Before and after each subsequent soil and/or groundwater sampling event, all sampling <br /> equipment will be cleaned. Cleaning will consist of removing solid material from the <br /> sampling equipment using clear water and plastic bristle brush, washing the sampling <br /> equipment in a mixture of clear water and Liqui-Nox or Alconox (the use of phosphate based <br /> detergents will not be allowed), rinsing the sampling equipment in clear water, rinsing with <br /> deionized water, and allowed to air dry. <br /> page 18 <br />
