Regarding the verb “judge”, I wonder whether I can reduce “to be” in these sentences without affecting the meaning

1.The water was judged to be of good quality.

2.The water was judged (to be) of good quality. ?The water was judged of good quality.

3.The scientists judged the water to be of good quality.

4.The scientists judged the water (to be) of good quality. ?The scientists judged the water of good quality.

I wonder whether we can regard "to be" as implied without affecting the meanings of 1 and 3, in sentence 2 and 4 between "judged and of" and "the water and of".
