Non-point source pollution refers to diffuse contamination that does not originate from a single, identifiable source, making it challenging to regulate and manage. It often results from runoff carrying pollutants from agricultural fields, urban areas, and other widespread sources into water bodies, impacting ecosystems and human health.

Agricultural runoff refers to the water from rain or irrigation that flows over farmland, picking up pollutants like fertilizers, pesticides, and sediments, and carrying them into nearby water bodies. This process can lead to nutrient pollution, harmful algal blooms, and degradation of aquatic ecosystems, posing significant environmental and public health challenges.

Agricultural Runoff

Urban runoff refers to the surface water flow that occurs in urban areas due to rainfall or snowmelt, which is unable to infiltrate the ground because of impervious surfaces like roads and buildings. This runoff often carries pollutants into natural water bodies, leading to environmental degradation and water quality issues.

Urban Runoff

Pollutants are substances introduced into the environment that cause harm or discomfort to ecosystems or living organisms. They can be natural or anthropogenic, and their impact depends on their concentration, persistence, and the sensitivity of the affected environment.

Ecosystems are complex networks of living organisms and their physical environment, interacting as a system through nutrient cycles and energy flows. They can vary greatly in size and complexity, from a small pond to an entire forest, and are crucial for maintaining biodiversity and ecological balance.

Human health is a multifaceted state of physical, mental, and social well-being, not merely the absence of disease or infirmity. It is influenced by a complex interplay of genetic, environmental, lifestyle, and healthcare factors that can affect an individual's ability to lead a fulfilling life.
