Does anyone know how long it would take for someone to die if they injested arsenic-contaminated water? I know that arsenic can be found in groundwater naturally, but when I googled I kept getting things like "long-term exposure" without any clear definition of what "long-term exposure" is. Weeks? Months? Years? Also, how long it would take for someone to start showing symptoms? In my story the arsenic-contaminated water is the only water source available and would be used for everything - drinking, cooking, etc.
Any help is appreciated. :)
