Is it true that rapid snow melting in the spring can cause a sudden increase in the acidity of streams and lakes?
Yes. Rapid snow melting in the spring routinely triggers episodic acidification, lowering the pH of vulnerable streams and lakes through increased runoff of acidic compounds.

Evidence for · 3
Demonstrates that spring snowmelt runoff results in a major decrease in pH (acidification) and a sharp increase in hydrogen ion content in central Ontario streams and lakes.
