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…

Measuring Acidity of Natural Water by Titration

In the past 75 years, the worldwide human population has increased from approximately 2.5 billion to over 7 billion people. Population increase, the resulting increase in use of natural resources, and anthropogenic (human) produced waste have significantly impacted our natural environment. One of the most vital resources that humans require to live is water. Ironically…

Environmental Monitoring of Nitrates and Other Water Quality Parameters: pH, Dissolved Oxygen (DO), Turbidity

Nitrate is one of the most important parameters in assessing surface and ground water quality. Nitrates are naturally present in surface and ground waters in low concentrations, but are harmful to humans and livestock and cause aquatic ecosystem degradation in high concentrations. Nitrates enter the environment as human-induced pollution from a variety of sources, but…
