Yucatán: Water Quality - Groundwater
2002: national water quality monitoring network was redesigned: Primary network = 362 permanent stations: 205 surface, 44
coastal, 113 aquifers. Secondary network = 276 mobile stations: 231 surface, 17 coastal,
and 28 aquifers. Reference Network = 104 additional stations explicitly for
groundwater. Aquifers in Quintana Roo Dept. and Yucatan State: not
overexploited, no significant salt-water intrusion, soil salinization or brackish groundwater

Biochemical Oxygen Demand (BOD): 100% of Yucatan peninsula stations show “unpolluted” with BOD
less than 6mg/L (typical of natural waters) Chemical Oxygen Demand (COD):
86.6% of Yucatan stations show unpolluted COD (less than 20 mg/L, typical of natural waters)
6.7% show “good quality” (20mg/L<X<100mg/L, water with organic matter)
6.7% show “Indications of pollution” (100mg/L<X<250mg/L, presence of wastewater, mostly urban)

Findings & Stresses: Sufficient water quantity
to meet needs Summary of water
quality: presently there are minimal water quality problems
Potential exists for future water quality problem from point and non-point source threats
Climate change?
