4-nonylphenol (4NP), a breakdown product of nonylphenol polyethoxylate, is a potent endocrine disruptor and persistent organic pollutant (POP). Due to physical and chemical properties, 4NP is capable of long range transport as both an aerosol and attached to dust particulates. Since nonylphenol polyethoxylates make up a substantial portion of many pesticides, agricultural regions are often sources of 4NP. Physical barriers such as mountain ranges may alter the distribution of this POP but does not stop the long range transport. The Central Valley of California, USA is an intensely farmed region adjacent to the Sierra Nevada Mountains subjected to onshore prevailing winds from the Pacific Ocean. Previous work revealed that the winter snow pack in the Sierra Nevada showed at least an order of magnitude more 4NP than surface water during summer months. As a result, spring melt water may ..
