In the late 1950s members of the water well industry came together to create a trade show specifically for the Pacific Northwest. As the event grew in popularity the Pacific Northwest Ground Water Association (PNWGWA) was offically formed with representation from Alaska, Idaho, Oregon, and Washington state associations.

The PNWGWA's goal is to provide a quality program bringing together contractors, manufacturers, and suppliers focused on the needs of the ground water industry in the Pacific Northwest. The Pacific Northwest Ground Water Expo is your show and the PNWGWA board members welcome your suggestions to make it even bigger and better.

Join your fellow ground water industry professionals from Alaska, Idaho, Oregon, Washington, and surrounding areas for the premier biennial industry event in the region.
