The Clean Water Act has made great strides in reducing point source water pollution, but this effect is overshadowed by the fact that nonpoint source pollution, which is not subject to regulation under the Act, has correspondingly increased. [41] One of the solutions to address this imbalance is point/nonpoint source trading of pollutants.
Water metering might benefit society by providing a financial incentive to avoid waste in water use.

Map of global water stress (a symptom of water scarcity) in 2019. Water stress is the ratio of water use relative to water availability and is therefore a demand-driven scarcity. [45] Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of ...
The most widespread strategy is "reduction at the source", which is the idea that byproducts of production can be reduced through efficient and careful use of natural resources. This method reduces the amount of dangerous pollutants present in waste before the waste is released. In turn, this creates a safer environment free of hazardous waste.
