The WELS water rating label. There are three parts to the label: The star rating at the top shows the water efficiency of the product. The more stars, the more water efficient. The water consumption rate in the middle shows the amount of water used. The company name and the WELS license number are at the bottom.
The agency with the lead implementation responsibility for most major federal environmental laws (e.g. Clean Air Act, Clean Water Act) is the US Environmental Protection Agency (EPA).

Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
The five offices that achieved the highest satisfaction in interior design, indoor air quality, privacy and connection to the outdoor environment were WELL-certified. [9] No significant differences in health were found between WELL-certified and non-WELL certified buildings as quantified by questions about physical and mental health presented ...
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
