There is also another solution to nonpoint source pollution. When properly managed, wetlands can help prevent nonpoint source pollution from degrading water quality. Wetlands include swamps, marshes, fens, and bogs. Wetlands can intercept runoff and store pollutants like sediments, nutrients, and heavy metals without being degraded. Wetland vegetation can keep stream channels intact by slowing runoff and evenly distributing the energy in runoff.
Wetlands regulate stream temperature by providing streamside shading.
But in order for our wetlands to help with the problem, we first need to preserve our wetlands by limiting development. This law will state that construction and agricultural sites will be surveyed by at least five safety inspectors three times a year. The use of pesticides will be banned, but replaced with IPM, or Integrated Pest Management techniques, which will be based on the soil, climate, pest history, and crop for a particular field. These techniques should be determined by safety inspectors, based on the conditions. This helps limit pesticide use and manages necessary applications to minimize pesticide movement from the field.
