The attached report, "Interim Performance Report on Morton's Gap Culvert Pipe Installation", by James H. Havens, is primarily a listing of the status of the condition of pipe still in the test and the date of failure or removal of the other sections.

Mr. Havens has prepared as background information, a brief record of the Department's practices involving pipe use for the past 10 years. He has begun with the Research Division's first study into pipe damaged by the corrosive action of acid water. This information is presented primarily because of its significance in the development of the culvert pipe test installation.
