Book excerpt: "The Chilco channel aquifer, a peripheral aquifer contributing to the Rathdrum Prairie aquifer in northeastern Kootenai County, Idaho, was not designated a part of the sole source aquifer by the Environmental Protection Agency in 1978. Shallow water tables, varying from 35 to 230 feet (11 to 70 meters) below ground surface, coupled with moderate to highly permeable sediments similar to those of the Rathdrum Prairie aquifer, suggests that the area requires careful investigation and protection. Thirty one wells were sounded as part of this study during Summer, 1993 to determine the extent of the aquifer and depth to ground water. Water was sampled for nitrate, chloride, iron, phosphorus, hardness, alkalinity, specific conductance, and fecal coliform. Previous studies by Hammond (1974) and Painter (1991a) suggested that a saturated alluvial aquifer exists from Farragut State Park southwest to Garwood. Well logs indicate large subsurface channels within the subsurface draining generally east to west, that are presumably extensions of pre-Pleistocene drainage systems. The channels are partially to completely filled with glaciogenic sediments that are locally saturated. A deep channel within Eightmile Prairie bisects the originally defined aquifer, and a ground water divide exists at the north end of the Chilco channel. Based upon the presence of this ground water divide, the area was subdivided into two principle watersheds; the Sage-Lewellen watershed, a highland in the northeastern portion of the study area drained by Sage Creek and Lewellen Creek, and the Chilco channel watershed, south of the ground water divide. The ground water flow within the main Chilco channel comes primarily from recharge off the west slopes of the Coeur d'Alene Mountains and infiltration from precipitation. The water table is 35 ft (11 m) below the ground surface at the north end of the main channel and 230 ft (70 m) near Garwood. The hydraulic gradient is 0.004 in the northern portion of the channel, and 0.04 north of Garwood. Gromtd water flow from the main channel to the Rathdrum Prairie aquifer is 2 to 4 cfs (56.6 to 113.21/s). Hydraulic conductivity values for glaciogenic sediments found in the Chilco channel range from 30 to 75ft/day (98 to 246m/day) for coarse sediments and 3 to 9ft/day (9.8 to 88.2 m/day) for finer grained sediments. Ground water quality was found to be excellent within the Sage-Lewellen watershed, although fecal coliform was found in one well. Mean values for the measured water quality parameters were lower than comparable mean values from the Rathdrum Prairie aquifer. Shallow water tables in sand and gravel where Sage Creek and Lewellen Creek become influent could be susceptible to contamination and should be considered a recharge area. Ground water quality within the Chilco channel is good but mean values of hardness, alkalinity, and specific conductance were higher than comparable mean values for the same parameters in the Rathdrum Prairie aquifer, and they increased downgradient. The presence of fecal coliform and lower than average hardness, alkalinity, and specific conductance from a well near a site where water from Chilco Lake becomes influent to the aquifer suggests that contamination could occur from the lake. Since this implies the lake is a significant source of recharge for the aquifer, it should be protected in terms of its recharge contribution as well as its potential to contaminate the aquifer. Due to the similarity of hydrogeologic properties the Chilco channel alluvial aquifer shares with the Rathdrum Prairie aquifer, it is highly recommended that it receive the same level of protection as the Rathdrum Prairie aquifer. A wellhead protection program should be considered for the area."--Document.
