The Town of Keenesburg is located in Weld County 30 miles north of Denver on I-76. The
population is 1100, and the Town currently serves about 461 water taps. The water supply comes
from 5 wells that draw water from the Laramie -Fox Hills aquifer, and have a total capacity of 221
acre-feet per year. They are connected directly to the Town's distribution system. There are two
major issues associated with the water system -water quality due to high fluorides and sodium,
and lack of disinfection contact time. The maximum contaminant level (MCL) for fluoride is 2 mg/I
and reported levels in the Town's water wells are 3.1 mg/I. The Laramie Fox-Hills water also has a
high Sodium Absorption Ratio (SAR), a ratio used to determine the suitability of the water for use in
the irrigation of landscaping. A ratio of less than 10 is suitable for irrigation, and the Town's water
has been recorded at a level of 26.9. The Town's well water is pumped directly into the distribution
system, which results in some users not receiving proper disinfection contact time. The Town has
undertaken a separate project that will allow well water to be pumped to the water storage tank prior
to being delivered to distribution. The proposed project with CWCB funds, includes purchase of
139.6 AF of well water rights in the Lost Creek Groundwater Basin, and construction of 5.5 miles of
pipeline to the Town. The purpose of the project is to improve the water quality by blending the
new water with the existing Laramie-Fox Hills water. Blending the water has been evaluated, and
providing a 50%-50% blend of the two waters shows that the SAR ratio drops below 10, and the
fluoride level drops to approximately 1.5 mg/I, below the MCL of 2 mg/I.
