OOOH! We just did this in AP Enviro! (I have a test tomorrow in this unit...) Pesticides kill insects and they all have the potential to pollute water. Like Kevin W. said, if you meant CANNOT pollute water, science has not really invented that yet. There are, I'm sure, microbial agents that cannot live in water, or at least do not pollute it, that kill insects in various stages of their lives. But I don't know of an insecticide that doesn't have the potential to pollute water unless the reason would be low toxicity to aquatic life and persistence of only a few hours or days, in which case I'd research natural organic pesticides.

If you are thinking "Cannot" pollute water, I'd try for an insecticidal soap. The ingredient in these that kills insects is potassium salts from fatty acids. Since it is safe enough to eat the sprayed plant 24 hours later, I would say that this is non-harmful to water sources. Another good one is "tobacco tea"...simply make a tea out of cigarettes or other form of tobacco. This also degrades quickly, unlike many of the insecticides created from fossil fuels.
Baits and traps that target specific insects are also better for water sources, since they tend not to travel beyond the area where they are placed.

Er... methane base pesticide.
If you mean to say CANNOT pollute water, well, just wait a few more years till technology solves that problem

Are you referring to DDT?
