there is no discharge to the surface waters, nor any contravention of groundwater or surface water
standards. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions or failure of the high -rate infiltration area to adequately assimilate the
wastewater, the Permittee shall take immediate corrective actions including those actions that may be
required by the Division, such as the construction of additional or replacement wastewater treatment

1. 3 x year monitoring shall be conducted in March, July, and November; Annual monitoring shall be conducted every November.
2. The measurement of water levels shall be made prior to purging the wells- The depth to water in each well shall be measured from
the surveyed point on the top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining
parameters
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring
point for each monitoring well. The measuring points (top of casing) Of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the fallowing methods:
(A) Standard Method 6230D, PQL at 0.5 ug/L or less
(B) Standard Method 621 OD, PQL at 0.5 ug/L or less
(C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
(D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
(E) Another method with prior approval by the Aquifer Protection Section Chief.
Any method used must meet the following qualifications: (1) A laboratory must be DWQ certified to run any method used; (2) The method
used must, at a minimum, include all of the constituents listed in Table VIII of Standard Methods 6230D; (3) The method used must
provide a PQL of 0-5 ug/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory
Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 ug/L must be qualified (estimated) and reported.
