Box 3-3772 ECB Anchorage, Alaska 99501 Subject: Subsurface Investigation for Feasibility for On-Site Sewage Disposal Systems - Lots 2 and 3B, Block 1; and Lots 10 and 11, Block 2., Silvercrest Subdivision Dear Mr. Stephens: As requested we performed a'subsurface investigation on the four above referenced lots to determine their suitability for placement for on-site sewage disposal systems. Three test holes were placed on April 12 and 13, 1978. The holes were drilled by Denali Drilling, Inc. The test holes were logged and the drilling supervised by Mr. O. M. Hatch, senior technician/geologist with AlaskaTestlab. The holes are located on the adjacent figures #1 and #2. The test hole logs are included .as Table A. It may prove helpful in interpreting the data on the test hole logs to review the standard explanatory information contained on Sheets 1-3. Once the test holes were drilled, .they were cased with slotted plastic pipe. About a week later the test holes were checked for ground water intrusion into'the holes. None had occurred. All three of the test holes were dry. On May 8, 1978, the test holes were filled with water and left over night to saturate. A percolation test was then performed the next day, May 9, 1978, by refilling the holes and monitoring ~the rate at which the water fell in the holes at 10 minute intervals for a period of one hour. · he percolation rates based .on this testing are as follows: Lot 2, Block 1 -- 7~7 minutes/inch. Lot 3B, Block 1 -- 3.1 minutes/inch. Lots 10 and 11, Block 2 -- 3.3 minutes/inch. Mr. Mike Stephens May 16, 19'78 Page 2 We would caution the use of a percolation rate as fast as 3.1 minutes/inch in Lot 3B, Block 1 and 3.3 minutes/inch in Lots 10 and 11, Block 2. It is our experience that due to the clogging action of sewage effluent, a more conserva- tive design value should likely be used in silty sands and silts. We would recommend a design value of 5 minutes/inch for these lots. We hope this is sufficient for your present needs. If we can be of further service or offer any clarification of any data presented here, please do not hesitate to contact us. Very sincerely, .AT.ASKA TESTLAB Robert C.

Garness Date: e' 13b Zr In conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including but not limited to, soil conditions, groundwater levels (that may fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation. Reliance upon the information provided in this report by any other person or party (including subsequent property purchasers) is not authorized, nor will it confer any legal right whatsoever. 6.

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. 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. Madmg Address P O Box 196650 *Anchora"6A64951946650*www muni 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.
