CANNON BALL, N.D. - After a quiet weekend near Cannon Ball, a group of Dakota Access Pipeline protesters illegally made their way to construction grounds, sending workers away from the site.
Protesters against construction of the Dakota Access Pipeline picked up their demonstration efforts Monday morning. They say any leaks in the oil pipeline could threaten their water supply, and that's not a risk they're willing to live with.
And with more people joining their demonstration, law enforcement says it's uncertain what could happen in the coming days.
"From identifying people, then we will see where this goes, down the long road. You know this is going to be a while," says Morton County Sheriff Kyle Kirchmeier.
It's uncertain what will happen to the group, but Sheriff Kirchmeier says there were 10 arrests made Monday. He says demonstrations need to be re-evaluated and that the officers are there to help.
"We're here to make sure that this goes good. We can see what we can do to help it out on their end also," says Kirchmeier.
He says one way is possibly expanding the protest space, and with the number of protesters growing, it may be needed. Native Americans from across the country are traveling to the site to show their support.
"Things are happening, and it's a gathering of nations - great nations - and it fills me with pride that we can all come together as one once again," says Terry Phillips, protester.
Protesters have stayed by the site since the Army Corps of Engineers granted permits for construction. They fear what the project could do to the water quality on the Standing Rock Sioux Reservation, and beyond.
"There's no boundaries when it comes to water. You need it, I need it, every living creature needs it," says Phyllis Young, protester.
Protesters say the numbers will continue to grow, with more coming everyday.
Developers of the project have filed a federal lawsuit to stop protesters from taking actions on the construction site.
