North Dakota wind can send more than leaves tumbling down the street. 💨 Secure trash and recycling, pick up loose litter and keep storm drains clear. What blows away can eventually make its way into rivers, lakes and streams.

We love seeing young scientists in action! 🔬💧

NDDEQ Environmental Scientist Meridith Miller recently joined Mott-Regent High School biology students for hands-on water quality sampling training through the Cannonball River Citizen Science Initiative. Students learned sampling techniques, safety protocols and field procedures while exploring how science helps us understand and protect local waters.

Thank you to the students, educators and Hettinger County Soil Conservation District for supporting this valuable experience!

We’re excited to congratulate John Lee and Ellen Njos of Coyote Creek Ranch on receiving the 2026 North Dakota Leopold Conservation Award.

The Njos family has spent decades showing that good ranching and conservation go hand in hand. Their willingness to try new ideas and share what works has made a real difference on their land and across North Dakota.

Watch below and join us in congratulating them!

September is National Preparedness Month. This year’s theme, “Americans Stand Ready,” reminds us that taking a few simple steps now can help protect our families, communities and environment when the unexpected happens.

Environmental preparedness can include:

✅ Checking North Dakota’s Air Quality Index, especially during wildfire smoke: https://deq.nd.gov/aq/monitoring/
✅ Knowing your local risks and preparing for emergencies such as floods and severe weather
✅ Storing fuels, oils and household chemicals safely
✅ Knowing how to report an environmental spill

All spills in North Dakota can be reported online at https://spill.nd.gov. Incidents requiring immediate reporting should also be reported by calling 1-833-99SPILL. Call 911 for an immediate emergency.

$11.7 million in water infrastructure loans awarded! 💧

The State Revolving Fund programs awarded six loans to four North Dakota communities in August to support critical water infrastructure improvements.

Projects in Casselton, Stanley, Bowman and Grand Forks will help improve water and wastewater systems, increase reliability and reduce operation and maintenance costs.

These investments help communities maintain the infrastructure that keeps clean, reliable water flowing across North Dakota.
