No, they are not legally required to give you the report. It is their report--they paid for it, and it belongs to them. The law does not make landlords share environmental or testing reports with tenants. You have two options:1) Pay to have the water tested yourself--if you don't want to bring the testing company to your apartment, take samples to the tester. If the water is unsafe, you would then likely have grounds for a lawsuit, and could look to recover the testing cost as well as other compensation.2) Sue the landlord if you are convinced the water is bad for your girlfriend's health. You could seek recovery of her medical costs, compenation for her worsened condition, etc. In the course of a lawsuit, there are legal mechanisms (e.g. a notice to produce documents; written interrogatories or questions) to get this report. Of course, you will not actually know if the suit--and its cost and effort--is warranted when you first file it, unless you do as per 1) above and get the water tested yourself.
