Notes:
RED=Resulting concentration falls outside of the Numeric Protection Limit(NPL). <=not detected at concentrations exceeding the laboratory method detection limit
BLUE=Rosner Statistical outlier mg/L=milligrams per liter
'Analyzed by EPA Method 200.7 or 200.8. pg/L=micrograms per liter
'Analyzed by EPA Method 200.8. pS/cm=micro Siemens per centimeter
'Analyzed using field instrumentation. EPA=Environmental Protection Agency
°Analyzed by EPA Method 300.0. (Blank Field)=No data was required for this parameter during monthly pH assessment monitoring
