Iron is much to high. Not sure about the smell. What does it smell like? Rotten eggs, rotting plants, rotting fish? I would recommend a real water test considering the chep cost to have it done properly. A full test will cost you less that few hundred dollars.
At minimum, an iron removal system should be installed followed by a softener if you desire.
There are dozens of ways to do this. Each with its pluses and minuses.
With the minimal information provided, a simple chlorine injection, contact tank, and backwashing carbon tank would be a good place to start. Followed by a softener if you want softened water to remove the scale that you are likely to get with your water.
Chlorine injection can be done in many ways, I perfer a Chemilizer or similar injection pump, but be warned, they can be noisy. Followed by a simple contact tank with a manual blowdown and a backwashing GAC tank. other treatment methods use aeration, oxidation, etc but each one has its problems and should be done by a local professional who understands your water supply. The method I described may not be the most efficient but is is reliable, simple, and relatively cheap. Other methods include chlorine tablet feeders. these are ok, some people swear by them, others swear at them.
