Removing weapons of war and restoring our oceans

Who we Are

Our Story

Platinum East was founded by a small team of highly talented U.S. Navy EOD technicians to help communities recover from environmental contamination left in the devastating wake of war. We aim to reduce the catastrophic impact that explosive remnants of war create around the world. By helping developing nations leverage a consortium of state and community level support, we promote environmental restoration and the protection of lives.

Our team has a combined 150 years of military, government, and academic service and has disposed of more than 1.5 million pounds of explosive remnants of war. We are determined to do our part in restoring our oceans and renewing our communities.

Dr. CJ Cowlin

Founder, Chairman, and Chief Executive Officer

The common thread in the uncommon life of CJ Cowlin is engaged altruism. From bomb disposal to medicine, he believes service to humanity is essential to a meaningful life. Growing up in unremarkable rural New York circumstances, the universe gifted him a career in US Navy Explosive Ordnance Disposal (EOD) circa 1980. After his initial stint in the Navy, he went on a 15 year international academic walkabout…from Corporate Japan, Commercial Diving, and global university faculties; he helped people. After inadvertently earning a plethora of graduate degrees, 9/11 happened, and he was back in the Navy bomb disposal world. Retiring in 2017, he became a Senior Department of Defense EOD expert, ensnared in PPTX, heroic administrative battles, and occasional paper cuts. If sitting is the new smoking, he was up to three packs a day.

Frankly, he is not too interested in talking about degrees, military awards, or material possessions. What he really wants to get at is results. CJ left the desk commando life to build an unconventional NGO offering a future filled with putting beans back in the jar. His favorite phrase is, “life is measured by what you give, not what you get.” Join us, and change your life.

After retiring from the U.S. Navy in 2020, Chuck embraced academia to broaden his horizons while concurrently working in the private sector as a senior consultant. Platinum East offers him the means of fulfilling his personal purpose of “being the pebble creating waves to change the world” in serving communities affected by the scourge of explosive remnants of war.

What we do

Our Approach

We built Platinum East upon the principles of innovation, creativity, and agility. Rather than leaving our tasks to a committee, we apply the best resources, people, and tools to get things done quickly, under budget, and in a way that promotes resilience, health, and security in the communities we serve.

We believe in keeping things simple and focusing on solving problems with those we serve. With our approach, we can help communities recover in a way that best meets their needs and creates a lasting impact. Our dream is to leave the world a better place than we found it, and we do that each and every day in countries around the globe.

Restoring Our Oceans

Two hundred countries around the globe have underwater ordnance polluting their streams, bays, rivers, and oceans. This hazard limits access to these resources, poses health risks, and denies the local community the ability to enjoy all that their environment has to offer. Platinum East has a team of experienced and highly trained underwater ordnance specialists who are able to remove these hazards and, in many cases, recycle the explosive waste. We accomplish your goals by leveraging our diverse network of experts and by working with your community to develop equitable measures to restore our oceans to their former natural splendor.

Renewing Our Communities

Explosive devices left behind after conflict present a persistent problem for many cities and villages around the world. These hazards can and frequently do kill innocent people seeking to return to their homes after prolonged periods of exile. Platinum East is able to mitigate these threats and provide critical information to safety officials seeking to restore order after the chaos of war. Everything we do is tied to building and supporting those we work with, and this collaborative approach allows us to provide long-term value to our fellow humans.

Join Us

Oceans cover more than 70% of the earth’s surface. People around the world are drawn to the water for recreation, adventure, and the pursuit of their dreams. For many people, it is also their source of income. After conflict ends, weapons of war are frequently left behind and what used to be a beautiful beach is now a hazardous environment. There is more ordnance polluting our world’s oceans than we will ever be able to clear by ourselves. If you have a passion for the environment and want to join us on our mission, click below and get involved. There is always more for volunteers to do, and we need people like you to help make our vision a reality. If you are not ready to get in the water with us, you can help by sending us a donation. All the support we receive supports our efforts to save lives and restore the world’s aquatic environment.

UXO Clearance

Underwater and surface ordnance present a hazard to your community, your people, your businesses, and your way of life. Here at Platinum East, we understand how complex site remediation can be, and we are deeply invested in our mission of saving lives by removing post-conflict remnants and restoring communities. Our team has more than 150 years of combined experience in this dangerous field. Whatever your problem is, we have seen it before. While we specialize in underwater ordnance, we are also able to handle ordnance of any type, including route clearance and  improvised explosive devices. In many cases, we can also exploit the items and provide technical reports to your local safety officials, enabling them to understand the threats they may see again in the future.


Saving lives is hard work, and Platinum East is only part of the solution. We believe the path to a better tomorrow is through education, and at Platinum East, we are committed to sustainable methods. To that end, we offer a variety of training modules to help the communities we serve. We do not burden those communities with expensive equipment with high maintenance costs, complex storage requirements, and priced-out consumables. Instead, we teach tried-and-true methods that EOD technicians have used for decades, combined with innovative, low-cost, scientifically supported techniques and tools to defeat yesterday’s explosives with today’s technology. We offer training on every service we provide. As part of our community restoration goal, we aim to train members of the local community to participate in our relief efforts. Our personnel are professional, seasoned, and exemplary leaders, mentors, trainers, and advocates. Together, we will prepare you and your community to take back your oceans, fields, and villages from the explosive hazards standing between you and your future.
