The River Alt is an urban river that flows across Merseyside in England. The river has suffered from heavy pollution from industry and sewage upstream and run-off from farmland in its lower reaches. It empties into the River Mersey, near to where the Mersey itself flows into the Irish Sea. The river has benefited from clean-up schemes and a de-culverting process to improve its water quality and provide a better environment for wildlife.
