-z- <br />' ~"~ <br />v <br />Boron was determined colorimetrically, Sulfate turbidimetrically, and <br />Chloride and Fluoride by specific ion electrode using the procedures of <br />EPA Methods for Chemical Analyses of Water and Wastes, 1979. Total Dissolved <br />• ~ Solids TDS) and Total Suspended Solids TSS~were determined gravimetrically <br />by the procedures of Standard 14ethods, 14th edition. TDS is also calculated <br />using the weights of constituents found in individual analyses. Alkalinity, <br />Bicarbonate, Carbonate and Hardness were determined titrimetrically according <br />to procedures of Standard Methods, 14th edition. Hardness was calculated from <br />the dissolved parameters and compared with the titrated values. Specific <br />Conductance and pH were determined by electrode response. Sodium Absorption <br />Ratio and Ion Balance were also calculated and compared against TDS and <br />Specific Conductance data. <br />The results of these analyses are presented in the tables and are reported in <br />milligrams per litre (mg/1) except pH or otherwise noted. (Regrettably, both <br />bottles for "P River below Alten Refuse" were filtered, so no analyses can be <br />reported on the total metals.) <br />_~ <br />~ ~~ 2,, r <br />Bruce A.
