Herbicides in water refers to the presence of various chemicals used to control or kill off unwanted plantation or weeds that have found their way into the water source. Similar to pesticides, herbicides can enter water bodies through runoff from farmlands, golf courses, lawns and gardens, roofing, gutters and downpipes, as well as from industrial activities and accidental spills. Exposure to these chemicals through drinking water can have harmful effects on human health and wellbeing, including cancer, reproductive problems and developmental delays in children. Herbicides can also harm aquatic life, including fish, birds and amphibians, and have negative effects on ecosystems. It is important to regularly test and treat water to remove or reduce herbicide contamination, filtration systems, as well as to use alternative weed control methods that minimize the use of harmful chemicals.
