TABLE 1 <br /> QUALITY OF FACILITY SUPPLY WATER FROM 2 WELLS BLENDED <br /> AND WASTEWATER AS SAMPLED AT STANDPIPE <br /> Concentration or Value Supply Effluent <br /> of Constituent Wells 2 ' Discharged` <br /> Bicarbonate (HCO,) , mg/l 114. N/A <br /> Chloride (Cl ) , mg/l 5.6 ' 183.8 <br /> Sulfate (SOS) , mg/l 7.8 37.7 <br /> TKN (as N) , mg/l N/A 33.d <br /> Nitrate (N0,) , mg/l 4.8 2.5 <br /> Total Phosphorus (as P) , mg/l N/A N/A <br /> Calcium (Ca) , mg/1 17. 69.3 <br /> Magnesium (Mg) , mg/l 10.6 16. <br /> Potassium (K) , mg/l 7.4 <br /> Sodium (Na) , mg/l 11.3 50. <br /> Specific Conductance (EC) , umho/cm 260. 1203. <br /> pH (laboratory) , Std. Units 7.9 5.1 <br /> 5 day BOD, mg/l N/A 1114. <br /> Suspended Solids, mg/1 N/A 540. <br /> Total Dissolved Solids, mg/l 118.° 1565.e <br /> Ammonia Nitrogen (as N) , mg/l N/A N/A <br /> Sampled from blend tank of two wells by Calif. Water Lab, 6/30/88. <br /> Sampled from blend tank of two wells by Calif. Water Lab, 12/11/86. <br /> C QAP Technical Report & Operating Plan, 9/88. Data for tomato season. <br /> Reference 2 (see appendix) . <br /> Test results probably influenced by high organic content. Fixed dissolved <br /> solids is estimated at 800 mg/l . <br /> B. CB QU-" <br /> Load [t9s :at <br /> Order 88-094 limits the daily BODS loading to 75 lb/ac/day. Using this, it is <br /> calculated that a minimum of 214 acres will be needed with a daily wastewater <br /> discharge of 1 .5 million gallons (7000 gallons/ac/day at a level of 1286 <br /> mg/L) . Ample land to meet this requirement will be available with the <br /> addition of the 10 parcels for the 1990 season, Figure 1 . <br /> C. Hydraulic Loading Rates <br /> An irrigation water balance for pasture grasses during June through mid- <br /> October is presented in Table 2. In September, it is conservatively estimated <br /> that 246 acres will be needed for land app --ation without generating exces- <br /> sively saturated conditions. During perio::_' laving high evapotranspiration <br /> rates, such as July, substantial amounts o' eater from sources such as wells <br /> will be used to supplement (and dilute) the wastewater. Plant washwater from <br /> sauce—making operations during November - May will be applied to a minimum of <br /> 4 <br /> RP050-L <br />
