Acquisition and analysis of environmental data are essential to the quality, safety and health of human life, and typically consist of heterogeneous, multivariate, and spatio-temporal information collected from different resources. In the United States, the Environmental Protection Agency (EPA) is responsible for protecting human health and the environment; it does so by developing and enforcin...

The California Environmental Protection Agency (Cal/EPA) Environmental Justice Action Plan calls for guidelines for evaluating "cumulative impacts." As a first step toward such guidelines, a screening methodology for assessing cumulative impacts in communities was developed. The method, presented here, is based on the working definition of cumulative impacts adopted by Cal/EPA: "Cumulative impa...

Widespread contamination of groundwater by chlorinated ethenes and their biological dechlorination products necessitates the reliable monitoring of liquid matrices; current methods approved by the U.S. Environmental Protection Agency (EPA) require a minimum of 5 mL of sample volume and cannot simultaneously detect all transformative products. This paper reports on the simultaneous detection of ...

The U.S. Environmental Protection Agency (EPA) Endocrine Disruptor Screening Program (EDSP) currently relies on an initial screening battery (Tier 1) consisting of five in vitro and six in vivo assays to evaluate a chemical's potential to interact with the endocrine system. Chemical companies may request test waivers based on Other Scientifically Relevant Information (OSRI) that is functionally...

We evaluated the efficacy of different field sampling approaches for volunteers sampling macroinvertebrates in low-gradient streams. We used a series of analytical metrics to compare results using the Environmental Protection Agency (EPA) multihabitat, the Minnesota Pollution Control Agency multihabitat, and EPA single-habitat sampling protocols. We also investigated the effect of 2 scenarios i...

In a joint U.S. Environmental Protection Agency ( EPA) and DuPont waste minimization project, fifteen waste streams were selected for assessment. The intent was to develop assessments diverse in terms of process type, mode of operation, waste type, disposal needed, and relative success in identifying good waste reduction options. The fifteen case study reports describe the wastes and the proces...

A driving cycle is a record intended to reflect the regular use of given type vehicle, presented as speed profile recorded over certain period time. It used for assessment engine pollutant emissions, fuel consumption analysis and environmental certification procedures. Different cycles are used, depending on region world. In addition, drive by car manufacturers optimize vehicle drivelines. The ...
