At a glance

Imagine you are in charge of managing and administering a project to ensure the quality of water at a site near a landfill. You have been working at inspecting the area to ensure there has been no contamination or discharge into the near-by water. You are a water and water and wastewater technologist ensuring the quality of water in the surrounding area meets certain standards.As a water and wastewater laboratory technologist, you are responsible for developing plans for monitoring water and wastewater quality. You sample, monitor, test, and analyze water and wastewater according to industry standards. Testing is done before, during, and after treatment. Water analysis will require efficient use of sampling and monitoring equipment and analytical instruments. Finally, you generate water quality reports based on your analysis of the water data.You work requires you to work in many different environments. You spend time in the field operating equipment used to monitor the water and wastewater. You are often in the lab, analyzing your data and samples. You also spend time in the office managing projects and writing reports. When each day comes to an end, you feel good about ensuring water quality.
