《GB/T 41837-2022温泉服务 温泉水质要求》由TC264（全国服务标准化技术委员会）归口，TC264SC3（全国服务标准化技术委员会温泉服务分会）执行，主管部门为国家标准化管理委员会。
Introduction
Core technologies and innovations of the standard
As China's first national water quality standard specifically for hot spring services, it establishes a 115-item indicator system based on the water-rock interaction mechanism and adds 12 new hygiene indicators such as Legionella pneumophila detection compared to the GB8537 drinking mineral water standard. The technological breakthroughs are:
- Construction of a dynamic management system covering the groundwater circulation time (minimum 12h water replacement cycle)
- The first comprehensive health effect assessment model for hot springs (radon concentration ≥110 Bq/L has therapeutic effects)
- Establishment of a contact-exposure risk assessment matrix (children’s bathing time is halved rule)
Water quality index comparison system
| Classification | Hot spring water source | Bath pool water | Control range |
|---|---|---|---|
| Heavy metal limit | 0.5mg/L beryllium | Add 0.2mg/L aluminum | 50% tightening |
| Microbial control | No requirement | Legionella pneumophila shall not be detected |
Certification conditions for therapeutic hot springs
Sulfur spring identification demonstration
A hot spring has a total hydrogen sulfide of 5mg/L and is equipped with air detection equipment (the air inlet needs to be 20cm away from the water surface). The actual measured H2S gas phase concentration of 0.17mg/m³ meets the requirements of Clause 4.3 and can be used only after certification.
Implementation Guidelines for Water Quality Monitoring
| Regular sampling points | Set up a detection point for every 800m³ (diagonal point distribution principle) |
| Disinfection by-product control | Use the HCA index method to assess the risks of 36 chlorination disinfection by-products |
Operational recommendations
- Chlorine disinfection needs to maintain ORP＞700mV to ensure the sterilization effect
- Use chlorine dioxide detection method (pre-heating to 37±1℃)
