Paper: Contamination may destroy Patzcuaro lake in 10 yrs.

Monday, December 15, 2003

The Patzcuaro lake in western Mexico's Michoacan state, may be rendered unusable in 10 years if contamination and deforestation continues, Reforma quoted national water commission (CNA) state director Roberto Valenzuela Castillo as saying.

An estimated 28,000 cu. m/d of wastewater is dumped in to the lake. The contamination, including pesticide runoff from local farms, has depleted fish stocks.

Local residents produce 135,000 t/y of solid waste, of which some is dumped into the lake, the paper added. The last CNA monitor reported a recovery of 68M cu. m. in the lake, while the total volume of accumulated water is 431M cu. m.

The state government signed in February an agreement with the environment ministry to recover the water basin for an initial 61mn pesos (US$5.4mn). Works would include two water treatment plants and other biological and water controls.
