Monument performed preliminary research into the cause of the reduced well production through an analytical laboratory and consulting firm, Water Systems Engineering, Inc (WSE) who provided recommended cleaning procedures to recover some well capacity. The well report from WSE is available as Appendix B to this RFP. Well #7 Construction and Background Monument’s Well #7 was drilled and constructed in 2009 using reverse mud rotary drilling. The borehole was 20” diameter and drilled to a depth of 1,800 feet below ground surface (bgs). The well was completed to a depth of 1,766 feet bgs. Due to alternating lithologic units of fine sands, shales, and clays, 12 discrete screen zones totaling 245 feet ranging from 10 to 45 feet in length each were placed at depths of 1,273 feet bgs and deeper, with blank casing installed from 1,273 feet bgs to the ground surface. The well construction materials consist of 10 3/4” diameter steel blank casing and 10 3/4” diameter 0.040” slot stainless steel screen. The well completion report is attached in Appendix A. A photo of the well head (right) with the cap removed shows an approximate opening of 12”.Recently, a 37% loss of production has been observed in the well. A Complete Well Profile analysis was prepared by WSE to assess the loss of production of the well. A groundwater quality sampling event on August 30, 2022, including sampling both the well casing and the groundwater in the aquifer, showed heavy visible bacterial activity, low debris, moderate plant particulate matter, moderate iron oxide, and moderate iron oxide entrained biomass with very low numbers of Gallionella, naturally occurring iron-oxidizing chemo lithotrophic bacteria that have been identified in a variety of aquatic habitats. The analysis found a mildly corrosive groundwater environment low in dissolved mineral content with limited concern for carbonate or sulfate scale formation although oxides are a possibility. The biological content was large and highly diverse with iron oxidizing bacteria being the primary concern. A possible contributing factor is the corrosive nature of the groundwater attacking the metallic well structure as well as leaching iron out of the naturally occurring formation material resulting in iron being available as an energy source promoting bacterial growth (WSE, 2022). ---PAGE BREAK--- 5 The WSE report is included in Appendix B. No known depth discrete testing has been done on the well to define varying water quality or visible bacterial activity or debris build-up within each of the screen zones. Quantities of cleaning chemical identified in the WSE report are to serve as the basis for the bid: Phosphoric Acid 75 Gal Biodispersant 50 Gal Potable water for blending (rehabilitation) 1,000 Gal Sodium Hypochlorite 13 Gal Chlorine enhancer 6 Gal The Town of Monument will provide water for blending. Water is available at a bulk fill station approximately 0.4 miles east of the project site.

The Complete Well Profile utilizes a series of inorganic chemical and microbiological tests to identify fouling and corrosion issues with potential impacts on the operation of the sampled well. The tests include a number of inorganic chemical parameters such as pH, total dissolved solids/conductivity, hardness, alkalinity, oxidation reduction potential (ORP), bicarbonate, carbonates, silica, sodium, potassium, chloride, iron, manganese, phosphate, nitrate, sulfate, and total organic carbon (TOC). Biological assessment is designed to quantify the total bacterial population, identify two dominant populations of bacteria, assess anaerobic conditions, and identify the presence of iron related bacteria and sulfate reducing organisms. Also included are tests for Adenosine triphosphate (ATP), heterotrophic plate count (HPC), and a microscopic evaluation; and in potable systems, total coliform and E. coli coliform presence/absence. Testing Procedures: All laboratory testing procedures are performed according to the guidelines set forth in Standard Methods for the Examination of Water and Wastewater as established by the American Public Health Association (APHA), American Water Works Association (AWWA), and Water Environment Federation (WEF). Corrosion analyses are performed in accordance with the guidelines as set forth by the National Association of Corrosion Engineers (NACE). In general, these methods are approved by both the Environmental Protection Agency (EPA) and AWWA for the reporting of water and/or wastewater data. Sample collection and shipment is the responsibility of the customer, performed according to protocol and procedures defined by the laboratory in advance of the sampling event with regards to the specific project and nature of the problem.

[PHONE REDACTED] http://www.h2osystems.com 22535.w.pw.p.Monument,CO.Well7 Page 3 of 6 Biological Analysis: Microscopic Evaluation: Casing: Heavy visible bacterial activity, low debris, moderate plant particulate matter, moderate iron oxide, moderate iron oxide entrained biomass with very low numbers of Gallionella. Aquifer: Heavy visible bacterial activity, heavy debris, low plant particulate matter, moderate iron oxide, moderate iron oxide entrained biomass with very low numbers of Gallionella. Observations and Interpretations: When received in the lab both the casing sample and the aquifer sample were light orange in color with a small amount of brown sediment which was identified as iron oxide. The samples displayed low alkalinity and total hardness being entirely carbonate hardness. Total dissolved solids (TDS) were within an acceptable range for a potable water supply. The samples displayed a neutral pH. The oxidation-reduction potential (ORP), at a positive value of approximately 200 millivolts represents an oxidizing environment with a tendency for metal oxide deposition. The Langelier Saturation Index (LSI), which is a calculation of the amount of dissolved calcium carbonate in the water and an indication of the potential for calcium carbonate scale deposition, was negative, implying an under balanced condition. Since the calcium carbonate concentration is not at the saturation point there is a reduced concern for carbonate scale deposition taking place. Carbonate scale formation is unrelated to other forms of scale formation such as sulfates and oxides. A negative LSI can also be an indication of potentially corrosive groundwater conditions.

[PHONE REDACTED] http://www.h2osystems.com 22535.w.pw.p.Monument,CO.Well7 Page 4 of 6 Chemicals found to be present at concentrations above an ideal groundwater concentration were limited to manganese, potassium, and resuspended iron. Resuspended iron is iron that has been concentrated by biological as well as chemical means and as such is an indicator of the presence and population level of iron related bacteria. Adenosine triphosphate (ATP) a component of all living cells were below levels of concern in both samples initially, but the concentration in the casing sample increased dramatically from 63,000 cells per milliliter to 286,000 after a 24-hour incubation period, an indication of the organism’s ability to reproduce under favorable conditions. ATP cell counts for a typical well not experiencing biofouling are generally in the range of 20,000 to 70,000 cells per milliliter. Cell counts above 100,000 cells per milliliter are an indication of excessive bacterial growth with a potential for bacterial congestion and biofouling. Anaerobic growth as a percent of the total bacterial population was below 10% in both samples which is considered a typical level for a well not experiencing elevated anaerobic growth. Sulfate reducing bacteria were not detected. Microbial growth was limited on the culture plates although it may actually be higher since over 90% of all bacterial species do not grow under laboratory conditions. The dominant bacterial species present on the culture plates were species of Acidovorax. Acidovorax delafieldii is an aerobic, gram negative, soil bacterium. The bacteria’s presence in the sample is likely derived with the area of recharge for the well and aquifer, reflecting interaction with the upper soil horizons. The test to determine the presence or absence of total coliform bacteria was negative. This includes E. coli specific coliforms. The microscopic evaluation of the casing sample found a heavy level of visible bacterial activity. There was also a moderate amount of iron oxide and iron oxide entrained biofilm. There was a very low population of Gallionella. Gallionella are naturally occurring, iron-oxidizing chemolithotrophic bacteria that have been identified in a variety of different aquatic habitats, including groundwater. They are a generally aerobic group of bacteria that utilize iron as an energy source and secrete an iron-oxy-hydroxide byproduct. This secretion is often responsible for accumulations of iron oxide in wells and piping systems. There was also a moderate amount of plant particulate matter noted under the microscope. The aquifer sample had a heavy amount of visible bacterial activity with moderate iron oxide and biofilm, Gallionella was noted in low numbers. There was a low amount of plant particulate matter and a heavy amount of matter. Conclusions and Recommendations: The complete profile analysis found a mildly corrosive groundwater environment low in dissolved mineral content with limited concern for carbonate or sulfate scale formation although oxides are a possibility. The biological content was large and highly diverse with iron oxidizing bacteria the primary concern. This would be consistent with the levels of iron oxide and iron oxide entrained biofilm noted under the microscope. A possible contributing factor is the corrosive nature of the groundwater attacking the metallic well structure as well as leaching iron out of the naturally occurring formation material resulting in iron being available as an energy source promoting bacterial growth. Treating the wells following the guidelines presented below should help reduce the bacterial load and restore at least part of the 37% drop in production. The process should begin with ---PAGE BREAK--- Water Systems Engineering, Inc. [PHONE REDACTED] http://www.h2osystems.com 22535.w.pw.p.Monument,CO.Well7 Page 5 of 6 pulling the pump and mechanically scrubbing the interior of the well using a surge block or brush. This will help remove loose scale, rust deposits, and biofilm which can provide a protective environment for microorganisms. Once the entire column has been scoured, bail or pump the disrupted material and any fill from the well, starting at the bottom. Fully evacuate the well until the discharge becomes visibly clear. Chemical treatment should begin by placing a solution of 7% phosphoric acid combined with 2% dispersion polymer such as Layne Christensen’s QC-21 or Johnson Screen’s NW-310 biodispersant equal to 1.5 times the standing well volume into the screen section and aggressively swabbing or surging it into the screened zones for approximately 8 hours. The recommended biodispersant is NSF approved for use in potable wells and recommended to enhance the activity of the acid in cleaning biomass and improving the efficiency of the acid in attacking mineral scale. The acid and biodispersant solution will also aid in breaking down the biofilm that surrounds and protects the organisms, allowing for better penetration of the disinfection solution. The use of phosphoric acid is recommended for the cleaning, over other more aggressive acids for several reasons, in addition to being a “chemically” cleaner product, phosphoric acid is safer for the crew to use and reduces the impacts on the well structure. The use of more aggressive acids is not advised as they are inclined to cause chloride attack of the steel well components, increasing the chance of damage and releasing additional iron into the already aggressive groundwater. Similarly, the use of hydrogen peroxide, a very reactive oxidizing chemistry is not recommended as it could aggravate areas of corrosion within the well. During surging, monitor the pH and maintain a pH of 3 or less. Purge the well until visual turbidity is absent, the pH has returned to normal background levels, and the conductivity has returned to a normal, pre-treatment range. Once the well has been effectively purged of all residue and is pumping clear of visible turbidity, disinfection should be carried out utilizing a pH adjusted chlorination at a 250-ppm chlorine level with a targeted pH range of 6.5 to 7.0. The treatment volume of the disinfection solution should be equivalent to 3 times the treatment zone volume and evenly distributed throughout the producing zones. This larger volume is meant to flood the borehole with the disinfection solution to increase the effective treatment zone. Utilization of a chlorine enhancing chemistry such as Layne’s Oximate or Johnson’s NW-410 chlorine enhancer for pH control is strongly advised to improve disinfection. The disinfection solution should be surged into the well for approximately 6 hours. Monitor the chlorine level during disinfection and add additional chlorine to maintain at least a 100-ppm chlorine level during disinfection. Leave the solution in the well over night and surge the following morning for 4 hours while maintaining a 100-ppm chlorine concentration before pumping off. For acid treatments, mix the chemicals in this order: water, acid, biodispersant. Mix If during acid treatment, the pH rises to a level above 3.0, add additional acid and water in the ratio of 2 gallons acid and 1 gallon of water. No additional dispersant should be needed. For the chlorine treatment, mix the chemicals in this order: water, chlorine enhancer, check the pH (below 5.5 add chlorine, above 7 add chlorine enhancer). Mix During disinfection, if the chlorine residual has dropped to below 100 ppm, add additional sodium hypochlorite in increments of 0.12 gallon to raise it to that level. The following quantities are necessary for each step of the recommended treatment process to treat the well below the 1,250-foot level which includes each of the 12 individual screen sections and the 40-foot sump; ---PAGE BREAK--- Water Systems Engineering, Inc.

It is recommended that the well be put into operation as soon as possible and pumped on a regular schedule to inhibit the regrowth of microorganisms. Even though cleaning and disinfection will reduce the bacterial population, it is not possible to kill-off all the organisms and regrowth is probable.
