The most popular water system is Brita. You can buy filters that attach you your faucet, or ones that come in a freestanding pitcher, which is filled up from the tap.
it is run off of a different line from the main water supply. you may be able to trace it from the hot water tank and see where it branches off.

Yes, it can also cross through a two handled faucet. Both the hot and cold sides of the faucet must be on and the flow of water must be stopped or greatly reduced on the outlet side of the faucet. This can occur when a hose with a spray nozzle is attached to a laundry tub faucet with the faucet on and the spray nozzle off, or when a shower faucet is on but the shower spray head is off. When another cold water outlet in the system is turned on then the pressure on the cold side of the laundry tub or shower faucet in question could be lowered below the pressure on the hot side and hot water can flow into the cold water side. There are faucets which have integral check valves which prevent this from occurring. WWW.WOODBRIDGEPLUMBING.COM

The faucet itself does not use any water. The rate at which the water leaves the faucet is dependent on the make of the faucet.
Water is coming down from upstairs or it is back pressure from the water heater. If it is the water heater, it can come out of either side of the faucet.
Unless there is a recirculating pump the hot water has to come from the hot water heater. Depending on how far away it is from the faucet, it can take 15 to 30 seconds for the hot water to get there. Since there is nothing in the pipe to keep the water hot, it cools down between uses.
Yes, some faucet water has bugs in it.
Do all the faucets do this or just one. if its just one faucet its a problem with this fauset. If its all the faucets in the home its a problem with the main water line coming into your home.
