ECOLOGICAL IMPLICATIONS OF AGING AND OBSOLETE WATER INFRASTRUCTURE
Many of the systems and processes ecologists study are strongly impacted, if not directly modified by, feedback between ecosystem properties and human behavior. Aging and obsolete water infrastructure is a critical, global problem threatening economic stability, human welfare, and the environment. Allocating scarce resources to maintain and upgrade water resource infrastructure is a challenge faced by countries throughout the world and this burden is frequently relegated to local governments. Failing wastewater treatment infrastructure presents a globally pervasive threat to the integrity of freshwater ecosystems. Nevertheless, we have a limited understanding of how waste streams vary in their pollutant load and how they may differentially effect ecosystem structure and function. Urban streams receive large quantities of wastewater delivered both intentionally and inadvertently. In addition to threatening human health, wastewater effluent entering freshwaters alters the flux of organic matter and biogeochemical cycling. However, we know relatively little about how sewage-derived energy and nutrients alter the structure and function of running waters. Here, I will present two case studies examining interactions between human waste streams and community structure and ecosystem processes in temperate and tropical streams.
