(RESOURCE) analyzed the water quality of an existing well (Rem -lit Na_ 59504-F) at your property near Glenwood Springs, Colorado located at 4006 County Road 115 in Garfield County. This letter report presents the technical analysis of the water quality_ WATER QuAurY Water samples from the well were obtained by RESOURCE on July 18, 2016 during a well pump test. The sample was shipped by overnight delivery under proper chain of custody to Colorado Analytical Laboratories, Inc. (results attached).' In aCoOrdahce 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, ply, total dissolved solids, and radionuclides. The attached results indicate that the well water meets the basic EPA primary and seoondary drinking water standards with the following exceptions: 1. The presence of Total Coliform. The EPA primary drinking water standard tot Total Coliform is zero for 100 mL of water. 2. Manganese level of 01652 mg/L. The National Secondary Drinking Water Regulation (nonenforc eable) is 0.05 mgfL, We also note that the water is considered very hard (>200 rng/L as CaCO3). This requires softening for household or commercial use_ The well water hardness is 210.9 rrlg/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 Co[rforrn bacteria include a Targe group and many types of bacteria that naturally occur throughout the environment and are common in both soil and surface water. Most types of Colorado Analytical Laboratories subsequently sent sampled water Hazen research, Inc. for the analysis of Cross Alpha and Gross Beta radionuclides.

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_ Coliform bacteria is much more common in springs and in shallow wells compared to deeper wells as the bacteria is filtered out by sail 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 pare 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 rnay arise from deficient and excessive intake. An average dietary intake typically arranges from 2 to 10 mg stay_ 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. The well water quality is suitable for domestic uses and irrigation with additional treatment such as microfiltration, water softening, and disinfection. it is our understanding that water from the existing well enters a water softener and disinfection treatment system prior to being stored in a pressure tank. From the pressure tank, water is then distributed to both the main residence and the accessory dwelling unit (ADU) Located in the barn. The main residence also includes microfiltration and has a reverse osmosis system under the kitchen sink. RESOURCE recommends that the ADU also include microfiltration for the removal of manganese_ However, this is not required as Manganese is a nonenforceable secondary drinking water standard.
