Abstract
This document integrates, or synthesizes, the results of 40 technical studies of the Chesapeake Bay's resources and water quality in three problem areas: nutrient enrichment, toxic chemicals and declining submerged aquatic vegetation. Nutrient enrichment in the Bay was evaluated by measuring a number of related factors including nutrient concentration and oxygen levels in the water, amounts of chlorophyll a, and transparency of the water. Historical records of these measurements were gathered and analyzed to look at trends in nutrients over the past 20 years. Toxic substance research focused on determining the status of both metals and organic compounds in the Bay, including their concentration in the water column, bed sediments, suspended sediments, and in some bivalves. Submerged aquatic vegetation (SAV) has, in the past, been very abundant throughout the Bay. Current evidence indicates a pattern of SAV decline that includes all species in all sections of the Bay.
