Exogenous Carbon Source

During the process of sporulation, the oxidation rate of exogenous carbon source, acetic acid, is high during a period lasting from 1 to 4 h. Then it falls rapidly and the metabolism of acetic acid seems to be deflected. Endogenous oxidation rate rises rapidly at the beginning of the process and reaches its maximum after a 12- to 16-h contact with the sporulation medium. Then it falls regularly.

The Impact

One of the key threats to groundwater and surface water quality in Ireland is the impact of poorly designed, constructed or maintained on-site wastewater treatment systems. An extensive study was carried out to quantify the impact of existing sites on water quality. Six existing sites, consisting of a traditional septic tank and soakaway system, located in various ranges of subsoil permeabilities were identified and monitored to determine how well they function under varying subsoil and weather conditions. The preliminary results of the chemical and microbiological pollutant attenuation in the subsoil of the systems have been assessed and treatment performance evaluated, as well as impact on local surface water and groundwater quality. The source of any faecal contamination detected in groundwater, nearby surface water and effluent samples was confirmed by microbial source tracking. From this, it can be seen that the transport and treatment of percolate vary greatly depending on the permeability and composition of the subsoil.
