Quality Assurance <br />Two duplicate samples were collected during 1988 for laboratory quality <br />assurance purposes. One of the duplicate samples was taken at surface water <br />monitoring station TR-C in July while the other was taken at ground water <br />monitoring well TR-4 in August (sample dates in the appendix with an <br />indicate duplicate samples). Results of the duplicate analyses were not <br />favorable for all parameters tested. The duplicate sample taken at TR-C showed <br />four of five parameters to be within ± 54 of the original values obtained. <br />However, the duplicate sample taken at TR-4 showed only four of nine <br />parameters to be within t 59 of the original values obtained. <br />VII. Spring and Seep Survey <br />A survey was conducted in early July, 1988 to located springs and seeps <br />which may be developing at the base of the ridge along Trout Creek from NPDES <br />discharge point No.003 northward to the base of West Ridge. A total of 3 <br />springs and 2 seeps were located as a result of the survey (see enclosed map). <br />Only one spring had sufficient flow to be of interest. That spring is <br />currently monitored on a regular basis and is designated as NPDES discharge <br />point No. 006. All of the springs and seeps located during 1988 have been <br />noticed in previous years. Through discussions with the Colorado Mined Land <br />Reclamation Division is was determined that the spring and seep survey should <br />be performed earlier in the year in an attempt to locate springs and seeps <br />which may be of shorter duration during the late spring runoff period. As a <br />result of those discussions, the permit has been revised to indicate that <br />future surveys will be performed in May of each year. <br /> <br />
