Why was this change necessary? (If left off the plans and specifications, explain why)
ConstructiqJl well drilled on site and three nearby wells exceeded TCEQ limits for Chlorides and Total Dissolve
Solids for ~ublic potable water supoly. Levels were such that reverse osmosis was unlikelv to be cost effective
and miqht not oroduce water meetinq TCEQ standards.
How can similar changes be avoided in the future? Would require drillinq a well in advance of construction.
