Sentence examples for source contaminants from inspiring English sources

Remediation of streams impacted by non-point source contaminants requires an understanding of both the areas within a watershed that are contributing contamination to streams and the pathways of contaminant migration to streams.

The geographical information system (GIS) software is increasingly used in environmental studies because of its capability to expose non-point source contaminants (Sultan 2007; Wang et al. 2006) and as a visual support in interpreting heavy metal spatial distribution.

In situ standard toxicity assessment in various aquatic organisms has been used extensively in river environments to assess water and sediment toxicity, and this method is recognized as a useful tool for assessing non-point source contaminants ([Chappie and Burton 1997, Tucker and Burton 1999]).

Five sites along the Cache la Poudre River were monitored for antibiotics encompassing pristine areas without anthropogenic influence, urban areas impacted by wastewater discharges and agricultural areas susceptible to non-point source contaminant runoff.

The age distribution can be used to understand the intrinsic susceptibility of a well or the response of a well to a nonpoint source contaminant whose history may be anthropogenic in origin rather than natural.

Trends in concentrations of nonpoint-source contaminants in wells, springs, and streams are related to the history of contamination in groundwater recharge and the age distribution in the groundwater discharge.

The webtool also illustrates spatial relations between wells and their contributing recharge areas, which are important considerations for point-source and nonpoint-source contaminants.

In summary, relevance fields of studies can be benefitted from point-source contaminant research advances.

Einarson and MacKay (2001) demonstrate how point-source contaminant releases of varying magnitude can affect supply wells operating at different extraction rates, and state, "We do not advocate reliance on in-well blending to maintain water supply standards but ….

For assessment purposes, the vadose zone contamination was assumed to act as the only source of contaminants.
