Kellogg Garden Products ECO:LOGIC Engineering Groundwater Monitoring Well Installation Work Plan KELG04-001 11/10/2004 (temperature, pH, and electrical conductivity) will be monitored during purging. Purging will continue until the field parameters vary by less than 10% for successive purge volumes. Data will be recorded on well- specific data sheets(see attached example). It is possible that the wells may run dry prior to purging three well volumes. If this occurs,samples will be collected as described below. Samole collection Vater samples will be collected with the pump or bailer used to purge the well. In the event the well pumps or bails dry during purging,water levels will be allowed to recover overnight and samples will be collected from the first water pumped or bailed from the well on the following day. Ouality Assurance/Quality Control All data collection will be in accordance with proper sampling and field measurement procedures as outlined below. The QA/QC program components for the field include: o Decontamination of field sampling equipment o Calibration of all field measuring equipment o Sample logging and chain of custody procedures o Sample labeling o Ensuring that all samples are obtained,maintained,and shipped according to QA/QC procedures Decontamination Non-dedicated sampling equipment will be cleaned by hand after each sample is collected to avoid cross- contamination between sample events. All cleaning of equipment shall be conducted on polyethylene sheeting or in bins. Cleaning will include: 1. Removing adhering soil particles by scrubbing with a hand brush in solution of potable water and a non-phosphate detergent(Alconox). 2. Rinsing with deionized or distilled water. Rinsing with free-flowing deionized or distilled water. 3. Rinsing with chlorine solution prepared with deionized or distilled water. Dedicated hand bailers will be rinsed first with potable water and then with deionized or distilled water. If this does not result in acceptable cleating of the bailer(e.g. soil particles adhere to the bailer)decontamination will follow that of non-dedicated equipment. Field Forms A field notebook containing all field forms for activities conducted during the field program will be maintained. Information conceming sample collection procedures, sample identification, and any other pertinent infomtation or observations will be recorded on the field forms. Copies of the field forms will become part or the project file or Facility Operating Record for further reference. Sample identification A sample identification system will be used to identify each sample location and sample type collected from the facility. This will provide a tracking system to allow for retrieval of information and to insure that each sample is uniquely numbered. Each sample identification will consist of the following: o Site identification o Date sampled o Sample location o Sample sequence number. 8
