Dissolved Sodium and <br />Potassium were analyzed by flame emission. Total Selenium (on both the <br />preserved and non-?reserved portions) was determined by hydride generation <br />atomic absorption. All samples to be analyzed for total metals were first <br />subjected to a rigorous digestion in nitric and hydrochloric acids. <br />boron was determined coloriinetrically; Sulfate turbidimetrically and <br />Chloride and Fluoride by specific ion electrode using the procedures of EPA <br />Methods for Chemical Anal ses of [dater and `dastes, 1979. Dissolved Solids <br />TDS and Suspended Solids TSB and Oil and Grease were determined <br />gravimetrically by the procedures of Standard Plethods, 14th edition. <br />pH, Carbonate, Bicarbonate, Alkalinity, Hardness and Specific Conductance <br />were all done by Standard t4ethods procedures. In addition, Hardness was <br />calculated from the dissolved contributing species (Ca, h1g, hln, etc.) and <br />compared against the titrated value. Sodium absorption ratio and Ion balance <br />were also calculated and compared against TOS and Specific Conductance data. <br />The results of these analyses are presented in the tables below and are <br />reported in milligrams per litre (mg/1) except pH or as otherwise noted. <br />S <br />is - - :'" <br />.::~~~ <br />uu~YCS .. . ue,..ec.. •.• •.. <n•ncusa. « . cu aawune +, • cuvu•.o.o.. asavte, co ~ cosow ca •..e.o uso. •• •+•sru. a ..moceseo+o .• <br />•.oeiu u • n,« eer.ce.u.. r• . xe« oncs•s ... «oerosa v. ..•u s•ot. co • •~a v~ue. a+. s•c~•• ~r . so ~au•«o. ~c ~ roct oa o• • vsww u. e e n+ <br />
