Attached are the most recent nitrate results for your water. Remember we took this sample upstream of your water filter. I recommend you have your water tested downstream of the filter to ensure it is working properly. Nitrate concentration was reduced due to the pressure grouting Nitrate concentration hasn’t increased since 2019 Attached is a nitrate fact sheet we issue with COSAs when nitrate concentration exceeds 10 mg/L.

Nitrate concentration was 13.8 mg/L. results attached. May 2019, COSA action states that nitrate sampling was done after Discovery Drilling pressure grouted the well. Nitrates were 13.8 mg/L after the pressure grouting, SWL 34’ May 2019, a camera was run down the well to 50’ depth. No cracks or holes were present. Moisture was not present at the pitless. May 2019 Discovery drilling advanced probes to 33’ and grouted from 33’ to 8’ Apr 2019 The nitrate level on 4/30/2019, prior to pressure grouting, was 16.5 mg/L according to Garness Engineering. Dec 2006 nitrate 7.8 mg/L Nov 2006 nitrate 10.1 mg/L June 2003 well drilled to a depth of 203’, cased to 203’, casing perforated 50’ to 60’, wet clay found from 32’ – 58’, another strata of wet clay was found at 150’ – 155’, another water strata was present from 195’ – 203’, SWL 28’. Here is an example where the well log states that there are multiple water bearing strata that this well penetrates. The casing is only perforated in one of those strata, (highest strata).

ENGINEER’S COMMENTS G. CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm FIRST WATER CONSULTING Phone 907-350-9566 Engineer’s Printed Name CURTIS HUFFMAN, PE Date 8/22/24 Comments: This investigation was completed in compliance with MOA guidelines, regulations, and best industry practices / methods. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 8/22/24 MUNICIPALITY ANCHORAGE DEVELOPMENT SERVICES DEPARTMENT 907-343-7904 On -Site Water and Wastewater Section -ax: 343-7997 www.muni.org/onsite Nitrate Advisory Certificate of On -Site Systems Approval # OSC241343 Subdivision: Rockhill, Block: 4, Lot: 6 A water sample revealed a nitrate concentration of 12.1 milligrams per liter (mg/Q. 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.

QUIK-GROUT grouting and plugging material does not contain any polymers. Applications/Functions • Can seal or grout plastic and steel casings • Can seal downhole instrumentation in test and observation holes • Can plug abandoned boreholes and earthen cavities • Not recommended for use as a cement additive Advantages • Easy-to-use one sack grout • Dust-free mixing • Can be mixed and pumped using conventional rig equipment • Rehydratable • No heat of hydration • Can develop a 20%active solids slurry weighing 9.4 lb/gal (1.13 glcm3) with hydrostatic gradient of 0.489 psi/ft(11.1 kPa/meter) • Can create a low permeability seal to prevent entry of contaminants from the surface • Can develop a permanent,flexible seal to prevent commingling between aquifers • NSF/ANSI Standard 60 certified • Typical Properties • Appearance Beige to tan granules • Specific gravity 2.6 • pH (8% slurry) 8.2 • Electrical Resistivity 0.98 ohm-meter • Yield Volume 26.3 gallons per 50-lb sack 99.5 liters per 23-kg sack • Permeability(in fresh water) 2.5 x 10"8 cm/sec Recommended For maximum results, pre-treat make-up water with Soda Ash to less than Treatment or equal to 100 mg/I total hardness and to a pH range of 8.5—9.5. The recommended mixing rate is one 50-lb (23-kg) sack of QUIK-GROUT grouting and plugging material per 24 gallons(91 liters) of fresh water to create a 20%active solids by weight grout with a density of 9.4 lb/gal or 1.13 g/cm3.

Purchaser assumes all risk of use and handling of this product.This product will be replaced if defective in manufacture or packaging cr if damaged Except for Such replacement.seller is not liable for any damages caused by this product or its use The statements and recommendations made herein are believed to be accurate. No guarantee of their accuracy is made however. Recommended Mixing Do not over mix and do not use a centrifugal pump. Procedure 1. Using a mixing device, blend one sack of QUIK-GROUTh grouting and plugging material into 24 gallons (91 liters) of fresh water. Rate of addition should be about 20 to 30 seconds per 50-lb(23-kg) bag. Note:The resulting slurry should have an oatmeal consistency containing unyielded or partially yielded bentonite. 2. Pump slurry through tremie pipe into hole without delay. Grout slurry should be pumped through tremie pipe from bottom of interval to surface to ensure effective displacement. Maintain submergence of tremie pipe a minimum of 10-feet within grout column for uniform displacement. Additional Information • The grouting material and method selected will depend upon the specific subsurface environment including all prevailing geological and hydrological factors and any existing regulatory requirements. The grouting process may not be complete until the grout is static at the desired level. • The use of bentonite may not be appropriate in environments where the formation water chemistry has a total hardness greater than 500 parts per million and/or a chloride content of greater than 1500 parts per million. • If questions arise regarding subsurface environments it is always best to consult your local Baroid IDP representative to determine if the Baroid product of choice is appropriate for the given conditions. Packaging QUIK-GROUT grouting and plugging material is packaged in 50-lb(23-kg) multiwall paper bags, containing 0.7 ft3(0.02 m3). Availability QUIK-GROUT grouting and plugging material can be purchased through any Baroid Industrial Drilling Products Retailer.
