Grant

• Characterize spatial and temporal variability of manganese (Mn) concentrations and speciation in distribution systems and potential impacts in premise plumbing.
• Investigate Mn speciation and its influences on interactions with water chemistry, corrosion control treatment, and complexing agents, and assess implications for Mn occurrence, stability, and release in distribution systems and premise plumbing.
• Evaluate the relationships between Mn stability and release, including long-term legacy deposit mobilization, in relation to chemical, hydraulic, and biological processes in distribution systems.
• Evaluate strategies for mitigating Mn accumulation and release, including corrosion control treatments such as phosphate blends, and assess operational practices such as flushing and other system maintenance activities.
• Recommend monitoring strategies to identify system-specific risks, support detection of Mn accumulation, and inform responses to anticipated regulatory changes.
