Coastal Hydrogeochemistry Facility

 / Services / Laboratory Facilities / Coastal Hydrogeochemistry Facility


The Coastal Hydrogeochemistry Facility is a NABL accredited laboratory, for analysis of water chemistry from the coastal and marine systems of India. This facility is equipped to perform diverse chemical analyses including cations, anions, salts, alkalinity, and dissolved organic carbon. High standards of quality control are maintained with inter calibration exercises at regular intervals. A dedicated weighing balance room, room for laboratory consumables, chemical storeroom, and walk-in-cold room (4°C) are attached to the Coastal Hydrogeochemistry facility. This national facility is equipped with good ventilation systems, environmental controls, laboratory chemical hoods, safety controls, and other exhaust devices associated with the highly sophisticated instruments.

Analytical Capabilities:
  • Inorganic analysis of water samples
    surface water, seawater, pore water, drinking water, waste water, and ground water
  • Waters: pH, alkalinity, conductivity, total carbon, total nitrogen, silica, phosphate, ammonium, total nitrogen, sulphate, nitrate, chloride, bromide, SRP (soluble reactive phosphorous), total dissolved phosphate, calcium, magnesium, potassium, sodium, iron, manganese
  • Sediment: pH, salinity, phosphorous, phosphate sorption index (PSI), mineralisable N


  • Sediment and water nutrient dynamics
