The growing amount of research in heritage languages (HL) consistently suggests that HL learners are a diverse population with language abilities that span across the whole spectrum of the bilingual range (Valdés 2001). Receptive bilinguals, sometimes called passive bilinguals, are at one end of this bilingual range, almost at the verge of culminating the language shift towards English monolingualism. This population of HL students has received scant attention from HL programs and researchers alike. The present study fills this gap in the literature by focusing specifically on receptive bilinguals of different generations enrolled in Spanish classes at a large university in the southwestern United States. It seeks to provide insights into their cultural and linguistic profile so as to begin to understand the factors that have influenced their current Spanish use and linguistic abilities in the language.

Arizona, located in the arid Southwestern United States, is heavily dependent on groundwater. In order to protect this limited resource, wastewater reuse has been implemented. Virus and Giardia monitoring of wastewater used for irrigation has also been initiated as a means for controlling the public's exposure to these pathogens. Treatment facilities must produce wastewater with no detectable Giardia cysts and one virus plaque forming unit (pfu) per 40 liters (L) for unrestricted reuse. For restricted reuse, 125 pfu/40 L is allowed. Methods based on filtration were used to monitor facilities at monthly, quarterly or biannual frequencies. Results after two years of monitoring are presented. All 11 treatment facilities produced water meeting the virus standard of 125 pfu/40 L. Only plants which used sand filtration and disinfection achieved consistent levels of virus below 1 pfu/40 L. Out of 70 samples, 74% contained no detectable viruses. Giardia was detected in 29 to 50% of the samples. Most plants would need to upgrade their treatment in order to meet standards for unrestricted irrigation.
