Risk Assessment
Quantitative microbial risk assessment (QMRA) and quantitative chemical risk assessment (QCRA) play a crucial role in protecting human health in the water cycle. From water and wastewater treatment to managed aquifer recharge and bathing waters, these assessments evaluate the risks that can arise from different types of exposure. QMRA can assess whether treated wastewater meets safety standards by modelling the removal of pathogens like bacteria, protozoa, and viruses. Meanwhile, QCRA helps identify and manage chemical contamination to maintain water quality and protect public health.
Whether performed in a qualitative, semi-quantitative, or quantitative manner, these assessments rely on available data. Probabilistic modelling accurately captures the uncertainty in risk assessment, providing valuable insights for economically viable, safe, and sustainable water and wastewater treatment systems. Together, these assessments form the backbone of a comprehensive approach to water management, protecting the environment and human health.
