"Authorization To Discharge Groundwater to Agua Hedionda Creek From Carlsbad Municipal Water District's Calavera Hills Offsite Sewer Extension Construction Dewatering Project Carlsbad, CA," dated April 12, 1999, WDID No. 9 000 000 882, by California Regional Water Quality Control Board San Diego Region. 2. "General Permit Authorization Application for Groundwater Extraction Discharge, Offsite Sewer Improvements, Calaveras Drive Station 24+74(±) to El Camino Real, Calavera Hills Development, City of Carlsbad, San Diego County, California," dated March 29,1999, W.O. E2606-SC, by GeoSoils, Inc. Dear Ms. Ghoram: As required by the above referenced authorization letter by the San Diego Regional Water Quality Control Board (RWQCB), GeoSoils, Inc. (GSI) is providing the following monitoring information on groundwater discharge into Agua Hedionda Creek. The dewatering program started the afternoon of April 14,1999. Excavation for the sewer line started on April 22,1999. Information provided herein includes daily field monitoring memos from April 15 to 28,1999 and available chemical laboratory data from Groundwater Monitoring Sample Number 1 (G.M.S. #1) collected on April 19,1999. Brief Summary of Daily Field Observations Overall, the volume of extracted groundwater discharged into the creek ranged during this period from approximately 144,000 ± gallons per day to 175,000 ± gallons per day. The lower value represented discharge from the series of 36, 2-inch diameter well points. The later volume represented the additional discharge from the 2,12-inch diameter wells, B-1 and B-2. Reid daily memos are provided in Appendix A. c c c E C C c c c C Sandbags were placed near the discharge pipe in the creek to effectively limit erosion. Except for a small depression directly under the pipe, no signs of erosion were noted near the discharge point. Generally, unusual odors, discoloration, and/or floating materials (i.e., silt/clay particles) were not detected in groundwater discharged into the creek. Short term exceptions (i.e., less than 3 ± hours), occurred when utility excavations were directly adjacent to well B-1 (see Memo dated April 22), and after the system was restarted subsequent to repairs (see Memo dated April 27). Field observations of the creek roughly 100 ± feet down-gradient from the discharge point typically noted no unusual physical conditions to the flow generated by the extracted groundwater. During this monitoring period, creek flow along the western El Camino Real bridge abutment appeared to be generated by solely by discharged groundwater from the subject system. Obvious signs of erosion were not observed, due to the limited flow and the established native vegetation at the southern edge of the bridge. Small depositional features (i.e., alluvial fanlets) were noted under the bridge, but did not extend to the vegetation boundary. Noxious odors, associatecl with the offsite connection to a live sewer main in Cannon Road, was detected at the southerly bridge abutment. Chemical Laboratory Test Results As directed in the above referenced authorization letter by the RWQCB (dated April 12, 1999), groundwater samples were collected and analyzed on a regular basis. G.M.S. #1 was collected from the discharge outlet pipe in the creek on April 19,1999. The sample was analyzed for total nitrogen, total phosphorous, total and fecal coliform, zinc, dissolved oxygen, acute toxicity, and pesticides (including diazinon) by EPA test method 8140. Samples were collected, stored and transported to California Department of Health Services (DHS) certified laboratories (Pacific Analytical Services, Inc. and Environmental Engineering Laboratory) the same day, following proper procedures. A Chain-of-Custody record was recorded with each laboratory. p At this time, test results are available for dissolved oxygen (4.0 mg/l), total coliform (< 2 I MPN/100 ml), fecal coliform (< 2 MPN/100 ml), phosphorus (not detected), zinc (not detected), Kjeldahl nitrogen (0.55 mg/l), and nitrogen as nitrate 15.6 mg/I (NOa). Test C results for acute toxicity and pesticides will be provided as soon as they are available. Maximum contaminant levels provided in Regional Board's Order No. 96-41 indicate limits were exceeded for dissolved oxygen and nftrogen. The table below provides a summary P- of laboratory test results and the applicable specific effluent limitations from Order 96-41. ^ Laboratory test methods, complete test results, and the Chain of Custody documents are provided in Appendix B.

Test results will be submitted as spoon as they become available. Conclusions and Recommendations Based upon the daily field observations and initial laboratory test results of G.M.S. #1, GSI concludes that overall, the extracted groundwater discharged into Agua Hedionda Creek has not substantially affected the surface water quality of the creek. Low concentrations of dissolved oxygen may be potentially impacted by algae growth on the holding tank. The high concentration of nitrogen (as nitrate) may be related to the up-gradient agricultural development. It is our understanding that the main dewatering system will be offline by April 30,1999; however, groundwater discharge from individual well points will continue along the sewer line until construction is completed. This should substantially decrease the volume of groundwater discharged into the creek over the next 2 weeks. In the interim, to increase the dissolved oxygen content of the discharged groundwater, GSI has requested the contractor (T.C. Construction) to insert air ports/holes in the pump discharge pipe to aerate the groundwater. California RWQCB Calavera Hills Development File:e:\wp7\env\e2600\e2606.mm W.O.
