Sampling to Characterize Stream Plumes
New perspectives are offered on taking samples to determine pollutant concentrations in a stream cross section. By combining plume simulation with a gradient search curve fitting procedure, a means is provided to characterize a pollutant plume by finding its mass flux, center of concentration, and lateral dispersion. Additionally, a number is determined of grab samples needed from the cross section of the plume to find these characteristics. As few as four grab samples from the cross section of a plume are sufficient. If the lateral position of a pollutant in a stream is not known, the negative binomial distribution offers some insight into determining how many grab samples to draw. A consideration of cost factors is included.
