Hydrogeology of a contaminated sole-source karst aquifer, Mérida, Yucatán, Mexico

The City of Merida, in the State of Yucatán, obtains its drinking water primarily from three well fields located in the periphery of the city. In addition, there are water supply wells within the city. Water from the public water supply contains lead, cadmium, chromium in excess of the Mexican Drinking Water Norm. The following organic contaminants have also been identified in the ground water ...

Determination of karst aquifer characteristics using physicochemical parameters (A case study from west of Iran)

The karstic Rijab Spring with an average discharge of 3290 l/s is located in the Alvand River basin in the northwest of the Zagros, Iran, which drains Asmari formation. To investigate groundwater flow in the catchment area of the Spring, the physicochemical parameters include major cations and anions, discharge, EC, pH, and temperature were studied from September 2000-2002. The results indicate...

Variation in Aedes aegypti larval indices over a one year period in a neighborhood of Mérida, Yucatán, México.

Surveys for Aedes aegypti larvae were conducted to provide an estimate of the magnitude and timing of seasonal variations in larval indices in one colonia in Mérida, Yucatán, México, and to assess how the proportion of disposable and non-disposable containers as larval production sites varies. Breteau indices exceeded 200 during the months of July and August, and disposable containers were impo...
