- B Iron and manganese are minerals that are naturally present in untreated water. Specifically, iron causes water to appear red, while manganese leads to black stains. An SMCL is not enforceable, and testing for iron and manganese is voluntary. Again, SMCLs are for contaminants that are not a threat to human health. In contrast, drinking water contaminants that pose a health risk fall under a more stringent set of requirements: Maximum Contaminant Levels MCL. An MCL is the maximum allowable concentration of a drinking water contaminant.
Practice Exams: Water Treatment Operator Certification By Ken Tesh (2021, Trade Paperback)
They are mandatory and enforceable. Furthermore, all public water systems must comply with the MCL to protect public health. They are not voluntary. Arsenic and nitrate are examples of drinking water contaminants that are hazardous to human health, and have an MCL. C First of all, the water temperature of a lake differs as you move deeper in the water. The sun causes the upper layer to be warmer than the lower depths. As the upper layer heats up, the water density decreases. Meanwhile, the water in the lower depths remain cold and dense.- As a result, the difference in density minimizes the vertical mixing in the lake. When this occurs, the lake is thermally stratified. The water temperature differs as you go deeper. A lake that is thermally stratified has 3 layers. Most noteworthy, the middle layer has the biggest temperature decrease with depth. The lake remains stratified until early winter, when the surface water cools, and mixing begins. Consequently, the water temperature during winter is fairly similar throughout the entire depth.

- D First of all, a facultative pond has an aerobic layer in the upper portion, and an anaerobic layer in the lower portion of the pond. The aerobic layer contains oxygen, while the anaerobic layer does not. This question is regarding the upper aerobic layer. In the upper layer, algae uses sunlight as a source of energy to consume carbon dioxide in the wastewater to produce oxygen. This process is called photosynthesis, which provides oxygen to the microorganisms to treat the wastewater. During the day, with the presence of sunlight, this process increases oxygen in the pond. Towards the end of the day, there is a lot of oxygen available due to the algae. In contrast, a different reaction occurs at night because of the lack of sunlight. Oxygen is no longer produced by the algae. Instead, the algae consumes oxygen, and releases carbon dioxide. So, an opposite reaction takes place at night. Therefore, at sunrise, there is less oxygen in the pond because it is consumed by the algae during darkness.
- Furthermore, as a new day starts, the oxygen content in the wastewater increases again because the algae is using the sunlight to consume carbon dioxide and release oxygen. To clarify, this cycle repeats itself everyday. During the day, algae releases oxygen. C Dissolved oxygen DO is lowest at sunrise because the algae consumes oxygen and releases carbon dioxide during night-time and the dark, early morning hours.

This process is called respiration. Without the presence of sunlight, the oxygen in the pond becomes depleted due to the algae. We briefly discussed this earlier, in the answer to Question 1. However, when the sun starts to rise, the algae will begin to use the sunlight to consume carbon dioxide and release oxygen. This increases the oxygen level in the pond. At the end of the day, there is a lot of oxygen available. This process is called photosynthesis. In contrast, at night, algae consumes oxygen. When this ratio increases, it means that the acidity in the digester is increasing, which is a bad sign. In general, you want to avoid an acidic environment in the digester because it leads to upset. Otherwise, we will encounter operational issues.- Once you are logged in you can return to this page to link directly from the exam links listed below to the store for purchase or search the online store.
