After construction, the well will be developed by bailing, surging, and swabbing until the water is relatively free of sediments The well head top of casing will be surveyed for elevation to facilitate groundwater gradient calculations Soil cuttings and development water generated by the well construction will be containenzed in labeled, 55 gallon steel drums with lids and left onsite pending evaluation of analytical results. 2.4 Lithologic Description of Soil During the drilling, soil samples will be collected at 10 foot intervals in a split spoon sampler fitted with brass or stainless steel sleeves The samples will be described using standard geological classifications of color, texture, mineral content, etc , and also classified according to the Unified Soil Classification System. The soil descriptions will be used to produce a lithologic log of the monitor well boring. 3.0 SAMPLING AND SAMPLE ANALYSIS PROCEDURES This section details the sampling and analytical protocol to be utilized in the collection and analysis of soil and groundwater samples for the site 3.1 General Sampling Protocol The collection of samples for laboratory analysis must be accomplished in such a way that the . sample integrity is maintained The sample will be obtained and handled so that it remains representative of site conditions for analysis 3.2 General Requirements and Documentation A hard bound field log book will be kept for the project by the sampling crew chief All data relating to the collection of samples and related field activities will be recorded in the log book Samples collected will be documented in the log book by the sample ID number, location, time, date, and sampler's initials Any observations regarding the sampling process and field related activities or the surrounding environment which may affect the sampling quality will be noted in the log book Each page of the log book will be dated along with the logger's initials and the project name Any deviations from the sample protocol or approved work plan will be entered in the log book A WESTON sample label will be affixed to every sample container and will include the following information project ID or project number, sample ID, date, time of sample collection, sampler's initials, analytes requested and preservatives used, if any A Chain-of-Custody document will be initiated at the time of sampling and will accompany the sample until it is received by the laboratory. The Chain-of-Custody form shall be protected by sealing it into a water tight plastic ziplock bag, placed with the samples during sample shipment. RvrswcM,wWnc rua 5
