The below sentence was given as an example in chapter 12, of the SC GMAT Strategy Guide.

"At current prices, oil in antarctic may be worth drilling for, if wells can be dug there and environmental concern addressed."

Unable to understand how parallelism is brought by using AND, because environmental is a adjective and wells is a noun.

At current prices, oil in Antarctica may be worth drilling for, if:

(1) wells can be dug there = noun (wells) + verb (can be dug)

and

(2) environmental concerns addressed = modified noun (environmental concerns) + verb (addressed).

The parallelism is between phrases with similar, but not identical, structure. Concerns has an adjective preceding it, while wells does not--and that's OK.

What is the thought on ending the phrase with a preposition? I thought it was generally incorrect to end a phrase with a preposition. The word "for" seems out of place.

you have a point. this sentence would probably be better rendered as
it may be worthwhile to drill for oil in the antarctic

(note that this is the special case of "it is ADJ that/for/to..." --> the one and only instance in which it's ok for the pronoun "it" not to refer to anything)
