Protect your drinking water well from going dry

When dry or drought conditions exist, water conservation measures could reduce the likelihood of your well going dry.

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.


Testing Recommendations for Private Drinking Water Wells

While many private water systems provide water that is safe and of good quality, it is not uncommon to have one or more water quality problems. Some such as iron or hydrogen sulfide are quite noticeable. Others, particularly those that are health concerns such as nitrate and pesticides, often require testing to detect.

Unlike public water systems, private well owners in most states are not required to regularly test their wells or correct water quality problems. It is each individual …

Selecting a Home Water Treatment System


Home Water Treatment Devices

The table below outlines information on specific home water treatment approaches. Keep in mind that some water treatment can be for aesthetic as well as health factors. If drinking water poses a health risk, the consumer may also consider the cost of purchasing bottled water or tying into a public water system if available as an alternative to treatment.
If you need to contact a water treatment professional to install or repair a home treatment system or to assess a …

Drinking Water Treatment – Reverse Osmosis

EFFECTIVE AGAINST: Inorganic contaminants such as: dissolved salts of sodium, dissolved (ferrous) iron, nitrate, lead, fluoride, sulfate, potassium, manganese, aluminum, silica, chloride, total dissolved solids, chromium, and orthophosphate. Also effective in removing some detergents, some taste, color and odor-producing chemicals, certain organic contaminants, and some pesticides.

NOT EFFECTIVE AGAINST: Dissolved gases, most volatile and semi-volatile organic contaminants including some pesticides and solvents. Alone, reverse osmosis units are not recommended for treatment of bacteria and other …

Drinking Water Well Quality Basics

Groundwater, the source of water for private wells, is never simply a pure combination of hydrogen and oxygen atoms (H20). It contains many impurities, reflecting the composition of the soils, sand, gravel, and rock through which it travels. Groundwater naturally contains:

  1. Dissolved minerals such as iron, calcium, magnesium, bicarbonate, chloride, and sulfate
  2. Gases such as carbon dioxide, oxygen, and nitrogen
  3. Dissolved organic compounds

As a result of human activity, groundwater can also contain contaminants such as pesticides, nitrate, metals, …
