As for the duplicate key I would first check to see if you are inserting

conflicts with existing records on the waterchem table.  The easiest way
would be to insert into a staging table and then join the staging and live
tables together on the PK and see if any records are returned.

David,

  Since the two separate tables have no duplicates I find it difficult to
understand how combining the two generates a duplicate row.

  In any case, I always drop the table before running the script after
correcting errors so there should not be a previous row with the same
values. Puzzling,

Thanks,

Rich
