SCOPE OF SERVICES
PROFESSIONAL GROUNDWATER WELL SAMPLING, AND LABORATORY ANALYTICAL
SERVICES FOR THE NORTH PLEASANT VALLEY DESALTER
Provide transducer procurement and installation, groundwater well sampling, and laboratory analytical services related to the North Pleasant Valley Desalte r Project. Description of the Project tasks are provided below:
Task 1 – Project Management
Consultant shall include one (1) Kick -off meeting by conference call and progress updates after each sampling event by phone and/or email. The selected Consultant shall coordinate with the City to access wells, coordinate traffic safety, and provide a schedule for each sampling event.
Deliverables:
1) Pre-sampling event communication and schedule by phone and/or email.
2) Post-sampling event status/completion summary by email.
Task 2 – Pressure Transducer Procurement and Installation The Consultant shall procure, install, and initiate monitoring devices consisting of pressure transducers and conductivity probe at 5 wells as described below.
• Procure Pressure Transducers
o If requested by the City, t he Consultant shall procure up to 5 VanEssen Instruments D1272 CTD-Diver data logger or acceptable equivalent, 4 direct read cables, computer interface cable, and any suggested equipment to help data collection and/or prevent corrosion. If an alternate transducer is proposed, provide the transducer model and include justification for the City to consider the product as an alternate. • Pressure Transducer Installation
o If requested by the City, the Consultant shall install monitoring devices at one or more of the foll owing wells: 19E1, 19M 5, 19M6, 19B1, and 19B2 . Additional well details are presented in Table 1 and Table 2 and are further described in the sections below. • Program and Initiate Pressure Transducers
o The Consultant shall program and initiate all transducers to collect water level data at 3- hour intervals. The Consultant shall be responsible for downloading data and reset of transducers (if needed) at the sampling frequency outlined in Table 3. • Monitoring Device Replacement
o Upon dis covery of a transducer or conductivity probe failure , t he Consultant shall procure, install, program, and initiate a replacement monitoring device no later than the next quarterly monitoring event.
Deliverables:
1) PDF specifications and/or operating manuals for pressure transducers and equipment by email. 2) Transducer installation information , including, equipment make/model /serial numbers, depth of
transducer installatio n, manual groundwater elev ation at time of install ation, and any ot her information necessary to convert t he r aw pressure data into depth to water and g roundwater elevation.
3) Data collection form for each event outlined in Task 3, Ta ble 2. The form shall include data collection date and time, re -initiation data collection time interval (if reset), and any other pertinent information related to pressure transducer data.
Task 3 – Groundwater Well Sampling Services
A total of 20 wells at 10 distinct locations shall be sampled for this Project at the frequency shown on Table 2. The Consultant shall obtain groundwater samples from these wells using details presented in Table 1 – Well Location Information and Table 2 – Well Sampling Details. Except as noted in Table 3, all g roundwater samples collected from these wells shall be delivered to the partner laboratory for sample analyses as shown on Table 3.
Notably, three locations shown on Table 1 consist of triple -nested wells including MW -A (MW-A/1, MW- A/2, and MW-A/3), MW-B (MW-B/1, MW-B/2, and MW-B/3), and MW-C (MW-C/1, MW-C/2, and MW-C/3).
Each of these triple-nested wells are contained in a single well vault. A total of four of these nested well casings (MW -A/2, MW -A/3, MW -B/2, MW -B/3, MW -C/2 and MW -C/3) contain a 2 -inch diameter schedule (SCH) 40 polyvinyl chloride (PVC) well casing liner inside a 3 -inch diameter SCH 80 well casing to depths shown on Table 2. The Consultant shall take appropriate precautions during pump, tubing, and sampling equipment deployment in these wells to ensure that the liner casings are secure and not damaged during sampling activities.
Additional groundwater sampling details are as follows:
• Prior to each quarterly sampling event, the Consultant shall coordinate with owners of acti ve production wells to en sure pumps are turned off for measurement of static groundwa ter levels and pumps can be operated to facilitate collection of water quality samples. • The Consultant shall download pressure transducer water level data from up to 19 wells as described in Task 2. Consultant shall per form maintenance on pres sure transducer and conductivity probe as necessary, including, but not limited to, troubleshooting if abnormal data exist and resetting device to maintain adequate memory capacity. Co nsultant shall monitor transducer battery life status and notify City if transducer replacement is needed. • The Consultant shall measure water levels (i.e., gauge) from up to 21 wells semi-annually in April and October and 1 1 wells quarterly in January, April, July and October of each year per Table 2.
• After measuring water levels and prior to collecting samples, each well shall be purged to remove water that has been standing within the well screen and casing that may not be chemically representative of formation water. The Consultant shall purge and sample 20 wells semi-annually in April and October of each year and 10 wells quarterly in January, April, July and October of each year per Table 2 (note: City is seekin g a waiver of pur ge requirement for well 35M2). Purge water removed from each will be discharged to an on-site sewer connection, containment, or discharge point provide by the City.
• The Consultant shall conduct groundwater monitoring and sampling in accordance with low - flow (minimal drawdown) groundwater sampling procedures as outlined in EPA publication 540/ S-95/504.
• Upon completion of groundwater purging at each well, the Consultant shall collect groundwater analytical samples in laboratory provided sample containers for analysis of total dissolved solids, chloride, sulfate, and manganese using the analytical methods shown on Table 3 (note:
City is seeking a waiver of purge requirements for well 35M2).
• Filed duplicate samples shall be collected at 10% of total samples during each event. Trip blanks, field blank, or temperature blank are not required for this project. • Additional requirements and qualifications for this task are further described in the Minimum Requirements and Qualifications of this RFP.
Purge Water Disposal
Groundwater sampling purge water will be discharged or transported as stated below:
• Off-site Transport and Disposal by Consultant – Groundwater sampling purge water from wells 20D01S (MW-1), 20D02S (MW-2), 20D03S (MW-3), 20D04S (MW-4), and 20D05S (MW-5) and 34G3 will be stored in a temporary water tank supplied by the Consultant and then transported off-site for disposal by the Consultant. Estimated purge volumes for these 6 wells are shown on Table 2. The Consultant shall be responsible for storing water and any coordination, lab analysis, or requirements of the selected waste disposal facility. The City will sign waste manifests supplied by the Consultant and waste disposal facility. • Discharge to Sewer – Purge water from wells MW -1/1, MW -1/2, MW -1/3, MW -2/1, MW -2/2, MW-2/3, MW-3/1, MW-3/2, and MW -3/3 will be discharged to a nearby sewer under existing City of Camarillo National Pollutant Discharge Elimination System discharge permit. Purge water volume estimates for these wells are shown on Table 2. • No Purge Water – Wells 34G3, 19E1, 19M6, 19B1, and 19B2 are active production wells.
Samples will be collected from sampling ports at the well head. For 35M2, a conductivity probe will be lowered into the well screen without purging the well.
Deliverables:
1) Groundwater sampling field forms showing, but not limited to, depth to groundwater, total volume purged, record of field water quality measurements, purge rates, and sampling times.
2) Explanation of any problems encountered in the field that prevented groundwater level measurements, transducer data download, or water quality sample collection, description of any issues encountered or observed that may impact data validity.
3) Field chain-of-custody forms provided to the laboratory after groundwater sampling activities.
