Water quality standards are essential criteria established by regulatory agencies to protect water bodies from pollutants and ensure the safety and health of aquatic ecosystems and human populations that rely on these water sources. These standards define the maximum allowable concentrations of specific contaminants and set guidelines for maintaining and improving the quality of water resources.

The focus of water quality standards is predominantly on the prevention of pollution, as they aim to establish limits on pollutants that can enter water bodies. This allows for the protection of aquatic life, recreational users, and drinking water sources, ensuring that water remains safe and conducive to various uses.

The other options, while related to water management and quality, do not specifically capture the essence of what "water quality standards" entail. Guidelines for recreational water usage primarily concern health and safety measures for human interaction with water, methods for measuring stormwater volume focus on hydrological aspects rather than quality, and protocols for wastewater treatment address the processes involved in treating contaminated water rather than setting standards for its quality in natural water bodies.
