Abstract
Stormwater runoff from urban areas is a major
source of many pollutants to water bodies. Suspended
solids are one of the main pollutants because of their
association with other pollutants. The objective of this
study was to evaluate the relationship between suspended
solids and other pollutants in stormwater runoff in the city
of Tijuana. Seven sites were sampled during seven rain
events during the 2009–2010 season and the different
particle size fractions were separated by sieving and filtration.
The results have shown that the samples have high
concentration of total suspended solids, the values of which
ranged from 725 to 4,411.6 mg/L. The samples were analyzed
for chemical oxygen demand, total phosphorus, total
nitrogen, and turbidity. The results show that most of the
particles in suspended solids are in the particle fraction
between 10 and 62 μm. A high association between the
concentrations of suspended solids was found for chemical
oxygen demand, phosphorus, and turbidity but not for total
nitrogen.
