Contaminants surveillance data in freshwater at sites in the Pacific Basin are included in this dataset. Measurements may include physical-chemical parameters such as temperature, pH, alkalinity, and major ions; nutrients, metals, pharmaceuticals and personal care products, pesticides and persistent organic pollutants. The number of sites varies from year-to-year, and sampling frequencies vary from one location to another, as surveillance activities are adjusted according to evolving environmental pressures and governmental programs. Data are collected in order to determine baseline water quality status, evaluate the effectiveness of management actions, verify compliance with water quality objectives, and identify emerging issues.
