The scienceSummer season monitoring
LAWA shows the best available water quality information to help you decide where to swim. For many sites there are two types of information available, the weekly sampling result and the long-term grade.
Water quality test result
Current Enterococci statusNo recent dataThe weekly sampling result is a snapshot in time, and is a guide to the recent water quality at this site.
Long-term grade
Long-term Enterococci gradeNot availableLong-term grade is important to consider. Based on 5 years of data, it is a guide to the general water quality at this site.
Reminder
Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for 2 – 3 days after heavy or prolonged rain – even at sites that generally have good water quality. Check that the water is clean and clear before taking a dip.
