Correspondence between the vertical distribution of total organic carbon (TOC) at station 3C (approximately 6-8 km downcurrent from the outfall system) and the mass emissions of suspended solids from the outfall system during the period 1946-1981 is illustrated in Fig. 6. Following World War 11 and up until 1971, the monotonic increase in emissions of suspended solids from the LACSD paralleled the population trend in Los Angeles. Thereafter, solids emissions declined in response to improved source control and advances in waste treatment (Stull et al, 1996). The vertical concentration profile of TOC in the 3C (1981) core records the historical trend in effluent solids emissions and indicates that, for this period, the outfalls dominated sedimentation of organic carbon on the shelf. The dechne in emissions of suspended solids from the outfalls after 1971 became a matter of concern because of the potential for remobilization of heavily contaminated sediments that had been laid down in earlier years.
