The Environmental Protection Agency (EPA) defines pesticides as any chemical substance used to regulate, prevent or destroy plants or pests usually insects, rodents or microorganisms such as fungi and bacteria or that acts as a nitrogen stabilizer in soil. Center for Integrated Pest Management. 2. Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. If, however, the pesticide degrades quickly or is tightly bound to soil particles, then it is more likely to be retained in the upper soil layers until it is degraded to nontoxic by-products. Private Drinking Water Wells. Even though pesticides are sprayed on land, many times, they can make their way into a water source, such as a river, ocean, or pond. active ingredient(s) in the pesticide formulation, contaminants that exist as impurities in the active ingredient(s), additives that are mixed with the active ingredient(s) (wetting agents, diluents or solvents, extenders, adhesives, buffers, preservatives, and emulsifiers), degradate that is formed during chemical, microbial, or photochemical degradation of the active ingredient.

This is of particular concern in areas where frequent irrigation is necessary because of coarse-textured soils. Table 1. Toxins in Water and Food. There are many ways in which pesticide contamination can be prevented such as selecting the appropriate pesticides, proper pesticide mixing, and loading procedures. Pesticides can enter the body through inhalation, through the skin from contaminated soil or water, or through contaminated food. Operation Water Drop looks at the chemical contaminants that are found in water; it is designed for a science class. (2017, Aug. 31). Leaching of pesticides depends in part on the amount applied per acre per year; where, when and how it is applied; the solubility of the compound: how strongly it is held by the soil; and how quickly it breaks down in the root zone. The Government of Canadas website states, Pesticides are stringently regulated in Canada to ensure they pose minimal risk to human health and the environment.
