The purpose of this study is to support the District in evaluating the impact of septic infrastructure on surface water quality in streams within the 15-county metro Atlanta area. Specifically, this study will employ time-sensitive sampling techniques to assess the effects of rain events on interactions between septic system characteristics (e.g., system age and density) on surface water conditions that compromise human health and the environment. Four watersheds were considered: Little Stone Mountain Creek, Honey Creek, Pond Creek, and West Fork Little River. River level and discharge thresholds were developed based on flood frequency analysis to determine the trigger points for the automated water quality sampler to obtain measurements due to a wet weather event.
