- Black smoke being released from a large truck doesn't affect water at all, the only thing it affects is the air. Which is air pollution.

- Oil refinery's dump waste into bodies of water. Refinery's tend have pipes connecting to bodies of water so, when toxic waste is disposed it's normally taken to ponds/lakes/rivers/oceans.

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )
