Testing - Environmental Analysis
A healthy and quality life starts with a clean and safe environment. At STC, we provide environmental surveillance and testing on air quality, water quality, plastics, and various types of trace chemicals and pollutants to assess their quality and impacts on health and the environment.
Water is the essence of life and we places great emphasis on the quality of water through our extensive water quality testing services. Acquiring HOKLAS accreditation for tap water, drinking water, cooling tower water testing and more, our environmental analysis team can identify chemical, physical and microbiological parameters with reference to WHO, BP and GB standards to ensure safety compliance.
Additionally, the emission of hazard substances into the air such as volatile organic compounds (VOCs) and formaldehyde have also become an increasing concern for public health. STC’s experienced chemists and state-of-the-art VOCs chambers can access and detect even trace amounts of hazardous substances in building materials, furniture, and home decorations.
Our Environmental Surveillance & Analysis services include:
