North Korea’s Nuclear Weapons: Technical Issues
“This report summarizes what is known from open sources about the North Korean nuclear weapons program—including weapons-usable fissile material and warhead estimates—and assesses current developments in achieving denuclearization. Little detailed open-source information is available about the DPRK’s nuclear weapons production capabilities, warhead sophistication, the scope and success of its uranium enrichment program, or extent of its proliferation activities.”

Oilfield Contamination of Water

Missoulian: Feds: EPA fails to protect water from oilfield contamination

EPA Needs to Collect Information and Consistently Conduct Activities to Protect Underground Sources of Drinking Water

”Since the early 2000s, increased oil and gas production has resulted in an increase in wastewater that must be managed properly. The majority of wastewater from oil and gas production is injected into underground wells known as class II wells. These wells are regulated to protect drinking water sources under EPA's UIC class II well program and approved state class II programs. EPA oversees state programs, and EPA regions manage programs in states without approval.”

Prairie Dog Conservation
“Black-tailed and white-tailed prairie dogs are native to Montana. The black-tailed prairie dog was abundant and widely distributed throughout grassland and shrub/grassland habitats east of the Continental Divide during the 1800s. The historic range of the white-tailed prairie dog was restricted to shrub/grassland habitats of the valleys located between the Beartooth and Pryor Mountain ranges in south central Montana. Both species declined in abundance during the 20th century.”
