Water Quality Testing

With the development of society, environmental issues are becoming more and more prominent, and since the promulgation of ISO14000 series standards, a boom in testing and certification has been set off immediately at home and abroad, and the environmental awareness of enterprises is increasingly strengthened.

HCT has rich experience and high reputation in soil, air and noise testing, and can conduct professional testing for ambient air quality, soil environmental quality, domestic drinking water, industrial waste gas, industrial wastewater, domestic wastewater, fisheries wastewater and agricultural irrigation water according to ISO14000 standards and various international and domestic industry standards.

We treat all samples seriously according to different enterprise customer types and testing needs, and test the water quality of wastewater, groundwater, surface water, deionized water, cooling water, drinking water, etc. in strict accordance with the USEPA method, the Chinese national standard (GB) method, the Japanese Industrial Standard (JIS) method and other testing methods.
