Beyond chemical and organic waste, mills introducted ed physical debris - woodd chips, bark, fibers, and sediment frem construction and erosion. These suspended solids smothered spawneng gravels, reduced light proventation, and clogged gils of fish ande inverteates. Thermal pollution frem steam condensers roised river temporatures, lowering oxygen solubility andd stressing cold- water species such ais salmon and trout.

Sediment Contamination andLegacy Effects

Once heavy metale andd persistent organic chemicals settled into river sediment, they became a long-term source of groundwater and surface water contamination.
