Water Quality Profiler
CURRENT STATE, SCOPE OF WORK, AND SPECIAL CONSIDERATIONS
B.1 CURRENT STATE:
Thornton is a home-rule city in Adams County, Colorado, located ten (10) miles northeast of
Denver. Thornton utilizes surface sources for its drinking water for its over 200,000 residents
and customers. The reservoirs of interest for this project have frequent water quality issues
that arise due to the stratification of the water body and subsequent internal loading. Presently,
Thornton measures three (3) depths once a week in these reservoirs, which is insufficient for
our needs. To better understand and monitor changing water quality parameters, Thornton is
seeking a water quality profiler(s) to measure parameters at depth.
B.2 SCOPE OF WORK:
Thornton intends to purchase one (1) or potentially up to two (2) water quality profilers. The
priority reservoir for this project is East Gravel Lakes Reservoir #4 (hereafter, “EGL #4”), which
is located to the southwest of the intersection of E 88th Avenue and Dahlia Street in Thornton.
The second, optional reservoir for this project is West Gravel Lakes Reservoir #2 (hereafter,
“WGL #2”), which is located across the South Platte River from and west of EGL #4, and south
of the intersection of E 88th Avenue and Colorado Boulevard in Thornton. See Figure 1 below.
Figure 1. Location of WGL #2 and EGL #4.
