Well yes, I mean you must allow for a woman who now identifies as male.

I took heed of the warnings, first sat in the sun, then had a pint, then jumped into cold water risking thermal shock and a heart attack. No sewage discharges in Mount's Bay, but I see SW Water are currently pumping sewage into the sea (via storm?! overflows) at the 2 busiest beaches in the far SW (Sennen & Porthcurno)over a bank holiday weekend. They are both lifeguarded beaches where people are encouraged to swim by the media and will be packed tomorrow. 

 

Information thanks to Surfers against Sewage. It's a very useful site to check before swimming in the sea.

I don't know where SAS get there data from. I have access to all the storm spills in the SW and the last one I can find was for Readymoney Cove on the 20th May during a rainfall event. Nothing since then up to today (27th). The only reports I'm getting are calibration of monitor events where the EDM (sensors) are taken temporarily offline for their annual calibration/check.

SAS get their data from various sources. TheSW Water official reports represent only a small fraction of actual sewage discharges. For instance SW water have worked on the pipes from Mousehole pumping station twice since the 'clean sweep' because they were leaking into Mount's Bay. None of this was reported by SW Water, it was by SAS.

There aren't many SW Water reporting points, so most sewage goes unreported by them. In addition they seem to miss storm overflows which are clearly visible to the naked eye. Not uncommon at Gwithian & St Agnes. Sometimes they even say the discharge was an error in the reporting system, when it was clearly real. On a few occasions SAS, and others, have got the press to film the sewage being discharged into the sea, which officially does not exist.

SAS do their own tests (as does the Jubilee pool before they pump in water from the sea to the pool). The SAS maps allow time for the sewage to disappate, normally 48-72 hours, which SW water does not (I think). Other sources are used to get an overall water quality idea. As an example https://datahq.sas.org.uk/citizen-science-data-hq/citizen-science-results/

Looking at that page you get details like this (coliform count)

I'm not saying the SAS map is 100% accurate I'm sure they are perfectly capable of  making an error. What I can say is it's probably the most complete picture you can get. At Porthcurno there was maintenance for 2hrs 24 mins on 20th May. Whether this is responsible for the report, I wouldn't know.
