Pollution threatens the Sosúa River, despite being a key source of water since 1948

SOSÚA, PUERTO PLATA. — The Sosúa River, one of the most important tributaries in the northern region and a historic source of water for the municipalities of Sosúa and Puerto Plata since 1948, is currently facing severe environmental degradation that threatens its health and that of the nearby coastline.

The river originates on the northern slope of the Cordillera Septentrional mountain range, specifically on the Bella Vista hill, in the Arroyo Seco area, and on the slopes of the Cerro de la Colorada hill. Barely 6 kilometers long, its flow has traditionally been sufficient to supply drinking water to thousands of families in both municipalities.

However, despite its strategic value, the tributary has been ignored and unprotected for decades. Currently, the authorities in charge of water distribution close the valves in Sosúa to prioritize water supply to Puerto Plata, a practice that has been ongoing for years.

The deterioration begins just 1 kilometer from the mouth

Although its source remains free of pollution, the problem starts just one kilometer before it reaches the sea, where the river starts to receive human waste, altering its quality.

Among the sources of pollution identified are:

• Houses built within the 30-meter environmental protection zone

• Mechanics’ and paint shops that discharge waste

• Pigsties and animal husbandry

• Washing clothes directly in the riverbed

• Monoculture farming and pesticide runoff

• Streams that flow into the river

• Waste left by bathers in the spring area

After passing the treatment plant, two springs sustain the river’s flow and are frequented by residents who bathe, leaving trash on the banks. From that point to its mouth, the river is highly polluted.

Impact on the sea and the coastline

Ocean currents carry sediment and waste from La Piedra in Los Charamicos to the beaches of Puerto Plata and Maimón, affecting water quality and coastal ecosystems.

Experts warn that the lack of environmental controls is causing cumulative effects that affect not only marine life but also tourism, fishing, and public health in the area.

Authorities without an action plan

Despite the magnitude of the damage, the Sosúa City Council does not have a formal solid waste collection and management program aimed at preventing river pollution, according to technical references based on field data from architect Francis Santana M. (1997).

Environmentalists insist that the rescue of the Sosúa River requires political will, enforcement of regulations, relocation of homes in vulnerable areas, and ongoing community education campaigns.
