Marias

Managed by Surfrider Foundation - Rincon Chapter

Located on Puerto Rico's western coast, Marias Beach is a well-known destination for surfers. Marias has a shallow reef, and consistent waves for both new and experienced surfers. When the waves are big, currents tend to be very strong. Marias Beach got its name during the 1968 World Surf Championships when many people set up tents behind the house of local resident Dona Maria, whos name has stuck with the beach since. You can take surf lessons and rent boards here with local venders. There are two popular cafe/bars nearby, perfect for taking in the areas' famous sunsets. On the beach there is an area great for sunbathing, but be careful for hidden or slippery rocks. Marias is also a great place to find sea glass!

Monitoring Frequency

Source Information

Surfrider Foundation’s Blue Water Task force is a volunteer-run, citizen science initiative and water quality monitoring program. The Rincon Blue Water Task Force tests both marine and freshwater sites for enterococcus, a coliform bacteria that indicates fecal pollution. Testing is conducted on a weekly basis year-round. After the island was devastated by Hurricane Maria in the Fall of 2017, there was a complete lack of any government-run water quality monitoring. Operating out of a primary lab in Rincon and secondary lab at the Ramey School in Aguadilla, the Rincon Chapter has banded together with local groups and organizations to restart their water testing program. All Blue Water Task Force results are posted to the Blue Water Task Force website, posted to community boards, broadcasted on radio stations, and shared on Facebook.

Blue Water Task Force results are compared to water quality criteria established by the EPA to protect public health in recreational waters. Test results are expressed as the Most Probable Number (MPN) of enterococcus cfu (colony forming units) per 100 mL seawater by using the IDEXX Quanti-Tray/2000 MPN Table.When a site is marked Green, it indicates low bacteria (between 0 and 104 MPN/100 mL). When marked Red, results showed high bacteria (above 104 MPN/100 mL).All data can be viewed at go.surfrider.org/BWTF.
