Box 100 <br />Sacramento, CA 95814 <br />L A MOLDENHAUER. P E. <br />CHARLES W. CUNNINGHAM, P <br />Attention: Jean Ladyman <br />Subject: Santos Ranch Development, San Joaquin County, California <br />— Section 205 (j) Clean Water Act Grant Application for Ground <br />Water Study. <br />Greetings: <br />The attached application for the above study is prepared and subm <br />for the Santos Ranch Development Citizens Committee, who have <br />requested that San Joaquin County act as the contracting agency for <br />this study. This Citizens Committee has stated in writing .(See Appendix <br />_ G of this application) that they will be responsible for the local share <br />funds (25%) when the gran' c ffer is made. <br />The Santos Ranch Development has a very high ground water table into <br />which septic tank leachate is discharged via conventional leaching trenchs. <br />Approximately 400 people and a school (225 students and staff) pump <br />their potable water supply from the shallow aquifers under this urban <br />development. This possible health and safely problem is further a.ggrivated <br />by very high Nitrate concentrations in said drinking water supply (NO3 <br />at concentration levels of 69 mg/l to 90 mg/ls) and also high Total Disolved <br />Solids concentration from 1000 mg/l to 1500+ mg/1. <br />The citizens committee hopes to secure contracting support from San <br />Joaquin County in the very near future. <br />Sincerely, <br />L.A.
