Robert Bell & Associates 801 W. Fireweed Lane Anchorage, AK 99501 Dear Tobin: RE: Testhole Report for On-site Systems - Eagle River Development Enclosed are the results of our investigation of 30 testholes on 26 lots for the proposed subdivision. Testholes were logged on April 22"a & 23ra of this year with percolation testing occurring through the following week. Water monitoring was conducted on May 15th, during the seasonal high water period. Existing Conditions: The area is gently sloping and densely covered with birch, spruce, cottonwood, aspen and some willow. Snow was encountered at various depths but normally less than 12" with open areas prevalent throughout the site. There was no runoff observed and the snow was melting indicating that the majority of the moisture was being absorbed into the underlying soil strata. This was confirmed during our investigation as we found moist soil conditions in the majority of the testholes. Procedures: Testholes were located and staked by F.R. Bell & Associates, prior to excavation. Testholes were excavated utilizing a Link-Belt excavator operated by CCC Construction. Two of the testholes were relocated due to shallow ground water encountered during excavation. Monitoring tubes, comprised of 4" perforated F810 pipe were installed in all testholes. Percolation holes were presoaked and testing was conducted in accordance with the falling head percolation testing procedures with the following exceptions. Some testholes had percolation rates less than i minute/inch, which required a modified approach to insure that these rates provided consistent readings. Results: On the 26 lots we excavated 32 testholes and conducted 30 percolation tests. Two testholes were located in low areas. Ground water was found close to the surface in Testhole Report for On-site Systems - Eagle River Development May 2?, 1999 Page 2 of 2 these locations and they were abandoned with new testholes excavated in higher areas of the lot. Minor frost was encountered in the upper layers of the soil but it was not significant enough to log. As we discussed previously, only one lot (Lot 13) did not have a passing percolation test. Although we feel that the results of the testing was an anomaly, discussions with DHHS indicate that a new testhole and percolation test will be required on this lot. A few testholes had seeps that were felt to be seasonal due to breakup conditions at the time of testing and this was followed up with water monitoring on May 15~h which confirmed this analysis. No testholes had ground water at levels that would preclude construction of a conventional on-site septic system. If after your review you have any questions regarding the results of our investigation please contact me at 696-6111/FAX 696-8111, at your convenience. Thank you for the opportunity to serve you and we look forward to working with you in the future. Respectfully submitted,...~ cc: file I[~[~D_~ ENG~NEEPdNC 20441 PTARMIGAN BLVD.

Fireweed Lane Anchorage, AK 99501 Dear Tobin: RE: Testhole Report for Lot 13 - Eagle River Development Enclosed are the results of our investigation of Lot 13 for the referenced development. As discussed, due to the previous percolation rate for this lot it was necessary to retest it to verify the suitability for construction of on-site septic systems. Due to the proximity of our new testhole to the original testhole we did not install another monitoring tube, however we did monitor water during the periods indicated in the original testhole. The existing conditions and procedures identified in our May letter remain the same. Results: We conducted two percolation tests in separate soils stratum. The results of that testing indicate that the soils stratums tested will percolate at 16 and 32 minutes per inch. No water was encountered during excavation. Based on the results of this testing this lot meets and exceeds the minimum requirements for on-site septic systems.

We initially assumed that drawdown reported on the well logs was from a one- hour well test and we used that value to calculate the transmissivity from each well. I talked to one of the Eagle River drillers who said that our assumption is invalid, that pumping or testing time is unlmown for all of the wells. Lacking a valid pump test, I looked at each well log for the unconsolidated aquifer. I found uine logs that described a gravel aquifer, one log describing a sand aquifer, and twelve logs that show a gravel-sand aquifer. Well yields range from 2 to 500 gallons per minute, with 50% of the yields greater than 15 gpm. The lowest well yield was 2 gpm. This data allows us to use standard tables (Freeze & Cherry, 1979, Table 2.2) to estimate hydraulic conductivity for a clean sandy gravel aquifer. Hydraulic conductivity for this type aquifer ranges from 10,000 to 1,000,000 gallons per day per square foot. Assuming an aquifer thickness of 10 feet, transmissivities would range from 100,000 to 10,000,000 gallons per day per foot (GPD/fr) for a gravel aquifer. Remodeling the unconsolidated aquifer shows that expected drawdown along the bedrock interface is likely to be in the range of 0.01 to 1 feet. This assumes a municipal use xvell pumping 60 gpm continuously for 10 years. Single lot wells would likely produce less impact on the unconsolidated aquifer. We also plolIed the potentiometric surface (ground water elevations). This surface, attached, shows that areas with a ground water elevation below 500 feet are likely recharging from the same unconsolidated aquifer as the one found in the proposed Mclntyre Subdivision. The map shows that many wells have water elevations above that of the unconsolidated aquifer, suggesting that the recharge is uot from the unconsolidated aquifer. Again, this data is of limited use since water levels were recorded over many years. Our conclusions from this new evaluation are: 1. Ground water impacts from pumping in the proposed Mclntyre Subdivision will likely be insignificant to the surrounding water users (less than 1-foot drawdown at the bedrock interface). 2. Many of the wells surrounding the Melntyre Subdivision are in bedrock with static water levels above the unconsolidated aquifer in the Mclntyre Subdivision. This suggests that the bedrock aquifers are not hydraulically connected (except where shown on the attached map). Thus, pumping fi'om the Mclntyre subdivision would likely have no effect on most of the surrounding wells. 3. An aquifer test is required to confirm and refine our estimates of transmissivity in the unconsolidated aquifer. However, without such a test, our interpretation of the well logs suggest that, more likely than not, no significant ground water impact will occur to the bedrock aquifer by pumping 60 gpm from the unconsolidated aquifer in the proposed Mclntyre Subdivision.

We initially assumed that drawdown reported on the well logs was from a one- hour well test and we used that value to calculate the transmissivity from each well. I talked to one of the Eagle River drillers who said that our assumption is invalid, that pumping or testing time is unknown for all of the wells. Lacking a valid pump test, I looked at each well log for the unconsolidated aquifer. I found nine logs that described a gravel aquifer, one log describing a sand aquifer, and twelve logs that show a gravel-sand aquifer. Well yields range from 2 to 500 gallons per minute, with 50% of the yields greater than 15 gpm. The lowest well yield was 2 gpm. This data allows us to use standard tables (Freeze & Cherry, 1979, Table 2.2) to estimate hydraulic conductivity for a clean sandy gravel aquifer. Hydraulic conductivity for this type aquifer ranges from 10,000 to 1,000,000 gallons per day per square foot. Assuming an aquifer thickness of 10 feet, transmissivities would range from 100,000 to 10,000,000 gallons per day per foot (GPD/ft) for a gravel aquifer. Remodeling the unconsolidated aquifer shows that expected drawdown along the bedrock interface is likely to be in the range of 0.01 to 1 feet. This assumes a municipal use well pumping 60 gpm continuously for 10 years. Single lot wells would likely produce less impact on the unconsolidated aquifer. We also plotted the potentiometric surface (ground water elevations). This surface, attached, shows that areas with a ground water elevation below 500 feet are likely recharging from the same unconsolidated aquifer as the one found in the proposed Mclntyre Subdivision. The map shows that many wells have water elevations above that of the unconsolidated aquifer, suggesting that the recharge is not from the unconsolidated aquifer. Again, this data is of limited use since water levels were recorded over many years. Our conclusions from this new evaluation are: 1. Ground water impacts from pumping in the proposed Mclntyre Subdivision will likely be insignificant to the surrounding water users (less than 1-foot drawdown at the bedrock interface). 2. Many of the wells surrounding the Mclntyre Subdivision are in bedrock with static water levels above the unconsolidated aquifer in the Mclntyre Subdivision. This suggests that the bedrock aquifers are not hydraulically connected (except where shown on the attached map). Thus, pumping from the Mclntyre subdivision would likely have no effect on most of the surrounding wells. 3. An aquifer test is required to confirm and refine our estimates of transmissivity in the unconsolidated aquifer. However, without such a test, our interpretation of the well logs suggest that, more likely than not, no significant ground water impact will occur to the bedrock aquifer by pumping 60 gpm from the unconsolidated aquifer in the proposed Mclntyre Subdivision. I hope this letter provides clarification to our report. Please call if we can provide further information. Sincerely, Dan Young, President, Professional Hydrogeologist TERP,~\SAT INC. 12/24/98 07:4?
