Samples were collected by SAIC-Benham and were analyzed by Lancaster Laboratories,Inc. TDS were analyzed using EPA Method 160.1,sulfate using EPA Method 300.0, chloride using EPA Method 300.0, <br /> nitrate(as nitrogen)using EPA Method 300.0,nitrite(as nitrogen)using EPA 300.0,specific conductance using EPA 120.1,Kjeldahl nitrogen using EPA 351.2,phosphate using EPA 365.1,ammonia(as nitrogen) <br /> using 350.2,alkalinity(as CaCO3)using SM 20 2320B,bicarbonate(as CaCO3)using SM 20 2320B,carbonate(as CaCO3)using SM 20 2320B,and hardness(as CaCO3)using SM 20 2320B. <br /> 2. Results in bold exceed WQOs and/or MCLS. <br /> 4. WQO(Tastes and Odors)that prohibits adverse tastes and odors or nuisance conditions. <br /> 5. WQO Suggested No Adverse Response Level. <br /> 6. WQO Agricultural. <br /> Sources: <br /> MCLS from EPA(June 2003)and CDPH(June 2010). <br /> WQOs defined in the Central Valley RWQCB Water Quality Control Plan(Basin Plan)for the Sacramento River Basin and San Joaquin River Basin(Fourth Edition),October 2007. <br /> WQOs may be stated in either numerical or narrative form.
