 Site Work Recommendation Form Name: Aya Alghazi Email: [email protected] Please fill in the corresponding data collected in South America: Site A Control Site Acceptable Levels Nitrate Levels 0.75 0.35 below 1 mg/L (SNHU University, 2022). pH 6 7 6.5 – 8.5 (SNHU University, 2022). Turbidity 40 1.0 0.5 NTU – 1.0 NUT (SNHU University, 2022). Written explanation: When looking at the experimental data for fresh water, which includes the results of the tests (for the level of nitrates, pH, and the level of turbidity) at site A and the control site, and then comparing them with the natural level for it We find that the level of nitrates in site A is 0.75, while in the control site it is 0.35, but the acceptable levels are 0.1 - 4 mg / liter. The level of nitrates in some sewage plants is at levels higher than 20 mg / liter, and this means that there is a difference in the result. For the pH, it is 6 in the A site, while it reaches 7 in the control site. As for the natural levels, it is 6.5 - 8.5. Any slight change in the pH poses a threat to several species because their survival and reproduction are linked to a certain number, but a ratio such as six is considered harmless directly to fish, provided that free carbon dioxide is low. As for turbidity, its level in site A is very high. 40) While it is in the control site only 1.0 and its normal ratio is 0.5 NTU to 1.0 NTU (SNHU University, 2022).  Negative impact of water pH levels on local populations and wildlife:
