Water Sentinels

The Long Island Water Sentinels work in partnership with the sSelf program* to gather baseline data of the local water quality. Water quality data is essential to understanding the problems that face our waterways.


The goal of the Long Island Water Sentinels program is to compile baseline water quality data for both the North and South Shores of Long Island. Long Island Water Sentinels train and equip adult, teacher, and student volunteers to do water testing in the field.* All volunteers work in teams, ensuring reliable and accurate data. Data is added to a spreadsheet that is available online.


Contact Nancy D'Angelo at with questions or to volunteer.
