Too much algae in water can also affect a water’s ability to maintain a proper balance between being too acidic and too alkaline. The measurement of this balance is called pH. Aquatic life evolved in natural water systems where pH did not change quickly over short periods of time. Sudden shifts in water conditions due to pollutants can cause pH to shift too quickly, which can be harmful to aquatic life if such shifts occur too frequently. Heavy algal growth due to too many nutrients in water can cause pH to rise too high during daylight hours. On August 25, 2021, pH levels rose to 9.6 at 5:30pm, which exceeded the state of Louisiana’s pH water quality standard of 9.0 for Lake Pontchartrain, indicative of an algal bloom near the sensor.
