Based on the data provided, the general water quality of this body of water appears to be declining.
One piece of evidence that supports this conclusion is the increase in nitrate levels in the water over the past three years. Nitrate levels have increased from 8 mg/L in 2018 to 12 mg/L in 2020. High levels of nitrate can lead to contamination of drinking water and can also contribute to algal blooms and dead zones in aquatic ecosystems.
Additionally, the increase in turbidity levels also suggests a decline in water quality. Turbidity levels have increased from 5 NTU in 2018 to 10 NTU in 2020. High turbidity can indicate sediment runoff and pollution in the water, which can harm aquatic organisms and disrupt the ecosystem.
Overall, the data indicates a trend of increasing contamination and pollution in the body of water, suggesting that the water quality is declining.
