Toxic copper mine spill in Mexico prompts water restrictions

Grupo Mexico’s Buenavista del Cobre mine

Read this Aug 11 story from mining-technology.com on a toxic wastewater spill from a Mexican copper mine.

Mexican authorities have imposed restrictions on water supplies in some cities and towns in the northern part of the country, including the Sonora state capital of Hermosillo, following a spill of contaminated wastewater from the nearby copper mine.

Contaminated wastewater from Buenavista del Cobre, a copper mine owned by Grupo Mexico, reportedly spilled into the Bacanuchi River in north-west Mexico, killing fish and livestock.

The National Water Commission (Conagua) was quoted by InterAksyon.com as saying: “The mine spilled approximately 40,000m³ (1.4 million ft³) of leached copper into the Bacanuchi River, a tributary of the Sonora River.”

According to authorities, the toxic substance included sulphuric acid, which turned the river water into orange colour.

Following the leak, federal officials restricted the water supply to seven municipalities in the country’s north-west region. Other affected towns include Arizpe, Banamichi, San Felipe de Jesus, Aconchi, Baviacora and Ures.

The National Water Commission is monitoring chemicals in the Bacanuchi and Sonora rivers.

    This is a near parallel to the Mount Polley tailings dam failure … and the BC government says the water is ok to drink? … for sure, Eh! … Christy said so [wink-wink]
