One、Water quality standards for drinking water dispensers
Currently, there are no specific water quality standards for water dispensers. However, the publication of the "Health Standard for Drinking Water" (hereinafter referred to as "the Standard") for the first time defines healthy drinking water and specifies water quality standards. Several indicators in the Standard are stricter than the drinking water quality standards of WHO, Japan, the United States, and the European Union.
"The standard clearly states that healthy drinking water is tap water or water from a source that meets the standards for potable water, after appropriate treatment to achieve a certain level of mineralization, and complies with both national food safety standards and the requirements of this document, making it suitable for direct consumption.
"The standard sets limits on 3 key indicators (dissolved total solids (50~300 mg/L), total hardness (25~200 mg/L), and total organic carbon TOC (≤1.0 mg/L)) and 3 microbial indicators, as well as 19 limit indicators, under the condition that it meets the requirements of the "National Standard for Drinking Water Quality (GB5749)" and the "Drinking Water Quality Standard (CJ94)."
Two. Does the water quality from the community's drinking water reach the required standards?
Under normal circumstances, the water quality from the community's direct water supply is compliant with standards.
What is the normal situation? This primarily involves checking the water dispenser in the community, determining if someone regularly inspects and maintains it, whether replacement filters are regularly performed, and ensuring the area around the water dispenser is clean and hygienic.
Regular inspection and replacement of filters are essential for ensuring that the water quality of the water dispenser meets standards, maintaining the external environment, and preventing contamination of the water after dispensing.
