Members of the USC Foundation receive a subscription to Cross Talk, a quarterly newsletter, which informs members of the latest news concerning backflow and cross-connection control. Cross Talk becomes an invaluable source of information and is a primary tool that the USC Foundation uses to communicate to its members directly. Become a member of the USC Foundation.
USC Foundation members are mailed the latest copy of Cross Talk every quarter. For everyone else, Cross Talk's published more than a year ago are available for download.
Below you will find an archive of Cross Talk's dating back to 1967. All copies are available in Adobe PDF format. Get Adobe PDF Viewer.
The issue offers an inside look at the Foundation's Approval Process of backflow preventers along with articles about One Day Update Seminars, 25 Year Members and Gage Squirting.
