  • Multiple antibiotic resistance indexing

    Knowledge of the source of drinking water contamination enables the development of suitable programs and strategies. An article in Water Science and Technology: Water Supply describes the use of multiple antibiotic resistance (MAR) indexing to classify sources of microbial contaminant. The provision of safe ...


  • Mold problems expected for many across Northeast US

    Record warm temperatures are blaketing the northeast this week replacing historical flooding from the past of storm of this past weekend.
