Mr. Randy Schrock 55 Faranhyll Road Glenwood Springs, CO 81601 maiI@rschrock.corn Via Email RE: Schrock — Well Water Quality Analysis Dear Randy: August 2, 2018 At your request, Resource Engineering, Inc. (RESOURCE) analyzed the water quality of an existing well (a/k/a Schrock Well; Permit No. 281229) for your Garfield County Land Use Application. This letter report presents the technical analysis of the water quality for the Schrock Well located at 55 Faranhyll Road, Glenwood Springs, Colorado. More specifically, the Schrock Well is located in the NW1/4, SW1/4, Section 10, Township 7 South, Range 89 West of the 6th P.M. at a distance of 2,373 feet from the South section line and 348 feet from the West section line. WATER QUALITY A water sample for the existing well was obtained by RESOURCE on July 10, 2018. The sample was shipped by overnight delivery under proper chain of custody to Colorado Analytical Laboratories, Inc. (results attached). In accordance with the criteria established by the Garfield County Land Use and Development Code, the well was tested for inorganic compounds including metals, coliform, alkalinity, corrosivity, hardness, pH, total dissolved solids, and radionuclides. The attached results indicate that the well water meets the basic EPA primary and secondary drinking water standards with the following exceptions: 1. The presence of Total Coliform. The EPA primary drinking water standard for Total Coliform is zero for 100 mL of water. 2. Manganese level of 0.0655 mg/L. The National Secondary Drinking Water Regulation (nonenforceable) is 0.05 mg/L. We also note that the water is considered very hard (>200 mg/L as CaCO3). This requires softening for household or commercial use. The well water hardness is 223.8 mg/L as CaCO3. Hard water can cause scale to build up in boilers, water heaters, and on water fixtures, and lessen effectiveness of soaps. Hardness is typically treated if greater than 200.0 mg/L. Each of the exceeded National primary and secondary water quality parameters is further discussed below. Total Coliform Coliform bacteria include a large group and many types of bacteria that naturally occur throughout the environment and are common in both soil and surface water. Most types of coliform bacteria are harmless to humans, but some can cause mild illness and even fewer can lead to waterborne disease. The presence of coliform indicates that a contamination pathway exists between a source of bacteria (surface water, animal waste, septic system, etc.) and the water supply. Consulting Engineers and Hydrologists 909 Colorado Avenue Glenwood Springs, CO 81 801 ' (970) 945-6777 Fax (9701945-1137 Randy Schrock Page 2 August 2, 2018 Coliform bacteria is much more common in springs and in shallow wells compared to deeper wells as the bacteria is filtered out by soil and rock as surface water infiltrates the ground. The presence of Total Coliform indicates that the groundwater supply is under the influence of surface water. Total Coliform can be treated with filtration. Ultrafiltration (average pore size of 0.01 micron) or higher level of treatment is required is typically required. Disinfection (i.e. chlorine or ultraviolet light) will also treat bacteria. Shock chlorination of the well is also often utilized for treatment; however, contamination could occur again over time. Manganese Manganese is an essential trace element for microorganisms, plants, and animals. Health problems is humans may arise from deficient and excessive intake. An average dietary intake typically arranges from 2 to 10 mg/day. The EPA has a nonenforceable secondary drinking water standard of 0.05 mg/L. Microfiltration or higher is effective in treating manganese. CONCLUSION The laboratory results for the water quality analysis indicate that the water meets most primary and secondary drinking water standards. Exceptions include Total Coliform and secondary standard for manganese. In addition, the water was found to be very hard. Total Coliform can be treated with disinfection (i.e. chlorination or ultraviolet Tight) or ultrafiltration (average pore size of 0.01 micron) to meet the primary drinking water standard. The secondary water standards and hardness are not health threatening and are nonenforceable. Therefore, with disinfection or ultrafiltration, the water quality is suitable for domestic use (including irrigation). Additional water treatment as further explained below is recommended depending on personal taste, odor, and aesthetics. It is our understanding that the existing house on the property has a Culligan water treatment system that includes water softening and filtration. RESOURCE recommends that a similar water treatment system be installed at any future dwelling that utilizes this well as a source of supply. Higher levels of filtration may be needed depending on taste and Total Dissolved Solids (TDS) concentrations; therefore, testing the water quality post treatment after the existing system will provide useful information to determine if any additional treatment is necessary. Please call if you have any questions or need additional information. Sincerely, RESOURCE ENGINEERING, INC. Eric F.
