Parts of the beach have lost their former status as a Blue Flag beach due to an increase in fecal matter that can now be found in the water. For the most part, this affects the main beach area while the far end, toward the fishing boats, still meets Blue Flag requirements.
Please also note that the water along the ENTIRE beach area is still considered SAFE for swimming...
Here is an excerpt from a report by Voice of Guanacaste:
"Although South Samara Beach, from Mala Noche River to Sangrado Estuary, continues to earn the Ecological Blue Flag, the main stretch of Samara Beach from Mala Noche River to Cangrejal lost the coveted flag this year by five points because of water contamination, and now that the test results from AyA are available, the Pali supermarket is suspected as a source of the contamination.
The microbiological quality of the ocean water accounts for 35% of the score to earn the blue flag, with points awarded based on the level of fecal material found."
"Five points along the beach were tested in all by AyA on February 20, 2014, according to the report. The results found no traces of fecal coliforms in front of La Bahia bar and restaurant, trace levels (7.3 per 100mL) in front of the post office and 200 meters to the right of the estuary near the rocks, and a reading of 23 in front of Cabinas Playa Samara.
These levels are still considered safe for swimming, although non-chlorinated water with the presence of 1.8 coliforms or above per 100mL is considered unsafe for drinking, according to the water microbiology lab of the University of Costa Rica (UCR)."
