Part 3. Turbidity Turbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. This is primarily caused by suspended solids. The higher the turbidity, the greater the amount of scattered light. Even a very pure fluid will scatter light to a certain degree; no solution will have…

Monitoring Water Quality

Part 2. COD and BOD Properties of water bodies vary based on natural factors such as landscape position and slope, watershed size, geology, and soil composition, as well as man-made pollution. Before a water source can be used for human, animal, or plant consumption, it must be assessed and possibly treated to make sure it…

Chemical Oxygen Demand (COD) in Caustic Wastewater

Testing the wastewater at any manufacturing site is paramount in ensuring the water released into the waste stream meets the required standards. If the quality of effluent water does not meet predetermined standards, hefty fines can be issued by local, state, or federal regulatory agencies. In food manufacturing, large amounts of organic waste are produced.…

Using the Backpack Lab™ Marine Science Test Kit in Education

Oceans are some of the most important natural resources in Australia providing commercial, environmental, and intrinsic values. Oceans provide 10% of human protein consumption in the form of fish and shellfish, are one of the world’s largest carbon sinks which helps mitigate increased atmospheric CO2 levels, and provide educational and recreational values. However, as human population…
