Lined ditches reduce the delivery of sediment-attached nutrients to surface water.

Lining eliminates seepage.

The action eliminates the potential for irrigation water to pick up salts from the ditch.

The action eliminates seepage from earth canals which can move soluble salts to the ground water. 

May collect runoff and return flows that could deliver contaminates to surface water.

The action eliminates seepage losses from canals, which reduces the potential for movement of pathogens to groundwater.

The action eliminates seepage losses from canals, which reduces the potential for movement of heavy metals to groundwater. 

Impervious materials prevents erosion.

Conservation irrigation systems minimize affects to surface water quality.

The action may collect runoff and return flows may deliver possible contaminates to surface water.
