Pesticides are man-made substances used to control unwanted pests or vegetation. Pesticides are usually made up of a combination of active and inert chemicals and materials that can break down in the environment into substances often more toxic than the original materials. Examples of pesticides include insecticides, herbicides, fungicides, defoliants and desiccants. […]

Pesticides get into stormwater by being dissolved or attached to soil particles and carried away in runoff. Pesticides can also enter the groundwater if the pesticide is highly water soluble and applied before a large rainfall event or regular irrigation. A form commonly found in stormwater is 2,4- Dichlorophenoxyacetic acid (2,4-D); glyphosate (Roundup). [ii] DDT […]
Pesticides should be removed from stormwater discharge because their presence in water sources can have serious, adverse effects on human health and the viability of fish and wildlife. Certain pesticides can irritate human tissue, damage the nervous, immune and endocrine (hormone) systems, increase the risk of cancer and even cause death.[iii]
Pesticides most frequently found […]
Enhanced, passive media filtration and advanced polishing can be used to effectively remove pesticides from stormwater prior to discharge. If further reduction is necessary to remove pesticides, advanced polishing technologies can be used. Both types of BMPs combined in a treatment train will remove pesticides from stormwater prior to discharge to help facilities meet benchmarks […]
Turbidity should be removed from stormwater because its presence in drinking water sources has negative effects on humans and the environment.
The effects of high turbidity levels in water ingested by humans often mean higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria, which can cause symptoms such as nausea, cramps, diarrhea, and […]
TSS should be removed from stormwater because the effects of high TSS levels in water ingested by humans often mean higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria, which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.[i]
TSS can also make water bodies in the environment less aesthetically […]
