Water Testers often work in diverse environments, from treatment plants to natural water sources, which can present challenges such as difficult terrain, inclement weather, and ensuring sample integrity during transport.

What is a water tester?

A water tester works under the guidelines of EPA standards to test water quality at waste treatment plants and throughout freshwater systems. You do this to promote and protect the public health. As a water tester, your duties are to take samples of water from a plant and test its quality using specialized skills and equipment. Your goal is to test the levels of harmful materials and chemicals in the water supply through biological sampling and chemical testing. Your responsibilities are incredibly important because of the threat to public health that improper testing of chemicals in our water systems can cause.

What are the key skills and qualifications needed to thrive as a water tester, and why are they important?

To thrive as a Water Tester, you need a solid understanding of environmental science, chemistry, and water quality standards, often supported by a relevant degree or certification. Familiarity with laboratory testing equipment, water sampling procedures, and data analysis software is essential. Attention to detail, strong organizational skills, and effective communication help ensure accurate results and clear reporting. These skills are crucial for maintaining public health and environmental safety by ensuring water sources meet regulatory standards.
