Which onsite septic system effluent components of wastewater are helpful or harmful to soils or nearby waterways?

Effects of septic or sewage wastewater on soils:

This article includes a table describing the effects of common wastewater constituents on arid soil, tropical and temperate soil, and on both ocean water and fresh water bodies.

These effects of eleven principal septic tank efflent constituents on soil and water bodies vary widely from beneficial to very harmful and highly undesirable.

Effects of Septic Effluent Components on Soil & Water in the Environment

The chart below, discussion, and nearly forty research reference citations address the effects on soil or land and water environments of the discharge of nitrogen, organic compounds, water discharged in onsite wastewater disposal systems such as common septic tanks, drainfields, seepage pits, drywells, and soakaway beds disposing of both graywater and blackwater or sewage effluent.

WATER SOFTENER IMPACT on SEPTIC

Notes to the table above

1. Chlorine / bleach impacts:

at sufficient concentrations chlorine may kill off or reduce the level of septic tank bacteria that are needed for effective wastewater processing. At normal home usage levels we do not expect to see an effect. Some septic systems require disinfection of wastewater before it is discharged to the environment.

2. Industrial toxins in ocean water:

Even though diluted, may bio-concentrate in various life forms, moving up food chain to humans

3. Organic compounds:

at a particulate level such as food waste, organic material in wastewater may add to septic tank volume and require more frequent pumping to avoid disposal field clogging where private septic systems are involved. Grease discharged into septic systems and sewers can cause clogging and failures.

4. Nitrogen impact on water:

Nitrogen is potentially harmful in ocean water by encouraging growth of algae, but dilution in ocean envrionment probably means there is no measurable effect

5. Pathogenic microorganism discharge in wastewater impact on wastewater, septic tanks, soils:

"harmlessly biodegrade" in soils is probably accurate in general but may not be in septic tanks and wastewater treatments connected to health care facilities. A corrolary problem is the high concentration of antibiotics in wastewater produced by health care facilities, nursing homes etc., - at levels that can damage or destroy essential bacteria in septic tanks and in the soils receiving wastewater.

6. Phosporous impact on ocean water: 

Phosphorous is potentially harmful in ocean water by encouraging growth of algae, but dilution in ocean envrionment probably means there is no measurable effect

7. Salt impact on soils & waterways:

Burks & Minnis (1994) and others have researched the impact of salt on septic system failure.

8. Water impact on soils:

 although water volume discharge may be beneficial in general, water discharge in a volume sufficient to flood a septic disposal field is highly undesirable as results include septic system failure, sewage backups even into the building, and the discharge of un-treated wastewater into the environment.

    Abstract:
    The authors obtained 50 vegetable samples from various regions in Morocco and examined them to determine the micro biological quality of these products. Aerobic count, coliform, enterococci, and Staphylococcus areus were evaluated.

    This analysis revealed high levels of enterococci, fecal coliforms, and total coliforms. No coagulase-positive Staphylococcus aureas was detected in any of the samples analyzed. Biochemical identification of Enterobacteriaceae showed the presence of Citrobacter freundii (28 percent), Enterobacter cloacae (27 percent), Escherichia coli (16 percent), Enterobacter sakazakii (12 percent), Klebsiella pneamoniae (17 percent), Serratia liquefaciens (11 percent), and Salmonella arizonae (0.7 percent).

    The results clearly demonstrate that vegetables irrigated with untreated wastewater have a high level of microbiological contamination. Consequently, these vegetables may be a threat for the Moroccan consumer and may be considered a serious risk to Moroccan public health.
