  28. 28. Limitations/Constraints of Monitoring System •Site selection and Timely clearance/permission for installation • Frequent calibration • Security in remote areas • Wide variation in real time values in respect of some parameters (BOD,COD and Nitrate) however relatively reliable observations in respect of other parameters (pH, DO, Temperature, Colour, Conductivity, Turbidity, Chloride and Ammonia) •System is workable however drop time observed invariably due to communication failure or solar power disruption
  29. 29. What is next in Real Time Water Quality Monitoring? Water quality monitoring with a larger network is envisaged for grossly polluted river stretches Proposal for setting up of stations on various rivers along cities envisaged based on the latest experience System will be helpful for CPCB and SPCBs/PCCs struggling with manpower. Data purchase concept is being worked out and shall be such so that the vendors have opportunity to invest in setting up of RTWQMS.
  30. 30. What is next in Real Time Water Quality Monitoring? Ganga water quality monitoring with a larger network is envisaged -2014 onwards Limitations shall be huge investment and skilled manpower. Data purchase concept is being worked out and shall be such so that the vendors have opportunity to invest in setting up of RTWQMS.
  31. 31. What is next in Real Time Water Quality Monitoring? Industrial effluent quality monitoring on all the grossly polluting industries along river Ganga and its tributaries to cover entire basin area in four States in the first phase under National Ganga River Basin Authority. Entire Ganga Basin in 9 States to be covered subsequently. Industries have been directed to install Real Time Effluent Quality Monitoring system and transmit the data to CPCB and concerned SPCBs/PCCs.
