This post shares the importance of nitrate and pH levels in the calculation of water quality. Nitrates are organic compounds found all around us while pH can be influenced by nitrate levels or human contaminants.
Temperature and dissolved oxygen are just two of the many factors scientists study when determining water quality. Temperature measures how hot or cold the water is, and dissolved oxygen measures the percentage of oxygen dissolved in a given volume of water. Scientists use both of these as an indicator of contaminants or abnormal activity in a body of water.
