1. Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal
In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only t

2. Caracterização do conteúdo de fossas e tanques sépticos na cidade de Natal
Only 32% of the population of Natal is attended by sewage, while the remaining population use pits and septic tanks. The characterization of the contents of septic tanks and pits contributes to the performance of such system and may guide the decision on treatment of these contents. The main of this research is to characterize the contents of interior reside

3. Septage treatments to reduce the numbers of bacteria and polioviruses.
Disposal of the pumped contents of septic tanks (septage) represents a possible means of dissemination of enteric pathogens including viruses, since persistence of enteroviruses in septic tank sludge for greater than 100 days has been demonstrated. The risk of exposure to potentially infectious agents can be reduced by disinfecting septages before their disp

4. Entrainment of Viruses from Septic Tank Leach Fields Through a Shallow, Sandy Soil Aquifer
A study was conducted which focused on movement of naturally occurring human enteroviruses from a subsurface wastewater disposal system through a shallow aquifer. The potential for significant entrainment of virus particles was evidenced by their recovery at down-gradient distances of 67.05 m and from aquifer depths of 18 m. A significant negative correlatio

5. Use of Antibiotic Resistance Analysis To Identify Nonpoint Sources of Fecal Pollution
A study was conducted to determine the reliability and repeatability of antibiotic resistance analysis as a method of identifying the sources of fecal pollution in surface water and groundwater. Four large sets of isolates of fecal streptococci (from 2,635 to 5,990 isolates per set) were obtained from 236 samples of human sewage and septage, cattle and poult

6. Incidence of Enteric Viruses in Groundwater from Household Wells in Wisconsin
Recent studies on the contamination of groundwater with human enteric viruses have focused on public water systems, whereas little is known about the occurrence of viruses in private household wells. The objective of the present study was to estimate the incidence of viruses in Wisconsin household wells located near septage land application sites or in rural
