Community groups say Louisiana is trying to stop them from monitoring air pollution

2. Bucket brigade

This movement for citizen air monitoring began many years ago. Neighbors of noxious facilities were taught how to build buckets that could take air samples. The collected samples would then be analyzed at a laboratory. The monitoring was a way to involve the community, to demystify the air monitoring process, and to pressure air regulatory agencies. But, as I recall, the lab analysis cost money and, typically, regulators would continue their see-no-evil stance.
