A “bad” substance is believed to have been released from a Pemex facility in Mexico that already could have impacted Falcon Reservoir, and federal and state agencies are advising water rights holders along the Rio Grande, the Valley Morning Star learned.
The Texas Commission on Environmental Quality has issued a precautionary notification of the material release after the International Boundary and Water Commission noted that its counterpart in Mexico had alerted it to this. TCEQ also learned that there had been a fish kill around April 8 in Mexico about 90 miles upstream of the border.
“They do not know what the material is or the quantity released, but it went into the Rio Salado and is headed toward the Rio Grande near Zapata,” the precautionary notification states.
TCEQ noted that, “while we are not directing any (water) diverters to cease diverting at this time, we would encourage you to consider alternate sources of water if you have them available.”
