Every state has a state University that has an extension office that deals specifically with this area. They send you test bottles and a mail back kit. When they send you the results, it will state on there, what you need to do to correct the problem. The state Health departments also handle the testing and can shut a well down, if the contamination levels are far higher than what can be removed, if at all.
Any Arsenic in ground water, is not good for the body. You are talking about a very expensive system with a lot of upkeep, to make sure that the levels are kept below the levels that can cause cancer or even death. Average cost can run around $1500, just for the Reverse Osmosis system.
"In the United States small "under the sink" units have been used to remove arsenic from drinking water. This option is called "point of use" treatment. The most common types of domestic treatment use the technologies of adsorption (using media such as Bayoxide E33, GFH, or titanium dioxide) or reverse osmosis. Ion exchange and activated alumina have been considered but not commonly used.
Chaff-based filters have been reported to reduce the arsenic content of water to 3 microgram/litre. This is especially important in areas where the potable water is provided by filtering the water extracted from the underground aquifer."
This Ohio's memo on proper treatment and removal. All of the states are pretty much along the same guidelines. https://www.odh.ohio.gov/~/media/ODH/ASSETS/Files/eh/water/factsheet/As_treatment-removal.pdf
