<br /> Notes:
<br /> 1. Samples were collected by SAIC and analyzed by Lancaster Laboratories,Inc.
<br /> Chloride was analyzed using EPA Method 300.0,nitrate(as nitrogen)using EPA Method 300.0,nitrite(as nitrogen)using EPA 300.0,
<br /> specific conductance using EPA 120.1, Kjeldahl nitrogen using EPA 351.2,phosphate using EPA 365.1,ammonia(as nitrogen)using 350.2,
<br /> alkalinity(as CaCO3)using SM 20 2320B, bicarbonate(as CaCO3)using SM 20 2320B,carbonate(as CaCO3)using SM 20 2320B,
<br /> and hardness(as CaCO3)using SM 20 2320B.
<br /> 2. Results presented in bold exceed WQOs and/or MCLS.
<br /> 3. WQO(Chemical Constituents)which requires compliance with California drinking water MCLS and generally prohibits adverse effects on beneficial uses.
<br /> 4. WQO(Toxicity)that prohibits toxic chemicals in toxic amounts.
<br /> 5. WQO(Tastes and Odors)that prohibits adverse tastes and odors or nuisance conditions.
<br /> 6. WQO Suggested No Adverse Response Level
<br /> 7. WQO Agricultural
