If the water table was really that high, when the building was rebuilt, how did they not diaphragm the field area to keep the water out? You can place building foundations in a high water table by using "piles", not as in mounds but as in columns that extend down into the muck a la Venice Italy. But how did they not protect the field? They had to of, and if the result was a very shallow soil layer or the inability to grow grass at all, then the very use of grass was a total compromise and [expletive].
