A couple of things from the top of my head:
(1) Pool owner added to much sodium bicarbonate, error in calculating quantity to use or wrong pool volume (been there, done that);
(2) Using well water: high in CO2 content from decaying organic matter. This high CO2 content increases the bicarbonate content:
CaCO3 + CO2 + H2O -> Ca+2 + 2HCO3-
(3) Using sodium bisulfate as a method to increase pH, this also increases TA;
(4) Failing to adjust TA figure to take into account a high CYA (CYA is another buffer system and when high enough it may influence the TA test);
If I think of anything else I'll post back.
