All analyses <br />must use detection limits at or below State Standards and/or <br />Minimum Criteria; <br />11.. Surface water elevations at sampling locations S-9, S-12, S- <br />13 and S-14 must be measured to the nearest 0.01 foot on the same <br />day as ground water levels in the wells and piezometers and <br />reported semiannually.unless required more frequently by permit <br />condition. All water level measurements must be made within a <br />one day period. These measurements must be referenced to NGVD. <br />LEACHATE QUALITY MONITORING <br />12. The site designated for leachate quality testing is L-1. <br />The site is listed on Attachment A and shown on Attachment B. <br />13. Samples from the leachate monitoring site shall be analyzed <br />as follows: <br />SEMI-ANNUAL ANALYSIS - pH (field), specific conductance (field), <br />temperature (field), dissolved oxygen (field), bicarbonate as <br />HCO3, chlorides, iron, mercury, nitrate as N, total ammonia as N, <br />total dissolved solids and the EPA 40 CFR, Part 258, Appendix I <br />parameters. All analyses must use detection limits at or below <br />State Standards and/or Minimum Criteria; <br />ANNUALLY - In addition to the semi-annual analyses, the EPA 40 <br />CFR, Part 258, Appendix II parameters. <br />MONITORING WELL REQUIREMENTS <br />14. If a monitoring well becomes damaged or inoperable, the <br />Permittee shall notify the Department in writing within seven (7) <br />days. The written report shall describe what problem has <br />occurred and the remedial measures that have been taken to <br />prevent a recurrence. The Department can require the replacement• <br />of inoperable monitoring wells. <br />15. New or replacement monitoring well design or placement must <br />be approved by the Department. Proposed well construction <br />details based on site specific borings must be submitted with all <br />supporting data (grain size analyses, in-situ hydraulic <br />conductivity testing, depth to water, etc.) for Department <br />approval prior to well installation.
