Monitoring Water Quality in Ballona Lagoon, Los Angeles, California: Nitrate Level Fluctuation in Low and High Tide Condition

The coastal wetland, Ballona Lagoon in Southern California has experienced degradation and size reduction due to urbanization. This study analyzes nitrate concentrations the lagoon identify contamination sources assess its impact. includes determining levels during high low tides wet dry seasons, establishing concentration gradients, examining relationship between salinity concentrations. were found be higher locations closer head of lagoon, particularly urbanized areas, suggesting land-based season’s tide (S2: 2.37 mg/l; S3: 3.85 S4: 3.91 mg/l). Findings highlight importance managing near urban areas. Monitoring over time are crucial for sustainability efforts. research emphasizes need long-term monitoring conservation strategies mitigate Lagoon.
