Final answer:
When checking waste and water levels, you look for clarity, dissolved particles, pH levels, and solid particles.
Step-by-step explanation:
When checking the waste and water levels, you are looking for several things. First, you want to observe the clarity of the water by looking for any particles or impurities. You can do this by holding a water sample to the light and examining it. Next, you can use a microscope to examine the water samples more closely and look for any dissolved particles or other substances.
Additionally, you can test the pH of the water samples to determine their acidity or alkalinity. Finally, you can pour some of the water from each sample through filter paper to see if any solid particles are caught in the filter.
Electric water level meters – referred to as sounders – are frequently used in groundwater to measure level. These instruments are essentially tape measures with a probe on the end. Once the sensor contacts the water, it completes a circuit, causing an indicator to beep and an LED to glow.
