Setback Distance From Septic to Drinking Water Well

Many rural residents use an on-site wastewater treatment system (an individual septic system) for treatment and disposal of wastewater, or sewage. Household wastewater may contain contaminants such as disease-causing bacteria, infectious viruses, household chemicals, and excess nutrients. A properly designed, installed, and maintained septic treatment system will reduce the risk of polluting the drinking water supply with these contaminants.

State and local codes specify how on-site wastewater treatment systems must be designed, installed, and maintained. A septic tank and …

Drinking Water Treatment – Filtration

EFFECTIVE AGAINST: Small particles and suspended solids such as ferric iron, clay, silt and sand, and some pathogens such as bacteria and viruses, and colloids (suspended matter).

NOT EFFECTIVE AGAINST: Any dissolved contaminants such as nitrate, dissolved iron, sodium, and volatile organic compounds (VOCs).


Water Quality Protection Around Your Home

Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
Once polluted runoff enters our water resources, it can be very difficult and expensive to clean up. Each of us can take actions …

Drinking Water Treatment – Distillation

EFFECTIVE AGAINST: Some heavy metals, dissolved solids, some bacteria and viruses, inorganic materials such as nitrate, sodium, fluoride, and sulfate, and some toxic organic chemicals.

NOT EFFECTIVE AGAINST: Most volatile and semi-volatile organic compounds (VOCs), and some bacteria.



Distillation is …

If your drinking water well goes dry, you need to consider local conditions affecting your well. Is there a drought that is worse than usual? Has this happened during other droughts? Are your neighbors experiencing similar problems? Have you observed other changes in your well, such as changes in taste or smell of the water? Is there a new industrial, commercial, or …

Drinking Water Treatment – Cation Exchange Units

EFFECTIVE AGAINST: Positively charged ions such as iron, magnesium, calcium or manganese.

NOT EFFECTIVE AGAINST: Negatively charged ions, such as nitrates, bicarbonate, sulfate, selenium, and some compounds of arsenic.


Drinking Water Treatment – Anion Exchange Units

EFFECTIVE AGAINST: Negatively charge ions, such as nitrates, bicarbonate, sulfate, selenium, and some compounds of arsenic.

NOT EFFECTIVE AGAINST: Positively charged ions such as iron, magnesium, calcium or manganese.


Drinking Water Treatment – Aeration

EFFECTIVE AGAINST: Aeration water treatment is effective for management of dissolved gases such as radon, carbon dioxide, some taste and odor problems such as methane, and hydrogen sulfide, as well as volatile organic compounds, like MTBE or industrial solvents. It is also effective in precipitating dissolved iron and manganese. Aeration raises the pH of water.

NOT EFFECTIVE AGAINST: Aeration is not effective for removal of heavy metals, or pathogenic (disease-causing) organisms like bacteria and viruses.
