stagnant water
Motionless breeding pool
Stagnant water is water that doesn't flow or circulate—standing still in ponds, puddles, or neglected containers.
Without movement, it becomes depleted of oxygen and hospitable to mosquito larvae, algae, and harmful bacteria: Stagnant water collected in the old tires behind the shed.
The phrase often implies something unhealthy or neglected.
