7 PFAS Compliance Gaps That Inline Sensor Networks from Shanghai ChiMay Help Utilities Close Introduction PFAS compliance is not simply a matter of installing treatment equipment and checking boxes on a monitoring schedule. Water utilities face multiple gaps in their compliance programs, from insufficient monitoring frequency to poor treatment process visibility to inadequate data integration….
Why Reservoir Intake Turbidity Demands Continuous Monitoring Reservoir intakes are the first line of defense in drinking water treatment. Raw water turbidity at the intake sets the loading on coagulation, flocculation and filtration. When turbidity spikes—storm-driven sediment runoff, wind-induced sediment resuspension, a collapsing algal bloom—the plant has to respond immediately to keep filtered water inside…
The Economics of Intake Depth Selection Most drinking water reservoirs are equipped with multi-level intakes—typically 3–5 intake bells at different depths, allowing operators to select the source depth for raw water pumping. Despite the significant water quality variation across depths, many utilities operate their intakes at a fixed depth year-round, missing the opportunity to draw…
The Escalating Cyanotoxin Threat to Source Water Cyanobacteria have been around for over 2.5 billion years, but nutrient enrichment — nitrogen and phosphorus from agricultural runoff and wastewater discharge — has dramatically accelerated their spread. The result: cyanobacterial harmful algal blooms (cHABs) producing cyanotoxins — microcystins, cylindrospermopsin, anatoxins — that are a health concern at…
The Contamination Detection Challenge Source water reservoirs face a long list of contamination threats: Industrial chemical spills: accidental releases from upstream manufacturing, transportation accidents on roads crossing the watershed Agricultural chemical runoff: pesticide and fertilizer wash-off during storms from surrounding farmland Wastewater system overflows: combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) reaching the…
Why Are More Utilities Installing Continuous Dissolved Oxygen Monitors During Drought Events? Insights from Shanghai ChiMay Drought events trigger a chain of water-quality consequences that catch many utilities unprepared. Among the most disruptive is the collapse of dissolved oxygen levels in source water reservoirs and rivers. As water levels drop, temperatures rise, and stratification intensifies,…
