Because humans have such strong physical and emotional connections to water in the environment, it follows that individuals and groups will have strong ideas and expectations of that environment that must be related to visible features. Optical water quality describes the scattering and absorption of light in water as governed by its dissolved and particulate composition. Mineral suspended sediment, dissolved organic matter, and living and nonliving particulate organic matter have different influences on the behavior of light in water. The physical sciences endeavor to define variability in water quality, be it natural or anthropogenic, for use in water resource management. However, a more holistic approach to water resource management is becoming increasingly advocated, which requires investigation of the human dimension. The directly visible attributes of color and clarity of water are among the strongest influences on human perceptions of water quality. The observed environment is perceived through cognitive processes that are defined by spiritual and cultural beliefs and evolve with personal experience, creating the mental model. Water color and clarity can provide a critical link between water quality and human perceptions. Ethnohydrology is the study of culturally constructed knowledge and understanding of water. An interdisciplinary approach, integrating optical water quality measurement and ethnohydrology methods, may help achieve better awareness, communication, participation, and support in water resource management and sustainability endeavors.
