iRRigating efficiently: wateRshed management stRategies

concern of over irrigation is increasing agrochemical concentrations in the groundwater, which
may impact humans if the groundwater is a source of drinking water supply.

When designing irrigation systems, it is critical to consider watershed implications. If wa-

tershed level implications are not considered, downstream waters may be altered in a way

that prevents their designated uses. Restoration of such damage to waters is almost never

attainable although rehabilitation may occur with appropriate management.
