Fork sites during the third sampling period) include laboratory analyses <br />of pH, conductivity, total dissolved solids (TDS), total suspended solids (f55), calcium, magnesium, sodium, SAR, hardness, bicarbonau, <br />chloride, nitrate/nitric, phosphate (PO,"' az P), sulfau, iron (total and dissolved), manganese (total and dissolved), aluminum (dissolved), arsenic <br />(total recoverable), cadmium, copper, lead, mercury (total recoverable), molybdenum, selenium (total recovereble), and zinc. All paramcers were <br />analyzed (or their dissolved form unless stated otherwise. <br />' If water is present, samples will be obtained three times per year for laboratory analysis of TDS, Fe (total and dissolved), Mn (total and <br />dissolved), and TSS. <br />" No Flow measurement. <br />' Underdrain flows to MB2-R are sampled scazonally.
