania. Services ranged from drilling in densely wooded terrain to drilling in a large tank farm. Many locations had to be accessed by lifting our drill rig 60 to 100 feet high and lowering the drill in-between one million gallon storage tanks. Crews received specific refinery safety/fire training to work on site. Crews endured severe temperatures while working in fire protective suits. Strict decon procedures were followed. Extreme care was taken hand clearing each hole to assure no product or utility lines were hit. During the course of a five year period HAD was the only drilling company continuously contacted for this work due to our professionalism, safety record, and on time delivery of services. Holes ranged in depth and size from 2" - 6" and 10 feet to 50 feet.

We were contracted to retrieve quite a length of rotosonic pipe that another driller had lost in the
hole. Our Barber DR24 drill rig was able to retrieve 480 feet of sonic drill pipe and save the job! Not only that, but we completed the job the first driller started by setting a 480-foot monitoring well with an eleven-foot section of well screen.

We were contracted to mobilize to Illinois to drill and install 21 soil vapor extraction (SVE) wells to depths of 15 to 20 feet below ground surface. H.A.D. field personnel installed specific screen lengths and slotted sizes at desired intervals depending upon what our client encountered at each location. Upon completion, wells were developed until water quality was satisfactory to our client. This project was completed in 6 days including travel time!

We mobilized a two man crew and a GeoProbe® 5400 to a residential area to retrieve water and soil samples. Crews also set 1-inch PVC monitoring wells. Operators worked under strict decontamination procedures. Level C equipment was on site in case conditions worsened. Due to the sensitivity of this location, work had to be performed during specific hours.

H.A.D., Inc. was contracted by SECOR International, on behalf of a mid-sized petroleum distributor, to inject oxygen release compound (ORC) into numerous borings to various depths. This services was performed at various locations throughout northeastern Ohio and West Virginia.

Completed 2-inch monitoring wells to 30 feet below grade in difficult heaving sand conditions. All field personnel obtained a security clearance. All well locations were in densely vegetated areas which made access difficult. We observed strict rules and regulations in addition to health and safety procedures. Decontamination was performed upon arrival, between each bore hole and prior to de-mobilization from the site.

Crews drilled and installed more than 20 two-inch diameter monitoring wells at a steel foundry. Drilling conditions included a difficult to penetrate slag and steel fill. Crews completed monitoring wells with flush-mounts and pro-casings each surrounded by 3-4 guard posts. To accommodate our customer's schedule, crews worked throughout the week, including Saturdays. In some instances the customer had both our CME-75 and our CME-85 working side by side.

Our CME-85 mobilized to this location and installed 6-inch casing. Immediately afterwards, our Ingersoll-Rand TH60 was mobilized to rock core. Crews averaged 100 feet per day of coring, providing the customer with a 3-inch diameter, 20-foot-long core. Crews cored at an average rate of 2 feet per minute.

Our EarthProbe 200® was mobilized to an oil refinery to install approximately 7- soil borings to 12 feet deep each. Samples were collected from various locations, including the dike walls surround aboveground oil storage tanks.
After our EarthProbe 200® work was completed, we mobilized a CME-85 and a skid-mounted CME-LC60. A 3-man drilling crew installed over 500 feet of four-inch diameter wells. Crews worked under strict decontamination procedures. A crane operator was on stand-by to lower the CME-LC60 into several tight access areas.

In the spring of 1999 H.A.D., Inc. mobilized a CME-85 to drill and install a deep monitoring well in heaving sands, and a track-mounted CME-LC60 to install various monitoring wells in the woods and other locations. Crews were required to mobilize through a creek to access one particular drilling location. Our REICHDrill T-690 was mobilized to drill exploratory borings approximately 460 feet in overburden on fluid, and our Bucyrus Erie 22-W Cable Tool Drill Rig was used to abandon a residential water well. H.A.D., Inc. had several pieces of equipment on site simultaneously to complete the work within the customer's time frame for the project, but Ohio's spring weather was not cooperative.

H.A.D., Inc. mobilized our CME-85 to this location for LaFarge Corporation, the world leader in aggregate products. Crews were drilling to 70 feet with the CME-85 continuous sampling tube system, providing the customer comprehensive samples with which to estimate aggregate reserves. We cased the overburden with our Ingersoll-Rand TH60 and cored limestone to determine the thickness and quality of the formation.

A CME-75® drill rig accompanied by a 3-man drill crew was mobilized to the site to drill and install a monitoring well to 285 feet in depth. The soil was sampled at five foot intervals and rock cores were taken to 285 feet. Specific permits were required and obtained by H.A.D., Inc. due to this drilling location. The drilling location was restored to its original condition by our crews.

We were contracted to drill and install a water well at an active gasoline station. The well was completed to a total depth of 147 feet below ground surface. Crews worked on this fast track project to comply with the client's need for water in addition to the EPA's requirements.

Our drilling crews worked in conjunction with Ohio Drilling Company in Delaware, Ohio, drilling 3 high-volume, large diameter water supply wells for the City of Delaware. The wells were 16 inches in diameter and 250 feet deep. Each well test-pumped at 1,500 gallons per minute in a dolomite formation with little draw down. This long-term project was completed successfully after months of drilling.

H.A.D., Inc. was contacted 48 hours before the school year was to begin. Crews worked around the clock to restore Waterloo Primary School's water supply. Field personnel worked in conjunction with the EPA and Waterloo School District.

H.A.D., Inc. was contracted to drill at an abandoned dump site in northwestern Pennsylvania. Because the contaminants were unknown and there were reports of former on-site workers being exposed to hazardous chemicals, H.A.D., Inc. was required to perform all drilling-related tasks in Level B PPE. Hollow stem augering, sampling, well installation, development, and decontamination were completed on-site in Level B PPE and incident-free. The scope of work was completed ahead of schedule despite the warm temperatures that placed crews under a great deal of stress. As an added measure of safety, H.A.D., Inc.'s senior driller and Health and Safety Officer were on the site. All customer information remains confidential.
