Pesticides associated with suspended sediments entering San Francisco Bay following the first major storm of water year 1996 Pesticides associated with suspended sediments entering San Francisco Bay following the first major storm of water year 1996
Estuaries receive large quantities of suspended sediments following the first major storm of the water year. The first-flush events transport the majority of suspended sediments in any given year, and because of their relative freshness in the hydrologic system, these sediments may carry a significant amount of the sediment-associated pesticide load transported into estuaries. To...

Trihalomethanes formed from natural organic matter isolates: Using isotopic and compositional data to help understand sources Trihalomethanes formed from natural organic matter isolates: Using isotopic and compositional data to help understand sources
Over 20 million people drink water from the Sacramento-San Joaquin Delta despite problematic levels of natural organic matter (NOM) and bromide in Delta water, which can form trihalomethanes (THMs) during the treatment process. It is widely believed that NOM released from Delta peat islands is a substantial contributor to the pool of THM precursors present in Delta waters. Dissolved NOM...

Carbon isotopic constraints on the contribution of plant material to the natural precursors of trihalomethanes Carbon isotopic constraints on the contribution of plant material to the natural precursors of trihalomethanes
The δ13C values of individual trihalomethanes (THM) formed on reaction of chlorine with dissolved organic carbon (DOC) leached from maize (corn; Zea maize L.) and Scirpus acutus(an aquatic bulrush), and with DOC extracted from agricultural drainage waters were determined using purge and trap introduction into a gas chromatograph-combustion-isotope ratio monitoring mass spectrometer. We...
