Eureka - Carbon Dioxide (CO2) Sensor - Brochure

Carbon dioxide can enter the water through multiple pathways. Some primary land sources can include decay of organic matter, dissolution of carbonate rocks, wastewater discharge, and watershed draining. Other natural sources include biological respiration, sediment diagenesis, or volcanic activity. A major source/sink of CO2 is atmospheric exchange at the air/water interface. Simply, carbon dioxide gas dissolves in water.
