MONITORING AND REPORTING PROGRAM -7- FORWARD INC.,FORWARD LANDFILL SAN JOAQUIN COUNTY Ground water sampling shall also include an accurate determination of the ground water surface elevation and field parameters (pH, temperature, electrical conductivity, turbidity)for that Monitoring Point or Background Monitoring Point. Ground water elevations taken prior to purging the well and sampling for Monitoring Parameters shall be used to fulfill the ground water gradient/direction analyses required. For each monitored ground water body, the Discharger shall measure the water level in each well and determine ground water gradient and direction at least quarterly,including the times of expected highest and lowest elevations of the water level for the respective ground water body. Ground water elevations for all background and downgradient wells for a given ground water body shall be measured within a period of time short enough to avoid temporal variations in ground water flow which could preclude accurate determination of ground water gradient and direction. This information shall be included in the quarterly monitoring reports. Statistical or non-statistical analysis shall be performed as soon as the monitoring data are available. 3 . Constituents-of-Concern 5 Year Monitoring Program In the absence of evidence of a release being indicated,the Discharger shall monitor all Constituents of Concern as follows: The discharger shall sample all Monitoring Points and Background Monitoring Points for each monitored medium for all COCs every fifth year, beginning with the Winter of 1995 (first Reporting Period ends 31 March 1995), with subsequent COC monitoring efforts being carried out every fifth year thereafter alternately in the Summer(Reporting Period ends 30 September) and Winter(Reporting Period ends 31 March). D. WATER QUALITY PROTECTION STANDARD The Water Quality Protection Standard (Standard) shall consist of the following elements: 1. Constituents of Concern; 2. Concentration Limits; 3. Monitoring Points; 4. Points of Compliance; 5. Compliance Period. In addition to these elements, Monitoring Parameters shall also be established.
