Over two-thirds of the plant (planet I assume?) is covered by it, and humans will die within 3 to 7 days without it. Water is the most precious resource on the planet, but can also be taken for granted especially in first-world countries where it is always available at the faucet. This modern marvel of having clean water so easily accessible is threatened by another modern invention, the application of pesticides. While pesticides have narrowed the gap between actual yield and yield potential in our conventional crops, they are also a source of nontarget poisoning responsible for fish kills, reproductive failures in birds, and human illnesses (Arias-Estevez et al, 2007). In fact, only about 0.1% of pesticides actually reach their targeted pest (Pimentel, 1995). Most pesticide ends up in the environment where it is transported or degraded through volatilization, runoff into surface water and groundwater, or taken up by nontarget organisms (van der Werf, 1996). The movement of pesticides into groundwater poses a grave threat to the health of our communities. According to a 1999 USGS survey, around 50% of water samples collected from wells contained at least one pesticide (Arias-Estevez et al, 2007). In Ohio, a well testing program started by the Water Quality Laboratory of Heidelberg College found that wells were contaminated most frequently by atrazine and alachlor, albeit at very low levels and in less than 5% of wells (Baker, 1990). There is a need to identify pesticide
