Cleanup crews tally record plastic haul as monsoon drains inland

The morning tide at Playa Blanca, south of Puerto Azul, leaves behind a line of plastic bottles, foam packaging, and tangled fishing line that stretches nearly two hundred metres. Rosa Hernández, who leads the Puerto Azul cleanup cooperative, walked the beach at dawn on Wednesday and counted more debris than in any August she could recall. The cooperative's daily tally from the past week has topped three tonnes of plastic per beach, compared to an average of one tonne in previous years.

The surge follows the heaviest monsoon rains in six years, which began in late July and have swollen Costa Mar's inland rivers and runoff channels. Nutrient loads in the water column have also spiked, according to readings from the Costa Mar Reef Monitoring Network's station at Punta Verde. The combination is flushing material from inland agricultural zones, urban drains, and river settlements directly to the coast.

The cleanup crews have responded by extending their routes and recruiting volunteer divers to clear debris from shallow reef zones where it snags on coral. The Marine Ministry in Puerto Azul has allocated additional funding to purchase collection equipment, though officials acknowledge the underlying problem lies upstream. The question now is whether the federal government will press inland municipalities to upgrade their waste-management systems before the next heavy rains arrive.
