Ruth Patrick gauged water quality by examining the presence and diversity of certain types of organisms, such as diatoms and algae, in the water. These organisms are sensitive to changes in water quality, so their abundance and health can indicate the overall condition of the aquatic ecosystem. Patrick developed biological indicators and methods to assess water quality based on these organisms, pioneering the field of freshwater ecology.
Ruth Patrick gauged water quality by putting it on a scale.
Ruth Patrick gauged water quality by studying the species of algae present in a water sample. By examining the diversity and abundance of algae species, known as the diatom index, she could determine the pollution levels and ecological health of the water body. This method, known as the Biological Assessment Profile, revolutionized water quality assessment and management.

Ruth and I
Ruth would be able to see that the copper sulfate crystals had dissolved in the water by observing if the crystals disappeared completely and the water turned into a clear blue solution. This indicates that the crystals have broken down and mixed evenly with the water, creating a homogeneous solution.
Ruth would know that some of the copper sulphate crystals had dissolved in the water by observing if the water changed color to blue, which indicates that the copper sulphate dissolved. Additionally, she could check if there are fewer crystals at the bottom of the container, as they would have dissolved into the water. Ruth can also test by inserting a clean spoon and checking if any more crystals can stick to it, indicating that some have dissolved.
Ruth's Chris Steak House sources its meat from a variety of suppliers, focusing on high-quality cuts of beef. They typically use USDA Prime beef, which is known for its marbling and tenderness, and it is often sourced from well-regarded ranches in the United States. The restaurant emphasizes quality and consistency in its meat selection to ensure a premium dining experience.

In "The Color of Water" by James McBride, Shilsky is the Jewish man who works at the grocery store where Ruth, the author's mother, works. Ruth describes him as kind and caring, and he is one of the few people who treat Ruth well despite her being different from the predominantly African American community.
