    It's common enough, unfortunately. Usually following a short period of very heavy rain. Slurry and sewage get washed into water courses and show up in the sea. After a week or so it disperses so you see these spikes in coliform levels.

    Beaches get closed for a while and open up again once the tides have diluted the danger.

    By comparison I saw a program on the Ganges where the ecoli levels were over 5 Million per 100ml in Varanasi.

    Correct me if I'm wrong, but isn't it also the case that because our grey water (road water run off, shower water etc.) isn't separated from fecal contaminated waste water, such as it is in France etc. that after heavy rain our waste water treatment plants simply get overwhelmed and pump human waste untreated a far too short a distance out to sea?

    This is mostly the case. Many towns have combined lines which take in rainwater. This has slowly been changing though, and all modern estates should have seperate storm lines and drains as should most roadways.

    When there is extreme rain the plants simply cannot cope with the added volume of water. There are storm tanks which quickly fill and then the water/sewage has nowhere to go except out to the waterways, untreated. At this point it is well diluted but sewage is present all the same.

    Its the reading week 28/08/17:
    Ecoli 2143, yet in the same sample Enterococci 9.
    Does that make any sense?

    In various parts of the country, yes. To be fair, though, there has been a major infrastructure upgrade in Sth Dublin in recent years so that shouldn't be the case in Sandycove.
