Zarjoob

Zarjoob or Zarjoub, in Gilan province, northern Iran, is a 41 km river that passes through the city of Rasht and empties into the Anzali Lagoon near the city of Bandar-e Anzali on the Caspian Sea.

Pollution
Despite its short length, the Zarjoob watershed is home to about 1 million people and the river is heavily polluted. Sources of pollution include leaching from a landfill that receives some 700 tons of waste per day, approximately 500 factories, domestic and hospital wastewater, and agricultural runoff from rice paddies.
