===Liquids===
Water quality will be similarly graded as A, B and C.  Usually we will be dealing with a water source.  A Water is clean and fresh like from a mountain stream or a Coca Cola bottling plant (ie Aquafina) and grants a +1 to morale.  B Water is potable but probably has some brownish tinge to it – no morale modifier.  C Water is susceptible to disease and common in urban areas, runoff, etc. and causes a -1 morale penalty.  For variety, a +1 will be provided if individuals have access to one non-alcoholic liquid (such as tea, juice, etc.) and a further +1 if they have access to alcoholic liquid (wine, beer, spirits, etc.).

You need a half gallon per day when traveling (hopefully characters will have access to unlimited water at fixed sites), which is 4 pounds.  Liquid types are consumed in the same manner as food but 2 times as much water as other liquids.
