Many different types of situations could have run-offs of pesticides. Most of these are found on farms when they are sprayed to reduce the amounts of insects in the soil.
lakes/rivers/lakes/dams/drinking reservoirs/ Regarding actual types of runoff, pesticides would most likely be found in farm and agricultural runoff resulting from ploughed furrows between crops.
By runoff of rain water or irrigation water.
Agricultural runoff is a form of pollution when pesticides and other waste from a large area of land form into a small group and pollutes surrounding water.
Chemicals such as pesticides cause water pollution from storm runoff.
too big a question. what kind of details? which pesticides?
Runoff causes sheet erosion which means removing a thin sheet of topsoil.

Pesticides can enter waterways through runoff from agricultural fields, urban areas, and residential areas. Rainfall can wash pesticides off of crops, lawns, and roads, carrying them into streams, rivers, and ultimately into lakes and oceans. Improper disposal of pesticides and accidental spills can also lead to contamination of waterways.
Runoff can be harmful because it can pick up pollutants like pesticides, fertilizers, and oil as it flows over paved surfaces or bare soil. When this contaminated runoff reaches water bodies, it can harm aquatic ecosystems, degrade water quality, and pose risks to human health. Efforts to reduce runoff and promote sustainable stormwater management practices are important for protecting the environment.
A common pollutant found in road runoff is petroleum-based products such as oil, gasoline, and diesel. These pollutants can come from vehicle leaks, spills, and exhaust emissions, and can contaminate water sources if not properly managed.
An example of agricultural runoff is the excess fertilizer and pesticides that wash off fields during rainstorms or irrigation. This runoff can carry harmful nutrients like nitrogen and phosphorus into nearby rivers and lakes, leading to issues such as algal blooms and water pollution. These blooms can deplete oxygen in the water, harming aquatic life and disrupting ecosystems.
Agricultural runoff containing fertilizers and pesticides is a common example of a nonpoint source of freshwater pollution. When it rains, the chemicals from the fields can be washed into nearby streams and rivers, contributing to water pollution.
