We are still in the part of re- <br /> engineering our chlorine control system and we are still manual- <br /> ly adjusting chlorine and sulfur dioxide levels so as to best <br /> meet disinfection and de-chlorination requirements. We have no <br /> domestic influent flow data for the month of September; our flow <br /> meter has been inoperative and is being re-engineered so that it <br /> will work. Specific conductance data for the month is also <br /> lacking because our conductivity bridge was being serviced. <br /> If you have any comment, regarding this data, please call. <br /> Sincerely, <br /> WASTEWATER TREATMENT PLANT <br /> --- <br /> DARRELL SCOTT <br /> Lab Technician <br /> cc: San Joaquin Health District <br /> DS: mg <br />
