Ecuador Shuts Down Mining in Three Provinces After Toxic Metals Found in Rivers

The government found poison in the rivers — and shut the mines down.

What Happened

On February 2, 2026, Ecuador's Environment Minister Ines Manzano announced an indefinite suspension of all mining operations in Napo province and restrictions on approximately 80 gold processing plants in El Oro and Loja provinces.

The action came after government water testing conducted on January 14 found dangerous concentrations of heavy metals in the Calera and Amarillo rivers:

| Substance | Found | Safe Limit | |-----------|-------|------------| | Cyanide | Detected above limits | Trace amounts | | Arsenic | Elevated | 10 µg/L | | Copper | Elevated | 2 mg/L | | Lead | Elevated | 10 µg/L | | Cadmium | Elevated | 3 µg/L |

All five substances exceeded WHO and Ecuadorian safe limits for surface water.

The Scale of Destruction

Government satellite imagery and ground surveys revealed the extent of illegal mining damage:

• 1,700 hectares of forest destroyed in affected mining zones
• River systems contaminated with mining runoff across three provinces
• Artisanal and small-scale operations operating without environmental permits or water treatment
• Gold processing plants using mercury and cyanide leaching methods that discharge directly into waterways

The Organized Crime Connection

Minister Manzano explicitly linked the mining crisis to organized crime. Illegal mining operations in Ecuador have increasingly come under the control of narco-trafficking organizations that use gold mining as a money laundering vehicle and a revenue stream.

The government's crackdown is part of a broader strategy that includes:

• Military deployments to mining zones in Napo and El Oro
• Seizure of mining equipment — heavy machinery, chemical supplies, and transport vehicles
• Confiscation of extracted minerals, which will be transferred to state mining company ENAMI (Empresa Nacional Minera)
• Criminal referrals to the Fiscalía (Public Prosecutor) for environmental crimes and money laundering

Affected Regions

Napo province (Amazon region): All mining suspended indefinitely. The province is home to critical Amazon watershed tributaries that feed into the Napo River system — one of the major tributaries of the Amazon River itself.

El Oro province (southern coast): Approximately 60 gold processing plants affected. El Oro has been Ecuador's traditional gold mining heartland, with the Portovelo-Zaruma mining district operating since colonial times. The distinction between legal and illegal operations has blurred as organized crime penetrates the sector.

Loja province (southern highlands): Approximately 20 processing plants restricted. Mining activity has expanded rapidly in recent years, often into areas with minimal environmental oversight.

What This Means for Expats

• Water quality is a direct concern. Expats in Vilcabamba (Loja province) and other southern highland communities should be aware that river contamination can affect municipal water supplies. Consider water testing if your home draws from well or river sources
• This affects Vilcabamba specifically. Loja province mining restrictions are partly in watersheds that feed the Vilcabamba valley — one of Ecuador's most popular expat retirement destinations
• El Oro mining communities may see economic disruption. If you have property or business interests near Zaruma, Portovelo, or Piñas, expect increased military presence and potential access restrictions
• The narco-mining connection is the bigger story. Illegal mining has become one of Ecuador's most visible organized crime activities. The government's willingness to shut down entire provinces signals a serious enforcement escalation
• Seized minerals going to ENAMI means the state is asserting control over the extractive sector — a policy direction with long-term implications for foreign mining investment
