While not all wells can become contaminated, it is important to know why some become contaminated (leached) and why others do not.. By their nature, pesticides are potentially toxic to other organisms, including humans, and need to be used safely and disposed of properly. In a landmark ruling in August last year, Monsanto was found liable for causing a school groundskeepers cancer through exposure to Roundup, the companys leading pesticide. Chemical pest control has contributed to dramatic increases in yields for most major fruit and vegetable crops. The slow movement of groundwater means that it may take decades for the contaminated water to flow beyond the affected wells. Most environmental toxins are an unwanted by-product of another process (for example, out ow from a manufacturing plant or emis-sions from an automobile engine). Humans, animals, aquatic organisms, and plants can be severely threatened by these chemicals.
