J. H. KLEINFELDER & ASSOCIATES <br /> File: S-1008-21/12 :337 <br /> Revised: July 8, 1986 <br /> Page 8 <br /> ANALYTICAL PARAMETERS <br /> An assessment of the existing water quality conditions will <br /> be made after the ground water monitoring wells are installed. <br /> The initial water quality samples will be analyzed for parameters <br /> specified in the California Administrative Code, Title 22 , used <br /> to assure potability. For the Harney Lane Landfill , the <br /> inorganics and general minerals as specified in Title 22 are <br /> recommended. These parameters should be monitored on an annual <br /> basis. Unless the initial or annual extensive list of analyses <br /> indicates that certain parameters exceed allowable limits, the <br /> intermediate quarterly tests will be limited to specific <br /> conductance, pH, hardness, COD, chloride, and total nitrogen. <br /> The predominant organic contaminant found in ground waters <br /> underlying some landfills are the volatile organics. For this <br /> reason, testing for EPA Method 624 purgeable volatile organics <br /> will also be performed initially and on an annual basis. A <br /> complete list of the analytical parameters to be tested on an <br /> annual basis is shown on Table 1 . <br /> SAMPLING OF GROUND WATER MONITORING WELLS <br /> As stated in the previous sections, each of the ground water <br /> monitoring wells will be equipped with dedicated pumps. This <br /> will allow simplified sampling procedures and decrease the <br /> potential for biasing the representative nature of the collected <br /> samples. The sampling procedures which will be followed at the <br /> Harney Lane Landfill are as follows: <br /> o Prior to purging,' the water level will be determined in <br /> each well . <br /> o pH, temperature, and specific conductance or electric <br /> conductivity will be measured as the well is being <br /> purged. <br /> o Samples will be collected in appropriate sample <br /> containers supplied by the contract laboratory. These <br /> will be polyethylene jars for inorganic parameters, and <br /> glass jars when analyzing for organic contaminants. <br /> Containers for metal analyses will be acid fixed. <br /> o Each sample will be properly identified and labeled and - <br /> stored on ice. <br />
