Water Chemistry

Water chemistry deals with all properties of the water and all the substances in the water. In an estuary like Narragansett Bay, the water and the substances in the water are always changing. The changes of the water are due to of the influence of both fresh water from the land and salt water from the ocean. Scientists monitor water chemistry in Narragansett Bay to determine the health of the bay. These are some of the water properties measured in Narragansett Bay.
