Measuring water quality in our lakesCharlotte-Mecklenburg Storm Water Services collects water samples from local lakes six times a year. There are 28 monitoring sites on the lakes that are sampled each time.The data are grouped into categories that show the most troublesome pollutants and indicators of environmental health. Using the data, Storm Water Services creates the LUSI maps, tracks trends in lake water quality, and pinpoints specific water quality problems.
We check: • Water temperature• Dissolved oxygen (can the fish breathe?)• Conductivity (the chemical makeup of polluted water allows electricity to flow through it more easily)• pH (is the water acidic, alkaline or neutral?)• Turbidity (how murky is the water?)• Chlorophyll, Total Phosphorus, Nitrate-Nitrogen (any algae blooms?)• Fecal coliform bacteria (any sewage spills affecting the water?)• Toxic metals (hazardous to fish and other aquatic life)• Volatile Organic Compounds (such as petroleum additives that pollute waterways)
Storm Water Services also tracks water quality in our streams. How we test water quality in our streams and lakes See a video of Storm Water Services staff testing lake water quality Request water quality data Protecting the Water Quality in our Lakes (booklet)
