    chlorine, or chlorine equivalent of hypochlorite. There are   
    chlorine content measurement kits,   
   using chlorine reaction developing a yellow dye, comparing with   
    colour charts.

   Not possible without  a lab equipment.   
      
   Procedurally, water is striped out of dissolved CO2 and carbonates   
    by  addition  of hydrochloric acid and by purging with CO2 free   
    nitrogen.   
   Then, water sample is injected to a furnace with a NiO catalyst,   
    where organic matter is oxidised to CO2.   
   Current equipment usually uses IR absorption measurement of CO2,   
   být the one we used in early 90s   
   used reduction CO2 by H2 to CH4   
   and measurement of methane content by flame ionisation detector.
