Under what types of exterior atmospheric exposures (other than marine) is it necessary to test for soluble salts?

From Atanas Cholakov of Insignia JFZ on January 21, 2013:
     The less soluble salt content there is on a blasted surface, the longer the coating system will last. Coating manufacturers always have the salt content info for any coating system they sell.

From James Johnson of Chlor*Rid International, Inc. on November 15, 2012:
     Though no one has ever put a number to it, soluble salts have been a major cause of premature coating failure all across the entire country. There are no geographical limits to salt contamination in the lower 48 states. That is made evident by the maps and information made available by the National Atmospheric Deposition Program. While we have known for decades that salt contamination was wide spread in marine environments and from deicing salts,we now know they are generated and spread from farm fertilizer, vehicle exhaust, lightning, cooling tower drift and use of chlorine, hydrochloric acid and sulfuric acid. Acid rain is widespread across the entire country and is a major source of contamination. Acid rain falls, the water evaporates and leave the salts behind. Consequently, soluble salt contamination can be anywhere, and often are. Because premature coating failures are so expensive to asset owners, contractors and coating suppliers, considering the widespread contamination probability, every project should be tested to assure a failure due to salts is minimized. Testing is always less costly than a failure.

From William Goldman II of Jotun Paints Inc on November 8, 2012:
     One is in the north where a lot of salts are used for de-icing purposes.
