Ramcon Standard Procedure <br /> Standard Procedure 8 Revl 7/95 <br /> Water Grab Sample Collection from Soil Borings and Hydropunch Apparatus <br /> See Also Procedure: Drilling and Sampling with Hollow-Stem Auger Equipment, Sample <br /> Handling, Sample Equipment Decontamination, Quality Assurance/Quality <br /> Control <br /> Limitations: These procedures have been developed and adopted for utilization <br /> primarily for the assessment of fuel and motor oil constituents at <br /> underground storage tank or fuel spill sites. <br /> The water samples collected and subsequently analyzed by this <br /> method are a "snapshot" of groundwater conditions at the time and <br /> place of collection. They are effectively utilized as a screening tool <br /> to evaluate lateral limits of groundwater contaminants and in the <br /> subsequent location of properly constructed and developed <br /> monitoring wells. The method is not designed, nor is it intended to <br /> provide comprehensive gradient information. Our experience with <br /> the method indicates that samples are frequently cloudy and contain <br /> silt. Incorporation of this material in water samples is often <br /> unavoidable. Particular attention and care should be devoted to <br /> sample analysis under these limitations,including matrix interference <br /> with petroleum hydrocarbons and,particularly with false positives in <br /> metals analysis. <br /> Equipment: <br /> -Iced Insulated Cooler -Hydropunch sampler <br /> 4 liter amber glass and 40 ml VOA containers -Licensed WellDriller <br /> -New, polyethylene rope from a sealed w/HSA drilling equipment <br /> package -Sample Labels <br /> -Polyethylene disposable bailer or -Chain of Custody <br /> stainless steel bailer, small diameter -Indelible Ink Marker <br /> -Hydropunch well points and screen -Field Note Book <br /> Stipulation - Borings are regulated by code and permits are required in most localities. Grout <br /> inspection by the regulation agency is typically required and is scheduled in advance. <br />
