Optical brighteners and tryptophan fluorescence both rely on fluorescence sensing, yet they reveal very different aspects of water contamination. This article explains how combining both indicators helps utilities and environmental professionals better detect wastewater influence and biological organic pollution.

Accelerated soil erosion directly degrades water quality by increasing turbidity, nutrient loading, and pollutant transport into rivers and reservoirs. This article explores the environmental and economic impacts of erosion and highlights how AlpHa’s turbidity and ion sensors enable continuous, data-driven mitigation.
