Sort of.. As it happens, the lossiness of water is very frequency dependent.
At typical TC frequencies, 100 kHz to 1 MHz, water is a lot less lossy than
at 2450 MHz (microwave oven frequency).  At low frequencies, the loss
mechanism is likely to be just from conductivity, and for highly distilled
water, it would be quite low.
