Lead in Drinking Water

Confirming service line materials throughout an entire system requires field veri­fi­ca­tion programs, which take time and resources to complete. However, predictive modeling focuses leveraging information collected in the field  to understand  patterns for the rest of the system and predict the material of unknown services.

To have an accurate and reliable model, you need a solid team: water system engineers, GIS pros, data scientists, and computer scientists create an all-star predictive modeling lineup. Trinnex’s leadCAST Predict has assembled a team to help water systems accelerate the clas­si­fi­ca­tion of unknown service lines and prioritize field veri­fi­ca­tions through advanced material predictions powered by machine learning and other predictive modeling methods.

Predictive modeling is ever-evolving, and some state authorities have provided guidelines allowing its use to accelerate the inventory process.

Trinnex and CDM Smith are in discussions with the EPA and state regulatory agencies across the country to share best practices and provide education around predictive modeling for service line inventory development. If you are not sure whether your state will accept predictive modeling, reach out to us! If we haven't already, we'd be happy to engage with your state regulatory agency.
