For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardised, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.

The clock is ticking for water utilities across the nation. With federal compliance deadlines for PFAS and other contaminants of emerging concern looming on the horizon, the municipal water sector is facing an unprecedented wave of operational and regulatory pressure. Are communities truly prepared for what’s coming, or are they waiting too long to act?
In this on-demand webinar, Ecolab introduces the next-generation PRSM™ Softening Calculator, a powerful and free tool built to help water professionals evaluate system designs, optimize operating conditions, and clearly quantify total value delivered (TVD).
As utilities worldwide race to modernize, advanced metering infrastructure (AMI) has emerged as one of the most talked-about — and often misunderstood — investments in the water sector. In this episode, our hosts are joined by SWAN members Shirley Ben-Dak and Richard Relyea to discuss insights from the SWAN Global Smart Metering Playbook — unpacking why getting meters installed is only the beginning.
CLOSING THE GAP: A MODERN PLAYBOOK FOR NON-REVENUE WATER
Reducing non-revenue water (NRW) is no longer just an operational goal; it’s a strategic imperative that directly affects asset life, service reliability, affordability, and public trust. This e-book on NRW is intended as a practical guide for utilities ready to take the next step — from managing water loss to controlling it.
