Nonpoint Source pollution also comes from agriculture. American agriculture is known worldwide for high productivity, quality, and efficiency in delivering goods to consumers. When they are improperly managed, however, agricultural activities can affect water quality. There are many agricultural activities that cause nonpoint source pollution. They include pesticide spraying, irrigation, fertilizing, planting, and harvesting.
Agricultural activities can damage habitat and stream channels.
Its impact on surface water and ground water can be reduced by properly managing activities that can cause nonpoint pollution. 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.
