In recent years, national water quality monitoring has significantly improved. More cities actively and regularly disclose water quality data, and the scope of disclosures has expanded: local departments now publish data not only from monitoring points managed by the national government, but also from those managed by provincial, municipal and county-level governments. The content of these disclosures has also increased in detail, from general descriptions of local water quality conditions to the full disclosure of comprehensive monitoring data. The Measures for the National Water Quality Monitoring Information Disclosure for Centralized Drinking Water Sources ensures that water quality information for centralized drinking water sources is published on track. The Action Plan for the Prevention and Control of Water Pollution issued by several provinces and municipalities also discloses the status of groundwater quality.
