Malmstrom AFB, a key nuclear missile facility, has documented significant soil and groundwater contamination from firefighting foam use, with contamination plumes extending toward the Missouri River system and threatening Great Falls' water supply. The base's strategic importance and decades of operations have created extensive contamination requiring comprehensive remediation.
Montana's mining and energy industries have contributed additional PFAS sources through industrial processes and waste management practices. The Yellowstone River watershed, critical for agriculture and municipal water supplies, requires protection from expanding contamination sources. The state's vast agricultural economy faces particular challenges from contaminated groundwater affecting livestock operations and irrigation systems across the High Plains region.
Key Facts
