During the quarterly sampling of Ciruela Canyon, no flow existed at Station CCS-1. Analysis of the sample collected just above Station CCS-2 (below the mine water discharge and coal refuse disposal area) indicated an elevated level of pH, conductivity, turbidity, hardness, iron, and manganese over that sampled at the mine discharge (Table 2-7). This flow, however, is not having direct effects on the Purgatoire River because of its absorption into the Ciruela and Purgatoire alluvium. Flume stations were established on Apache and Santistevan Canyon on 5 April and 19 April, 1984, respectively. A no flow condition existed in Apache Canyon during the monitoring quarter (Table 2-9). Four days of flow were recorded during the monitoring period in Santistevan Canyon (Table 2-11) which indicated base flow conditions. 3.0 Ground Water Monitoring Monthly ground water samplings were conducted at each of the five designated stations PAW-l, PAW-2, PAW-3, CCAW-1 and ACAW-1 on 6 to 8 March, 28 and 29 March, and 24 April. 3.1 Methods The three Purgatoire alluvial wells have been in place for a number of years and exact time and method of installation are not known, however, the four-inch steel casing is completed to a depth of approximately 25 feet in each and no development or pumping records are known to exist. Stations CCAW-1 and ACAW-1 have not been installed as of the end of the quarter. Depths to water below the top of the well casing was measured to the nearest hundredth-foot using an electric line water level detector. The elevation at the top of the well casing was subtracted from the depth to water to obtain the ground water elevation. VVater quality was sampled in the field directly from the wells with a hand bailer. The wells were cleared by bailing at least three columns of water prior to collecting the sample. Equipment and procedures used for water chemistry analysis was consistent with that described in Section 2.1 (Surface Water Monitoring Methods).
