How is the performance of a mound system primarily evaluated?

The performance of a mound system is primarily evaluated by monitoring effluent quality because this method provides direct and quantitative data regarding the system's effectiveness in treating wastewater. Effluent quality assessments can measure various parameters such as biochemical oxygen demand (BOD), total suspended solids (TSS), nutrient levels, and pathogens, which are critical for determining if the system is functioning properly and meeting regulatory standards. This ongoing monitoring helps to identify issues related to system performance, such as clogging or insufficient treatment, allowing for timely intervention if necessary.

While other factors such as system age and materials used, visual inspections, and soil temperature can provide some context or indirect indicators of performance, they do not offer the same level of concrete information about the treatment efficacy of the mound system. Monitoring effluent quality is rooted in environmental health as it is essential to ensure that the treated wastewater is safe for discharge and protects public health and the environment.
