My LINQ Query below works fine

However...

There are about 500 empty or zero length records being inserted into the results set.

How do I exclude those records in the select?

            Dim Query = _
            (From Region In dataset1.Tables(0) _
             Select Region.Field(Of String)("Region")).Distinct().OrderBy(Function(item) item).ToList

Try it like this.

Dim Query = _
    (From Region In dataset1.Tables(0) _
     Where Region IsNot Nothing _
     Select Region.Field(Of String)("Region")).Distinct().OrderBy(Function(item) item).ToList

Put me on the right track.

The final solution was actually this one...
There WAS data there...but it was = ""
Dim Query = _
            (From Region In dataset1.Tables(0) _
             Where Region.Field(Of String)("Region") <> "" _
                    Select Region.Field(Of String)("Region") _
             ).Distinct().OrderBy(Function(item) item).ToList
