| Beach samples from the Belgian coast and the Nieuwpoort Channel have been examined for (a) coliform and other common bacteria and (b) more serious pathogens, to determine from their distribution the influence of season, tide, presence of human and other animals and of effluent. There were more coliforms in summer than in spring. State of tides had no significant effect on coliform numbers. The dry sand above HWM, occupied by holidaymakers, was as polluted as intertidal sand. Sand in the Channel near a sewage outfall was rich in coliforms. <i>Salmonella paratyphi </i> B was also found, but no <i>Shigella</i> spp., although <i>Shigella phages</i> were present. |

| A solution of one hundred kilograms of B rhodamine was introduced in a sewer which discharges into the sea. The dispersion of the discharge was observed and located by means of 4 optical theodolites and by air photographs. Water samples were collected in the coloured plume and on its boundaries during a whole tidal cycle. They were analysed by spectrofluorimetry. The results demonstrate the complexity of the factors that affect water movements. The drift seems to be mainly due to the wind. The predominating winds contribute to maintain the waste water closely to the water line over a distance of several miles. |
