Determine the relation between contaminant sources
in the area upstream from a community drinking-water intake and the
concentrations of these contaminants at the intake.
Compare the occurrence of contaminants in the raw
water supply with those found in the treated water supply.
One stream site will be sampled during the first
year. The site will represent a large percentage of the water used
for public water supply in a community in the South Platte River Basin.
Treated water from the community’s drinking-water treatment plant
will be sampled during the second year.
Sampling of the raw water will take place between
October 2002 and September 2003. Sampling of the treated water will
take place between October 2003 and September 2004.
