Leachate Collection System Inspection Checklist [FREE PDF]

Leachate collection and removal systems (LCRS) at municipal solid waste landfills are subject to strict design, operational, and monitoring requirements under EPA RCRA 40 CFR 258 Subtitle D and corresponding state solid waste regulations. Failure to maintain adequate leachate collection performance can result in groundwater contamination, liner system damage, and significant regulatory enforcement actions. This inspection checklist enables landfill operators to systematically verify LCRS integri

  • Industry: Landfill Operations
  • Frequency: Monthly
  • Estimated Time: 45-60 minutes
  • Role: Landfill Operator
  • Total Items: 38
  • Compliance: EPA RCRA 40 CFR 258.40 - Design Criteria for MSWLF, EPA RCRA 40 CFR 258.51 - Leachate Collection and Removal Systems, EPA RCRA 40 CFR 258.55 - Groundwater Monitoring Requirements, EPA Clean Air Act 40 CFR 60 Subpart WWW - MSW Landfill Emissions, State Solid Waste Regulations - Leachate Management Plan Requirements

Leachate Head Level Monitoring

Measure and record leachate head levels in collection sumps and monitoring points to ensure compliance with maximum allowable head standards.

  • Is the leachate head level in all primary collection sumps at or below the 30-cm regulatory maximum?
  • What is the current leachate head measurement at the primary sump (cm)?
  • Have leachate head levels been recorded in the operations log with date, time, and measuring personnel noted?
  • Are leachate head level trends being tracked over time to identify potential system performance degradation?
  • Have any head level exceedances occurred since the last inspection and been reported to the regulatory authority?

Sump & Pump System Inspection

Inspect all leachate collection sumps and submersible or riser-mounted pumps for operational status, wear, and adequate performance.

  • Are all leachate collection pumps operational and confirmed cycling on inspection date?
  • Are pump run-time hours and cycle counts logged and within expected operating parameters?
  • Is pump intake screening free from clogging by sediment, fine particles, or biological fouling?
  • Are pump discharge pressure readings within the manufacturer's specified operating range?
  • Are backup pumps or standby pump systems available and tested within the past 90 days?
  • Are sump access risers, covers, and seals in good condition with no evidence of damage or unauthorized access?

Conveyance Piping & Header System

Inspect leachate collection lateral pipes, header pipes, and cleanout ports for physical integrity, flow, and blockage indicators.

  • Are all visible leachate collection pipe cleanout ports accessible and properly capped or sealed?
  • Has a CCTV or pipe camera inspection of collection laterals been conducted within the past 12 months?
  • Is there any evidence of surface seepage, leachate breakouts, or discolored soil adjacent to collection pipe routes?
  • Are header pipe joints, connectors, and valves free from visible leakage or corrosion?
  • Are flow meters or totalizers on conveyance lines functional and recording accurate cumulative leachate volumes?

Leachate Storage & On-Site Treatment

Inspect leachate storage tanks, ponds, or lagoons and any on-site pre-treatment systems for capacity, integrity, and regulatory compliance.

  • Are leachate storage tanks or impoundments at or below their design operational capacity limits?
  • Is the current leachate storage volume recorded and within permitted maximum storage levels?
  • Are storage tanks or lined impoundments free from visible cracks, seam separation, or evidence of liner compromise?
  • Are leachate storage areas equipped with functioning level alarms set below overflow elevations?
  • Is any on-site leachate pre-treatment system operating within permitted effluent parameter ranges?
  • Are leachate characterization samples collected and submitted to a certified lab per the approved monitoring schedule?

Liner System Visual Assessment

Conduct a visual survey of accessible liner system areas, anchor trenches, and perimeter berms for signs of physical damage or settlement.

  • Are exposed liner panels or geomembrane sections free from tears, punctures, wrinkles, or UV degradation?
  • Are anchor trench perimeters and liner termination zones intact and free from erosion or undermining?
  • Is there any evidence of differential settlement or subsidence in waste mass areas that could stress the liner system?
  • Are perimeter berms and dike structures free from erosion, animal burrowing, or vegetative root intrusion?
  • Has a photo record of liner system conditions been captured and filed with today's inspection report?

Groundwater Monitoring Program Coordination

Verify that groundwater monitoring wells associated with the LCRS are properly maintained, sampled on schedule, and results reviewed for statistical exceedances.

  • Are all required groundwater monitoring wells in the detection monitoring program intact, accessible, and properly secured?
  • Are groundwater sampling events completed on the regulatory schedule defined in the facility permit?
  • Have the most recent groundwater analytical results been reviewed and found to be below groundwater protection standards?
  • Are monitoring well casings, protective covers, and locking caps in good condition with no damage or vandalism noted?
  • Is a licensed geologist or hydrogeologist reviewing and certifying groundwater monitoring data reports?

Recordkeeping & Regulatory Reporting

Confirm that all LCRS operational data, inspection records, and regulatory reports are properly maintained and submitted on schedule.

  • Are daily and monthly LCRS operational logs (pump hours, leachate volumes, head readings) current and complete?
  • Have required leachate disposal or hauling manifests been filed and retained for the current calendar year?
  • Have all required regulatory reports (annual reports, groundwater monitoring reports) been submitted on schedule?
  • Are copies of the current facility permit, approved Leachate Management Plan, and CQA documents maintained on-site?
  • Are any open regulatory notices, compliance schedules, or corrective action orders being actively tracked and addressed?
  • Please document any deficiencies, corrective actions initiated, or follow-up items identified during this inspection?
