Description - The well and septic system are existing and were installed in approximately 1977. Documentation of the septic system is on file with MOA. The documentation reports that the well is 64 feet deep but no well log was found. The well and septic serve an existing 3 -bedroom single family residence, with a design wastewater flotiv of 450 gallons per day. Site Topography - An as -built survey and topographic map are attached. The well, house, and septic tank sit at approximately the same elevation, on a bench which parallels the Old Glenn Highway. To the East -Southeast, the grade drops steeply by approximately 10 feet, and then levels off. The septic soil absorption trench is located on this lower level. Soils and Aquifer - Documentation for this and nearby properties indicates that soils are clean sandy gravel (GP - GW) to a depth of approximately 6 feet, underlain by silty sandy gravel (GM). The nearest available well log found (copy attached) is for L8 Stockhausen, immediately to the west of the subject property. This log indicates a layer of hardpan from 13 to 69 feet, which can be considered a confining layer protecting the aquifer. This is supported by the fact that water was encountered at 74 feet, but the static water level was reported at 20 feet, indicating a confined artesian aquifer. Conclusion and Recommendation - Considering that the existing well and septic system have been in operation for more than 40 years with no reported adverse impact to the well, and based upon the topography, soil and aquifer data, it is my opinion that a waiver allowing the existing separation distance is justified, and poses a. minimal to negligible risk. _®A_ - Please call or email if you have any questions or need additional information. Sincerely, Michael R. Erdman, PE 1Nlitrate Advisory Certificate of On -Site Systems Approval # OSC231125 Subdivision: Stockhausen, Block: , Lot: 10 N Ptn A water sample revealed a nitrate concentration of 6.2 milligrams per liter (mg/L). The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Since nitrates are known to slowly increase, we recommend you monitor the water quality. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On -Site Systems Approval. t > �� Mailing Address P O Box 196650 *Anchorage, Alaska ,99519 6650 * www rnun� org From Northern Testing Laboratories, Inc. Nitrate is a negatively charged compound of nitrogen and oxygen, which is very soluble in water. Nitrate is not readily filtered or otherwise removed in the soil and can pass rapidly into ground water wells. SOURCE: Nitrate is a major component of fertilizer and wastewater. Often the nitrate is in the form of ammonia or protein first, which through contact with oxygen and certain bacteria, converts to the oxidized form known as nitrate. Sources of nitrate from wastewater include urea, ammonia cleaners, food solids, and bacterial cells. It may also result from the breakdown of organic matter buried in the soil. TOXICITY: Nitrate is generally not toxic to adults or children over the age of two or three years, but is associated with a potentially fatal infant disease called methemoglobinemia. In the digestive system of young children, nitrate converts to nitrite, which can pass through the intestinal wall into the blood stream. There it combines with the hemoglobin and interferes with the ability of the blood to carry oxygen. For this reason, methemoglobinemia is referred to as "blue baby" disease. The EPA limits the concentration of nitrate in public drinking water supplies to 10 mg/L. The standard has been lowered from a previous level of 45 mg/L set by the US Public Health Service and the World Health Organization. TREATMENT: due to its solubility in water and negative ionic charge, filtration and other common home water treatment systems such as softening or iron filtration does not readily remove nitrate. The best method for limiting nitrate in well water is source control. This can include avoiding overdosing of fertilizer near the well and maintaining good separation distances between septic tank leach fields and the well. A special anion exchange filter that contains a media with a strong affinity for negatively charged ions in water, or by a reverse osmosis treatment system or distillation can remove nitrate. TESTING: Nitrate analysis is usually done by one of the several "wet chemical" methods using a spectrophotometer to read the final color endpoint. Specific ion electrodes also can be used to detect the activity of nitrate in water. This laboratory uses several different wet chemical methods approved under the public water supply laboratory certification program. They also have test kits available, which the laboratory uses to perform an inexpensive "screening test", and with which the homeowner can monitor the change in nitrate levels from their well. They recommend comparing the test kit results against a certified analysis from the lab occasionally to verify the accuracy of the kit. We recommend using a specially prepared bottle that has been rinsed in hydrochloric acid for collecting samples.
