Water Distribution System Water Quality
The quality of water in municipal water distribution systems, once taken for granted in the United States, is increasingly the subject of careful monitoring and analysis. Contamination by potentially toxic industrial chemicals has led to high-profile litigation, bringing arcane engineering science into the popular literature and even movies. Moreover, the evolving security environment has led to heightened concern about the detection of, and response to, intentional contamination. Natural by-products of disinfection are also under increasing scrutiny. Hydrosphere has a nationally recognized capability for simulating water quality conditions in water distribution systems. We have adapted the widely accepted simulation code EPANET to make long time-series simulations, some extending over decades. These long simulations are necessary to fully represent the dynamic conditions in a water distribution system. Our work in this area was pioneering and has been described in conference presentations and journal articles and has been thoroughly scrutinized in litigation.
