Source water is a finite resource thatneeds to be protected for the long-term benefit ofhuman health. The current approach for protection ofsource water is two-fold: assessment of existingvulnerability of a source water watershed tocontamination and development of a protection plan.The US Environmental Protection Agency USEPAand Georgia Department of Natural ResourcesEnvironmental Protection Division GAEPD haveprovided extensive guidance on how to conduct asource water assessment; however, relatively littleguidance exists on how to prepare and implement aprotection plan. Source Water Assessment PlansSWAPs for twenty-eight Metro-Atlanta water supplyintakes were completed in 2001 by the AtlantaRegional Commission ARC . These Assessmentsindicate that some intakes have a potentially highsusceptibility to pollution due to the density ofcontaminant point sources and high amounts ofimpervious surface indicator of nonpoint sourceimpacts. The source water protection strategiesdescribed herein outline a framework for localprotection plans and provides a number of strategiesthat are appropriate for source water watersheds ofdifferent sizes and levels of impact.The recommendations in this document includeprogrammatic recommendations that would be appliedin each of the jurisdictions as well as pollution sourcespecific strategies. Programmatic strategies includeimplementation of the Metropolitan North GeorgiaWater Planning District Model StormwaterManagement Ordinances adopted in October 2002 toaddress nonpoint source loadings, implementation ofthe G AEPD Environmental Planning Criteria to requireset backs from streams in source water watersheds,better enforcement of existing regulations, andacquisition and preservation of land within source waterwatersheds.A number of unique challenges exist in thedevelopment of source water protection strategies,some of which overlap with recommendations fromTotal Maximum Daily Load TMDL implementationstrategies being developed simultaneously.Implementation of effective nonpointsource-stormwater control measures will address manyof the primary sources of pollution contributing to bothwater quality impairments associated with TMDLlistings and potential source water contamination. Inorder to minimize costs, source water protectionstrategies should be combined, to the extent possible,with watershed protection and management programs.
