The major causes of groundwater pollution in the united states are fertilizers, pesticides, and chemical spills. true false

the answer is TRUE

I think that'd be correct. I'm not 100% sure, though. Pesticides in water is actually very bad and can kill plants, animals and humans alike. It's a common thing that you can hear about. Chemical spills are clearly going to be bad for the environment. Fertilizers I'm not too sure about though, as well as it being the major cause of groundwater pollution in the US. But hopefully someone else can give their thoughts as well.

Passive transport is the answer
