is to ensure that injection dosages are sufficient to meet chlorine demand and maintain adequate residuals in the entire distribution system, including vulnerable portions of the system. Vulnerable areas are anywhere we might have increased water age or stagnant water (storage tanks, high elevation/low pressure, low occupancy, dead ends). We use these chlorine residual results along with other information to focus our best management practices such as line and hydrant flushing (along with valve exercising). Methodology and Reporting Our certified <operator/sampler> uses a <specify equipment here> to measure chlorine residuals and follows all sample collection, handling, measuring and equipment calibration protocol specified in the operation manual. All chlorine residuals that are measured during RTCR routine and repeat sampling and for best management practices. These results are required to be recorded on the bacteriological chain of custody forms that are submitted to the lab and are also recorded on the Residual Disinfectant Residual Measurement Sampling Report (Appendix E). We submit this report to our DWB CO by the 10th day following each quarter, as required. Compliance Our water system is in compliance if: We maintain chlorine residuals less than or equal to 4.0 mg/L, the Maximum Residual Disinfectant Limit (MRDL) We submit our Residual Disinfectant Residual Measurement Sampling Report to our DWB CO no than the 10th day following each quarter Section 4: Lead and Copper Rule (LCR) Sampling Frequency We are required to collect five (5) Lead and Copper samples once every three (3) years. We use Drinking Water Watch to keep track of this sampling schedule (Appendix A). Location Sample locations are based on the age and types of structures we have in our community, including schools. We have included guidelines for site selection and sampling in Appendix F of this plan. Based on these criteria we have selected the main and alternate locations designated in the
