About the Cover
Cover: Pictured is a section of the interacting channels and adjacent carbon-rich peat soils in the Sacramento
-San Joaquin Delta, a major source of drinking water for more than 23 million people in California, USA. Studies are being conducted to isolate and characterize soil organic C of high propensity to form disinfection by-products during drinking water treatment with chlorine-based disinfectants. These studies may help improve treatment strategies for source water of high organic carbon or lead to development of water management strategies to reduce organic C influxes to Delta channels.
