This bill would require the Department of Environmental Protection (DEP), in consultation with the Department of Parks and Recreation and the Department of Health and Mental Hygiene, to conduct testing of the bodies of water abutting New York City recreational waterfronts at least one time per week in July and August of each year, and one time per month in all other months, concerning levels of harmful substances, including but not limited to harmful algal blooms and petroleum. This bill would also require DEP to post on its website the results of its testing within three days after each instance of testing.
