Charlotte-Mecklenburg Storm Water Services utilizes a variety of monitoring techniques to fulfill its Water Quality goals:

1.    Fixed Interval Monitoring (FIM): Grab samples and field data collected monthly at specific stream monitoring sites on a fixed interval, such as the 10^th day of every month, regardless of weather conditions.
2.    In-Stream Storm Water Monitoring (ISM): Flow weighted composite samples and field data collected monthly at specific stream monitoring sites during storm water flows using automated samplers.
3.    Lake Monitoring: Grab samples and field data collected monthly at specific lake monitoring sites during base flow conditions.
4.    BMP Monitoring: Flow weighted composite samples and field data collected monthly at the influent and effluent of specific structural BMPs during storm water flows using automated samplers.
5.    Biological Monitoring: Benthic macroinvertebrate and fish samples collected annually at specific stream monitoring sites.
6.    Continuous Automated Monitoring (CMANN): Data collected hourly for pH, temperature, dissolved oxygen, conductivity and turbidity using remote automated monitoring equipment that transfers data to a website via modems.  Get CMANN data.
