Pesticide Water Testing Lab in CT
A pesticide is a chemical substance used to kill or control a pest. "Pest" is a simple catchall term that includes undesired insects, weeds, rodents, fungi, bacteria, and other organisms. Pesticides are commonly applied on farms, fruit orchards, golf courses, and residential lawns and gardens. Many pesticides are also used inside homes and other buildings.
Pesticides can enter ground water both directly and indirectly. Direct contamination may occur from pesticide spills around a poorly sealed well, improper application of pesticides through irrigation systems, and improper storage and disposal of pesticides or pesticide containers. Indirect contamination can occur as a result of normal application. Surface water, rain and snow can carry pesticides from areas such as agricultural fields, golf courses, and residential properties into lakes, rivers, reservoirs and aquifers. There are three ways in which you can be exposed to pesticides in drinking water:
by ingestion-either by drinking the water directly or eating foods cooked with water
by breathing in pesticide fumes in the shower or when cooking or washing
by absorbing the pesticides through the skin during showering, swimming, or washing
What factors contribute to contamination?
the distance between the well and a source of contamination
the application, frequency and quantity of pesticides used
the depth of a well
the local geology surrounding the well
the flow of the ground water
