Description:

Abstract:

Rings (buffers) show the distance to the well and the time of travel (TOT) for contamination to reach the well head. The shallow alluvial aquifer from which Tecate's wells draw is characterized as fractured rock by the University of Utah. The buffer distances correspond to the minimum recommended distance for fractured rock aquifers by the California Drinking Water Source Assessment and Protection Program (Jan 1999). * Sinopsis: Anillos (buffers o zonas amortiguadoras) muestran la distancia al pozo y el tiempo de viaje (TOT) para que la contaminación alcance la boca de los pozos. El acuífero aluvial superficial del cual se alimentan los pozos de Tecate está caracterizado por la Universidad de UTA como de roca fracturada. La distancia de estos anillos corresponde a la mínima distancia recomendada para acuíferos de roca fracturada por el Programa de Evaluación y Protección de Fuentes de Agua Potable de California (enero 1999).

Purpose:

To show the time that it takes for a point source of contamination to travel through the fractured rock to the wellhead. Point sources within the 2 year ring are of special concern. * Propósito: Mostrar el tiempo que tarda la contaminación puntual en alcanzar la boca de pozo a través de roca fracturada. Fuentes puntuales que caen dentro del anillo en 2 años son de especial preocupación.

Supplemental_Information:

Buffer distances were calculated as 1.5R2, or a minimum of 900 ft for a 2 year time of travel (TOT). The second ring is 1,500 ft for a 5 year TOT. The outer ring is 2,250 ft from the well for a 10 year TOT. * Información Suplementaria: Las distancias de los anillos buffer fueron calculadas como 1.5R2, o un mínimo de 275 m (900 ft) para un tiempo de viaje (TOT) de 2 años. La distancia del segundo anillo es de 457.2 m (1500 ft) para un TOT de 5 años. El anillo exterior se encuentra a 686 m (2250 ft) del pozo para un TOT de 10 años.

Use_Constraints:

Not for use for drilling. While this data have been collected for use in spatial analysis and decision making, and for use in Geographic Information Systems, San Diego State Univeristy cannot guarantee the accuracy of the data. As with any spatial data, issues of scale, taxonomic classification, resolution, and precision will affect the perceived accuracy of the data. Users are ultimately responsbile for the appropriate application of and use of this data. * Limitaciones de Uso: No use para perforar. Mientras que estos datos se han compilado para su uso en análisis espacial y toma de decisiones, así como para su uso en sistemas de información geográficos, la universidad técnica CalPoly en Pomona y la Universidad Estatal de San Diego no pueden garantizar la exactitud de los datos. Como con cualquier dato espacial, las consideraciones de escala, clasificación taxonómica, resolución y precisión afectan la exactitud percibida de los datos. Los usuarios, en última instancia, son responsables del uso y aplicación apropiados de estos datos.
