Which parameters are typically measured in wastewater effluent?

The selection of parameters typically measured in wastewater effluent is essential for assessing the quality of the treated water before it is discharged. Biological Oxygen Demand (BOD) indicates the amount of organic matter present, which is crucial for understanding the potential impact on aquatic life. Total Suspended Solids (TSS) measure the solid particles in the effluent, which can affect water clarity and habitat for aquatic organisms.

pH is critical because it impacts the solubility of heavy metals and the efficacy of disinfectants used in treatment processes. Additionally, nitrogen levels, including ammonia and nitrates, are monitored due to their potential to cause algal blooms and affect the overall water quality. Fecal coliform levels serve as an important indicator of potential pathogenic contamination, making it vital to assess public health risks.

Collectively, these parameters provide a comprehensive overview of the effluent's impact on the environment and help ensure compliance with regulatory standards.
