Cow Island is an unincorporated community in Vermilion Parish, Louisiana, United States. [1]
Cow Island was the subject of controversy over suspected arsenic releases from cattle dip tanks; residents of the city sued a pharmaceutical company for US$5 million in cleanup costs for arsenic-contaminated water, but a later study suggested the arsenic may have been geologic in origin. [2]
