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. �... Mailing address P O Box 196650 *Anchorage, Alaska 99519 6650 *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.

Health & Human Services Attn: Manny Escobedo Subject: Well & Septic System Inspection at Lot 8, Bk 5, Mountain Park Estates #2 S/D. To whom it may concern: Per the request of the real estate agent, Manny Escobedo (Jack White Real Estate), we performed adequacy tests on the subject well and septic system. The results of the field investigation and adequacy tests are summarized as follows: A. WELL: The static water level on 1/5/99 was 176 feet below the top of the casing (BTC). Water was pumped t?om the well at a rate of 5.22 gpm for a total of 115 minutes (600 gallons). Within the first 20 minutes of pumping, the level in the casing dropped 9 feet (187 feet BTC), and remained at essentially that level throughout the rest of the test. In short, the recharge rate equaled the pumping rate (5.22 gpm). Based upon this data it was determined that the capacity of the well exceeds the Municipal requirements for a 3 bedroom house (450 gallons per day). The well was originally drilled in April of 1981 by Ken's Company, and deepened in January of 1997 by Alpine Drilling. A copy of the most recent well log is attached. B. SEPTIC SYSTEM ADEQUACY TEST: The drainfield is a trench type system that was installed in April of 1981, making it almost 18 years old. According to the M.O.A documents, the trench is 3 feet wide, 85 feet long, and has an effective depth of 3 feet. Based upon our field measurements, the sump extends approximately 39 inches below the drainpipe invert. Prior to the start of the test there was 27 inches of liquid in the north monitoring tube (MT). The south monitoring tube had not been located prior to performing the test. The septic tank was pumped the day before the test was performed. Over a period of 115 minutes, 600 gallons was introduced into the north sump. The first 189 gallons caused the level to rise 10 inches (37 inches in sump), and the next 411 gallons only caused a rise of 4 inches (41 inches in sump. Drainpipe approximately 1/2 full). Twenty-four hours later the liquid level in the sump had dropped 10 inches, indicating that about 525 gallons had been absorbed (411 + 6(18.9) = 524.4 gallons). Based upon this data, it was determined that the absorption capacity of the drainfield meet the MOA requirements for a 3 bedroom house (450 gallons per day); however, it should be noted that the system had to filled to almost 100% of its capacity in order to achieve this absorption rate. ~/~. REPAIRS: Prior to applying for a municipal health certificate the following repairs will need to be done: · Locate the sump at the south end of the trench, and have it extended above grade. iclC Repair the separated pipe joints on the north sa ,mp. Recommended contractors to do the repairs: Carl s Excavating (Carl Elsenbast, 346-3568), A+ Home Services (Mike Blakeslee, 345-1890), G&G Equipment (Gary Skaggs, 346-3338). D.
