The ERDI Contaminated Water Operations Technician course certifies you to dive and work in contaminated water as a fully proficient member of a public safety team. You will master encapsulating dry suits and full-face masks, decontamination procedures, and the protocols that keep divers safe in polluted, hazardous, or biologically active environments.

This is the advanced contaminated-water proficiency level, built for working public safety divers.

Why train with Sink or Swim Scuba

You’ll train with an instructor who spent years as a working public safety diver and still supports local dive teams today. As an authorized Interspiro distributor, we keep rental and demo equipment on hand and offer on-site demo dives, so your team can try gear before investing — and we can assist with your dive operations as you build capability. ERDI training runs across three levels — Awareness, Operations, and Technician — and we train public safety divers locally, nationally, and internationally, including teams as far away as Spain.
