Fresh baking powder typically has a neutral or slightly tangy smell.
The pH level of fresh milk typically ranges from 6.5 to 6.7, making it slightly acidic.
Fresh water is considered neutral with a pH around 7. However, the pH of fresh water can vary slightly depending on factors such as the presence of minerals and organic matter.
Fresh water refers to water with low levels of salinity, typically found in rivers, lakes, and groundwater sources. Clean water, on the other hand, refers to water that is free from pollutants, contaminants, and impurities. Fresh water can be clean if it is free from contaminants, but not all fresh water sources are necessarily clean.
The pH of fresh groundwater can slightly decrease upon exposure to air due to the absorption of carbon dioxide from the atmosphere. Carbon dioxide can dissolve in water to form carbonic acid, which lowers the pH of the water. This process is known as carbonation and can lead to a slight decrease in pH levels.

fresh groundwater
Ground off and runoff are both precipitation and fresh water. Since they are fresh water, people use groundwater and runoff for households and drinking waters sometimes.

it is called groundwater
Approximately 30% of Earth's fresh water is frozen in groundwater. This groundwater is stored in underground aquifers, which provide a crucial source of freshwater for drinking and irrigation.
groundwater can be fresh, or can have various salts and/or minerals dissolved in it
Groundwater can be either saltwater or freshwater, depending on the location. In coastal areas, groundwater can be saltwater due to seawater intrusion. Inland areas typically have freshwater groundwater sources.
