has proven effective in reducing pollution from point sources
The most important point sources
are identified: B9, E501, B2, INT801, A3, B8, and G101.
This paper presents the full-energy peak efficiency calibration of a 40% p-type HPGe detector for point source
, Marinelli beaker, and cylindrical container geometries.
stormwater discharges from point sources

Under a TMDL, "Waste Load Allocations" are assigned to point sources
such as wastewater treatment plants, while "Load Allocations" are assigned to nonpoint sources such as agricultural runoff.
The point source
approximation method is described in Ref.
It should be pointed that if two or more point sources
are concentrated in a sufficient small domain, the proposed method in the following section will treat them as one point source
