South Deschutes County Water Filtration

Extensive field research and study has shown that the groundwater underlying south Deschutes County is threatened by continued use of traditional onsite wastewater treatment (septic) systems (standard, pressure distribution and sand filter systems). In addition, the La Pine National Demonstration Project showed that new types of onsite systems can protect the groundwater in a manner that meets the adopted Comprehensive Plan goals for Regional Problem Solving for South Deschutes County.


The tanks on the right are filtration tanks which we can install in your pump house to help keep your water clean.

Deschutes County requires lab tests for all new and improved wells.  Wells must be tested for potability, nitrates, arsenic, and tests usually include results on water hardness and ph.  The argument is that groundwater pulled by pumps in areas less than 24″ from the surface could contain unsafe levels of harmful items, due to lack of proper ground filtration.

There are several ways to correct this problem based on the problem you have:

  • Install a different, more advanced septic system determined by the county.
  • Drill a deeper well and/or,
  • Filter the water which is pulled from the well

 We can help fix it!

What Are Nitrates?

  • Nitrate is a colorless, odorless, and tasteless compound that is present in some groundwater in Oregon.
  • Nitrate can be expressed as either NO3 (nitrate) or NO3-N (nitrate-nitrogen). Nitrate levels above the EPA Maximum Contaminant Level of 10mg/l NO3- N or 45 mg/l NO3 may cause methemoglobinemia in infants.
  • Proper management of fertilizers, manures, and other nitrogen sources can minimize contamination of drinking water supplies.

Nitrate (NO3) is a naturally occurring form of nitrogen found in soil. Nitrogen is essential to all life. Most crop plants require large quantities to sustain high yields.

Although nitrate occurs naturally in some groundwater, in most cases higher levels are thought to result from human activities. Common sources of nitrate include:

  • fertilizers and manure,
  • animal feedlots,
  • municipal wastewater and sludge,
  • septic systems, and
  • N-fixation from atmosphere by legumes, bacteria and lightning.

Health Effect of Nitrates


High nitrate levels in water can cause methemoglobinemia or blue baby syndrome, a condition found especially in infants under six months. The stomach acid of an infant is not as strong as in older children and adults. This causes an increase in bacteria that can readily convert nitrate to nitrite (NO2). Do not let infants drink water that exceeds 10 mg/l NO3-N. This includes formula preparation.  Read More…

What is Arsenic?

The United States Environmental Protection Agency (EPA) regulates arsenic in drinking water to protect public health. Arsenic may cause health problems if present in public or private water supplies in amounts greater than the drinking water standard set by EPA.

Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. It enters drinking water supplies from natural deposits in the earth or from agricultural and industrial practices.

Uses for arsenic.
Approximately 90 percent of industrial arsenic in the U.S. is currently used as a wood preservative, but arsenic is also used in paints, dyes, metals, drugs, soaps, and semi-conductors. Agricultural applications, mining, and smelting also contribute to arsenic releases in the environment.

What are arsenic’s health effects?
Some people who drink water containingarsenic well in excess of the MCL for many years could experience skin damage or problems with their circulatory system, and may have an increased risk of getting cancer.

This health effects language is not intended to catalog all possible health effects for arsenic. Rather, it is intended to inform consumers of some of the possible health effects associated with epichlorohydrin in drinking water when the rule was finalized.  More info…
