The National Drilling Association is a nonprofit trade association of contractors, manufacturers and affiliated members from the drilling industry representing the geotechnical, environmental and mineral exploration sectors of this industry. The NDA mission is to promote the use of professional drilling contractors and their methods.

NDA Safety Award Program

The program allows drilling contractors of similar size to compete for an award based on their incident rates. Safety Award recipients will be honored, each year, at the NDA Annual Convention.

Why I belong to the National Drilling Association:

"NDA member Tom Brown hired us for a large job in DC and Connelly & Assoc., also an NDA member, provided us a licensed driller for a job we had in Delaware. (We had lost the services of our NY/NJ/DE licensed driller to a stroke.) In addition I have quoted a couple large jobs to Jim Howe of Geotechnology that haven't materialized, but we've been trying to team. We also sold a truck to Geotechnology. So it's not just a meeting of peers-being a member of NDA offers promotion of the Geotechnical and Environmental drilling industry as well as teaming or prime/sub opportunities with other member firms."
