Environmental Testing Laboratories

We understand the immense threat pollution poses to the environment and human health, especially in a world threatened by climate change. Environmental testing laboratories are more critical than ever for producing accurate, dependable data, using USEPA, ASTM, and other globally harmonized standards to protect our precious resources. Explore our methods and instruments for your laboratory.

Nutrient Pollution

According to the U.S. Environmental Protection Agency (USEPA), nutrient pollution is one of America’s most prevalent, costly, and challenging environmental problems. Determine nitrate, nitrite, TKN, total phosphorus, and more with our FS3700 platform and Gerhardt TKN digestion systems.

Biological Oxygen Demand

BOD is among the most critical parameters for the detection of wastewater and agricultural runoff in our waterways and is a parameter that is regulated in most regions of the world. YSI has the leading BOD probe in the industry, used on our MultiLab platform.

Total Organic Carbon

TOC is an important water quality parameter and one of the most monitored worldwide. Municipalities worldwide use our Aurora 1030W TOC Analyzer to determine TOC levels and analyze the effectiveness of their process.

Pesticide Analyses

Even trace amounts of pesticides can be harmful if found in food, water, and soil sources, making it extremely important to have sensitive, accurate, and dependable detection solutions. Our 5383 PFPD is the perfect instrument for USEPA Method 8141B to analyze organophosphorus (OPP) pesticides.

Cyanide Analysis

Cyanide is highly toxic and can result in substantial environmental impacts and public health risks if not adequately monitored. Luckily, our FS3700 measures cyanide with ease in accordance with USEPA OIA-1677-09, ASTM D7511, ASTM D6888-09, and more!

DBPs and THMs

Disinfection-by-Products (DPDs) in the form of Trihalomethanes (THMs) and Haloacetic Acids (HAA’s) result when organic carbon reacts with chlorine that is used for disinfection in the water treatment process. Organic carbon removal, monitored by both online and laboratory TOC determination, is critical for controlling DPD formation.

Reliable Results

All sampling applications require the collection of high-quality data, but the demand for accurate data is perhaps greatest in the laboratory setting. Confidence in laboratory results is paramount, as this data is used for EPA reporting of parameters such as biochemical oxygen demand (BOD) of wastewater. Lab-obtained data is also commonly used in wastewater process control and verification in addition to drinking water analysis, publication, clinical research, and many other applications.
