Title: St Columb Major STW UV disinfection survey 1994 : final draft report
Author: Tim Geatches
Document Type: Monograph
Non-compliance at Mawgan Porth EC bathing water was recorded in 1986, 1987, 1989, 1990, 1991 and 1993. The River Menalhyl flows out onto Mawgan Porth beach and is considered the major source for bathing water non-compliance. St Columb Major STW final effluent is the major discharge within the Menalhyl catchment although previous work has shown diffuse sources within the catchment may be as important. Because of bathing water failure South West Water Services Ltd installed ultra violet disinfection to the final effluent during the summer of 1994 for a trial period. St Columb Major STW final effluent has always been considered a factor in Mawgan Porth bathing beach failure. Therefore, it was requested by Tidal Waters Quality to assess the effect of the UV disinfection on bacteriological quality of the River Menalhyl.
