Attachment 1 includes weekly leachate tank samples collected since May 2022. The annual 2021 and 2022 leachate tank sampling reports. 4. Contractor shall analyze the data and make their own assumptions and projections of leachate quantity and quality to determine if their equipment will perform as anticipated. 5. The goal of the treatment system shall be to reduce the overall ammonia-N levels to less than 60 mg/L and Iron to less than 4 mg/L. 6. The ROPT shall operate for a minimum of 340 days per year. 7. Contractor shall dispose of industrial wastewater, and contaminated and/or hazardous materials and may price separately from the based ROPT operation and maintenance services. 8. Alternative concentrate removal methods from the ROPT will be considered if proposed by the Contractor and accepted by the County in writing.
