Although the level of sampling is inadequate to judge the <br />statistical significance of apparent trends, it is adequate for <br />making comparisons and providing insight for future sampling <br />efforts. <br />The data obtained from lab analysis of water samples is <br />provided in Appendix C. It includes an analysis of conductivity, <br />pH, total suspended solids, alkalinity, nutrients, and metals <br />concentrations. <br />The results of the water chemistry analysis tend to indicate <br />that several changes take place after excavation of the peat. <br />The changes that were noted tended to occur consistently between <br />sites, with the exception of the Eureka site, where changes <br />occurred in the same constituents but generally with the opposite <br />sign. The parameters in which a change was noted are discussed <br />below for each of the four sites. <br />As a measure of the accuracy of the sampling and analysis <br />procedures a cation -anion balance was completed. As noted in <br />Standard Methods for the Examination of Water and Wastewater <br />(1980), the acceptable limits for the cation -anion balance are <br />determined from a consideration of the standard deviations for <br />routine chemical analysis. Applying that to the data for the <br />above sites it was noted that the balance was within the <br />acceptable limits for only one out of twelve samples. Possible <br />explanations for this are: 1) errors in the sampling, 2) errors <br />in the lab analysis, 3) presence of cations other than those <br />which were measured, and 4) presence of organic acids.
