The recognition that septic systems can generate groundwater plumes with nitrate concentrations exceeding the drinking water limit has led to a need for improved nitrogen removal in septic systems. Long-term (3 to 5 year) monitoring results are prese

A new method for the treatment of wastewater phosphate is presented that relies on reductive iron dissolution (RID process). It is analogous to existing treatment methods that use iron salts (e.g., FeCl 2 ) to precipitate P from wastewater, except th

Aqueous geochemical data from unconfined sand aquifers beneath two operating domestic septic systems are used to illustrate and evaluate a conceptual model of septic-system geochemistry. This model emphasizes the changing redox and alkalinity conditi

Septic systems in lakeshore environments often occur where thin soils overlie bedrock and, consequently, filter beds may be constructed of imported filter sand. The objective of this study was to assess the mobility of wastewater phosphorus (P) in su

The abundance of Scylla serrata in two closed estuaries, the Mhlanga and the Msimbazi, in Natal, South Africa, was estimated by means of the mark-recapture models of Chao, Burnham and Overton, and Petersen. In view of the size-related variability in
