<br />The above data show that the salinity in 1992 was lower than
<br />of the water customarily delivered on the land boundary,
<br />averaged about 1,540 ppm for the 10-year period 1963-1972.

<br />The Yuma Desalting Plant was essentially completed and operated at
<br />one-third of capacity in 1992. The monthly 1992 discharge to the

<br />Point 5 of Minute No. 242 provides that:
<br />
<br />"Pending the conclusion by the Governments of the
<br />United States and Mexico of a comprehensive agree-
<br />ment on groundwater in border areas, each country
<br />shall limit pumping of groundwater in its territory
<br />within eight kilometers (five miles) of the Arizo-
<br />na-Sonora Boundary near San Luis to 197,358,000
<br />cubic meters (160,000 acre-feet) annually."
<br />
<br />In 1992, Mexico's pumping from its San Luis Mesa well field within
<br />eight kilometers (five miles) of the boundary near San Luis amount-
<br />ed to 81,374,000 cubic meters (65,971 acre-feet). The fOllowing
<br />quantities were pumped in calendar years 1975 through 1992.
