Question

what kind of standards does the epa establish for both drinking water and surface water? color standards quality standards temperature standards

Explanation:

The Environmental Protection Agency (EPA) is responsible for safeguarding public health and the environment. In the context of water, it focuses on ensuring that water (both drinking and surface) meets certain criteria to be safe and suitable for its intended uses. Quality standards encompass a wide range of parameters such as the presence of contaminants (like heavy metals, bacteria, chemicals), physical properties (e.g., turbidity which affects clarity and can relate to particle presence), and chemical properties (e.g., pH levels which affect water's acidity/alkalinity and can influence how chemicals interact in the water). These are comprehensive measures to protect human health (for drinking water) and the health of aquatic ecosystems (for surface water). Color standards are more about aesthetic or sometimes an indicator of certain substances (but not the overarching, comprehensive standards for safety and suitability like quality). Temperature standards can be relevant in some ecological contexts (e.g., for fish habitats in surface water) but again, they are not the broad - based standards that cover all aspects of what makes water safe (in case of drinking) or healthy (in case of surface water ecosystems) like quality standards do.

Answer:

quality standards
