Going from bad to worse... A matter of weeks ago the stretch of the River Thames at Ham and Kingston designated as a bathing water was reporting E coli levels 6 times over the legal limit, now blue-green algae has appeared.
Short version, stay the hell out of the river.
Warning - blue-green algae detected ⚠️
The Environment Agency has confirmed the presence of potentially toxic blue-green algae in the River Thames in and around the designated bathing water site at Ham and Kingston.
