Equipment Decontamination SOP any solid particles from the equipment or material. If solids have adhered to the equipment, saturate a clean paper towel or rag with a quick dry solvent such as isopropyl alcohol, and wipe down the equipment until solids have been removed. 2. Triple rinse equipment with analyte-free water and collect rinsate water in a plastic bucket. 3. Dispose of the rinsate water by thin spreading in an absorbent area of the site (ex. on grass or soil). 4. If time permits,place equipment on a clean surface and allow to air dry. If equipment is needed immediately for use, ensure that the equipment has been thoroughly rinsed with analyte-free water and wiped with a new shop rag or paper towel to remove excess water. Decontamination by Hand Washing with Detergent Hand washing using a detergent such as Alconox is performed when contamination is known or suspected to be present, and particularly when organic constituents are involved. This method applies when triple rinsing is not sufficient to remove contaminants. I. Rinse equipment with analyte-free water and collect all rinsate water in a plastic bucket. 2. Create a detergent mix using analyte-free water and selected detergent following approved product concentrations. Using appropriate brush and detergent, scrub all areas of the equipment that may have been in contact with contamination. 3. Rinse equipment again with analyte-free water and inspect equipment. Repeat this process as many times as necessary until equipment is visually clean. 4. Allow to air dry for 15 minutes or wipe dry with a clean cloth or paper towel. 5. Properly dispose of all rinsate water(see Waste Management SOP) after equipment blanks are collected (if applicable). Wash or appropriately discard any contaminated PPE. Note: Rinsate containing detergents cannot be discharged to ground or storm drain! Decontamination of a Portable Pump 1. Rinse pump and discharge line by spraying analyte-free water on the exterior components where contact is made with contaminated well water. 2. Insert the pump into a 55-gallon drum containing analyte-free water and purge the discharge lines for approximately 5 minutes. 3. Collect all rinsate and purge water and properly dispose of(see Waste Management SOP). Decontamination of Sampling Equipment The following procedure shall be used to decontaminate small sampling equipment such as split spoons, reusable bailers, trowels/spoons and bowls: 1. Scrub the equipment with a solution of potable water and low-phosphate soap(e.g., Alconox). 2. If metals are contaminants of concern, rinse equipment with a 10% acid solution followed by a rinse with deionized water. Use spray bottles to minimize acid waste generation. Collect acid waste in a separate container. 3. If organic constituents are contaminants of concern, rinse the equipment with a pesticide- Control#:AG-20001-00 Page 6 of 8 File Name:Equipment Decontamination SOP
