Iron and manganese are the primary constituents of concern for these two sites, having been sampled above or near their secondary maximum contaminant levels. The City of Meridian asked WRT/Loprest Division to complete pilot studies at each site for water sources to remove these constituents in preparation for full-scale treatment. The pilot study was conducted to evaluate two filtration media types designed for iron and manganese removal. Well 26 is permitted to flow at 2,500 gpm, meanwhile Well 24 can flow at 1,800 gpm. Manganese levels are suspected to exceed the Idaho State secondary MCL value for drinking water of 0.05 mg/L in both raw waters. And dissolved iron is also present in both wells, but below its corresponding secondary MCL. In testing, measured iron levels in Well 24 were much less than originally reported. Concentrations of ammonia are low at both sites, though samples were analyzed for ammonia nitrogen to assess its effect on chlorination and residuals of free chlorine. Based off previous pilots conducted at Meridian well sites, WRT/Loprest Division selected two water treatment media systems for testing. Both medias are notable for their demonstrated effectiveness at removing iron and manganese. In line with these expectations, both media systems treated iron and manganese below secondary MCL values for both well sites. The project specifications require finished water from both wells be treated in accordance with USEPA and State of Idaho primary and secondary MCL standards for drinking water. State of Idaho secondary MCL values for iron and manganese are 0.3 mg/L total iron and 0.05 mg/L total manganese. The pilot test contaminant removal goals are treated water concentrations less than Idaho state drinking water standards while providing an ample chlorine residual post-treatment. Three (3) filter runs were conducted using both media types at each site to assess their contaminant removal effectiveness and their effects on ammonia reduction. Each of the filter runs had a service period of 8 hours followed by a backwash using treated water. Recommended chlorine doses for full oxidation and removal of iron and manganese are applied during the first filter run as determined via breakpoint chlorination tests conducted at each well. The second and third filter runs at each site help to demonstrate repeatable treatment results and further assess ammonia oxidation capability of both medias. Metal contaminant iron and manganese removal is the primary objective of the pilot studies. The filter columns are operated within the maximum industry standard hydraulic loading rate for iron and manganese removal and as recommended by the filter media manufacturers. Sodium hypochlorite(NaOCI)feeding rates are adjusted to maintain free chlorine residuals of at least 1 mg/L in the finished treated water. The first media type, media F1, is a mixed bed of Inversand's GreensandPluse granular media and anthracite coal with a hypochlorite reagent feed to generate available free chlorine oxidant as pretreatment. Pressure losses in F 1 systems gradually increased during Loprest, a division of WRT 901 W. 11611 Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 IUPREST Page 4 Well 26 filter runs and remained steady for Well 24 filter runs, never dropping more than 3.8 psi across all runs. F1 filter runs removed iron to nondetectable levels and manganese to 0.033 mg/L using field analytical methods. These systems were also able to reduce most if not all the ammonia present while conserving 85% of influent free chlorine, on average. The second media system tested,media F2,tradename Mang-Ox®,is a granular manganese oxide media. This media received the same hypochlorite pretreatment as the F 1 systems. On average, F2 systems usually had lower pressure losses than their F1 counterparts, and with comparable removal performances for all contaminants across all filter runs. The most notable difference between filter media being that F2 systems consumed more free chlorine presumably due to superior catalytic ammonia oxidation capability. Most field samples for ammonia nitrogen in raw water were measured below 0.1 mg/L, and reached maximums of 0.24 mg/L. Removal performance for ammonia was typically greater than 90%, save for a measured 8 5% ammonia removal for F1 systems at Well 26. Higher ammonia in Well 26 raw water corresponded to a higher breakpoint for sodium hypochlorite to generate a free chlorine residual above 1 mg/L wherein 2.6 mg/L is required compared to 1.9 mg/L in Well 24 raw water. Iron and manganese are treatable using either filter media, with similar performance between medias at both well sites. Backwashes at either site will likely be initiated on a basis of pressure loss at Well 26 and contaminant breakthrough for Well 24. With the test conditions encountered at these two (2)well water sources, an estimated theoretical solids loading capacity is achieved in 72 hrs. of filter service time for Well 26 water and more than approximately 7 days in Well 24 raw water before a filter cleaning backwash cycle is required. A maximum recommended service period before a backwash cleaning cycle is is 7 days for a full-scale system designed using either media type. Increasing hypochlorite dosing by roughly 20% above breakpoint was shown to reduce dissolved ammonia and effectively managing residual free chlorine in the filter effluent on both filter systems. 2.0 THE WRT/LOPREST FILTRATION SYSTEM AND STUDY OVERVIEW The WRT/Loprest system removes iron and manganese contaminants from drinking water in a downflow filtration media process using chemical oxidation and co-precipitation. Solid phase metal oxide contaminants are physically separated from the water stream, collected within a packed media bed and safely removed during a backwash operation. The backwash wastewater from the filter is directed to an on-site collection tank for disposal. The process has been designed for simplicity of operation minimal maintenance and reliable operation. The filtration system is similarly designed for versatility to adapt to the requirements of each well-specific treatment facility. Several media types have demonstrated effective catalytic oxidation properties and can be used to facilitate the oxidation process. Depending upon the specific water conditions and Loprest, a division of WRT 901 W. 11611 Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 IUPREST Page 5 corresponding water quality, oxidative media types will perform differently. This pilot study is conducted using two selected media types for side-by-side comparative assessment of the iron and manganese removal performance as well as measured ammonia immediately following media contact for treating these raw ground water sources. A manganese dioxide media trade named Mang-Ox® and a proprietary product from Inversand Co. trademarked GreensandPlus® are tested in two 30-inch tall parallel filter columns. 2.1 Iron and Manganese Removal The most common method of removing iron and manganese from water involves the oxidation of soluble iron (Fe+2, or ferrous ion) and manganese (Mn+2, or manganous ion) to insoluble forms (Fe+3, ferric ion, and Mn+4,tetravalent manganese ion), and subsequent removal of the precipitates formed using filtration. Mang-Ox®is an 80%pure manganese dioxide ore, mined and screened for potable water use. In waters with a positive oxidation/reduction potential(ORP), it can work without the use of an oxidant. Other manganese dioxide ore materials mixed with a variety of sand materials are available under various trade names. GreensandPlus® is a manganese dioxide coated media with a silica sand core. It requires oxidant addition ion prior to media contact. Chlorine is the most common oxidant; however other oxidants are effective. The manganese dioxide coating acts as a catalyst in the oxidation process of both iron and manganese. These medias are evaluated in this testing. F1 filter column contained GreensandPlus® media and F2 filter column contained Mang-Oxv media. 3.0 TEST EQUIPMENT DESCRIPTION WRT/Loprest division's filter pilot test equipment is installed in a 16 ft. x 8 ft. trailer. The pilot test components are installed and pre-plumbed in the trailer for single-point supply and discharge connection at the test site. The filtration equipment includes three (3) test media filtration columns, chlorination and chemical feed addition, and all automated filtration backwash piping valves and instrumentation and process control equipment. Refer to Figure 1 for the pilot equipment general process flow diagram. The following equipment is installed in the trailer unit: • Three (3) Pulsafeeder metering pumps, with a maximum injection flow rate of 3.0 GPD, each with a dedicated solution tank and a 100 mL calibration cylinder. One pump will be used to inject sodium hypochlorite oxidizing reagent, and the second pump will be used to inject ferric chloride (if required). A third chemical injection pumping system is provided for pH control acid addition should this be required. Two chemical reagent metering pumps are required for this pilot test.

The storage tank is used to store filtered water for filter backwash operations. • PLC-based control panel, which automatically controls the filter control valves, subsurface wash and backwash pump during filter cleaning sequences. Filter cleaning sequence initiation can be controlled using elapsed service time, filter differential pressure, or manually. It is anticipated that pressure filter differential pressure will be used as the primary filter cleaning sequence initiation followed by elapsed service time initiation during this pilot testing. • Additional portable test equipment as follows: O Hach DR 900 Portable Colorimeter and accompanying reagent packs for free chlorine measurement, ammonia as well as iron and manganese measurements. o LaMotte DC1500 free chlorine test kit for free chlorine analysis. O Portable handheld probe and analyzer for pH The source water enters the pilot test unit from a connection to the raw water pressurized supply line through a hose connection to the WRT/Loprest filtration system trailer. Raw water sampling occurs at this location referred to as SP1 on the process flow diagram. The water is first directed to the filter column service inlet piping where ferric chloride and oxidant (sodium hypochlorite) reagents are added to the raw water. The pretreated water then enters the top of each media treatment column. The treated water exits the bottom of each treatment column where it is directed to the main discharge piping and out through the outlet connection on the trailer. Each treatment column is equipped with a valved effluent sample connection labeled SP2, SP3 and SP4. The media filter columns are backwashed automatically using one of several backwash trigger points set at the PLC controller. Set points for filter backwash can be initiated manually,by operating time interval,by filter differential pressure loss or by filtered water Loprest, a division of WRT 901 W. 116'Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 IUPREST Page 7 discharge conditions. Based upon the filter run requirements and the testing protocol for the test(s) a filter backwash frequency is selected. Backwashing of the filter units is accomplished by directing treated and finished water from the integrated treated water collection tank. Backwash water supply and a mixed pressurized air supply is directed automatically to each filter column sequentially up flow through the media column to expand the media bed and release the collected solids to exit the out of the top of the filter media column. The backwashed liquid and solids are sent to the wastewater discharge connection on the trailer and directed to a backwash waste collection tank for offsite disposal.

Owner- provided and field measurements for dissolved iron did not return concentrations higher than the corresponding secondary MCL value of 0.3 mg/L. The purposes of this study are to evaluate the removal performance of iron and manganese from the raw water supply by both media types for the purposes of full-scale treatment implementation at well sites 26 and 24 and ensure regulatory compliance for manganese in finished water. 5.0 PILOT TEST PROTOCOL The pilot test consisted of three separate runs for each media type. The flow rate was 1.5 gpm for an 8 gpm/square foot treatment rate in the filter column for all filter runs. 5.1 Operating Procedures and Performance Testing This section describes the steps and procedures that were followed during the onsite pilot study. One of the first steps was the preparation of chemical feed stock solutions. 5.1.1 Preparation of Chemical Solutions Sodium hypochlorite(6.0%)was used to prepare the chlorine solution used during Well 26 filter runs. The dilution factor for the chlorine solution was 1.9 liters of 6 percent sodium hypochlorite into 10 gals of water. Sodium hypochlorite(7.5%)was used to prepare the chlorine solution used during Well 24 filter runs. The dilution factor for the chlorine solution was 2 liters of 7.5 percent sodium hypochlorite into 10 gals of water. Loprest, a division of WRT 901 W. 116'Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 IUPREST Page 11 5.1.2 Operating Procedure The pilot filter columns were loaded, backwashed, and initially preconditioned at the WRT/L,oprest facility. The source of water for the first backwash was potable water from the local potable water distribution system at WRT's facility. After the first backwash,the filtered water from the pilot unit was used for backwashing. Column media was then preconditioned with approximately 4 percent hypochlorite solution for 12 hours. The same media used for the earlier City of Meridian tests was used for the Well 24 and Well 26 testing. Following filter testing at three City of Meridian well sites, the media columns were manually backwashed twice and preconditioned with a chlorine solution prior to the start of the tests. Three runs for each media type were conducted to demonstrate iron and manganese and removal and ammonia reduction capability. Following the conclusion of the three-run pilot test at each well source, the pilot system is relocated to the next well water source for a three-run test. The filter columns were operated continuously for an extended service cycle exceeding the typical backwash frequency to assess actual pressure loss and contaminant removal performance. Each filter run is separated using a backwash cycle. Sodium hypochlorite was added during all filter runs according to the preparation instructions in Section 5.1.1 and the breakpoint chlorination assessments detailed in Section 6.2. The dosing rates for each chemical are recorded on the pilot test log sheets in Appendix B.

All samples are drawn into clean sample containers provided by the analytical laboratory and preserved for metal analysis. Chain of custody documentation is completed, and samples transported to the laboratory for immediate analysis. Test samples are submitted to Eurofins Eaton Analytical in Monrovia, California for analysis using EPA and Idaho state recognized testing methods for drinking water. Methods for analysis are: Total Iron EPA 200.7 Total Manganese EPA 200.7 Ammonia Nitrogen EPA 350.1 5.1.4 Sample Tests Free chlorine, iron, manganese, ammonia nitrogen, and pH were tested onsite using the instruments and procedures described in the following section. Each filter influent and effluent sample was taken in enough volume to provide the required volume for each parameter to be tested. Sample volumes were sufficient to provide a sample for offsite testing as well. The Owner's representative collected samples for the offsite independent lab analysis. 5.1.5 Onsite Test Equipment, Procedures, and Methods Field testing for iron, manganese and ammonia nitrogen are performed with a Hach DR 900. With this instrument, a sample placed within a sample cell, measured twice in the instrument by insertion into the test instrument in two steps,once as a blank for zero setting and again after sample preparation with packet(s) of reagents specific for each constituent. One sample called the blank,is inserted into the DR 900 first, and the instrument is zeroed. Loprest, a division of WRT 901 W. 116`Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 ICiPREST Page 13 The DR 900 measures the amount of light passing through the blank sample and electronically stores the result. Next,the second prepared sample is inserted, and the value is read by the DR 900. The instrument compares the stored value for the blank to the value for the prepared sample and displays the results for the constituent being tested. For manganese, the blank is prepared with deionized water. The iron test blanks are prepared with water from the filter effluent. The test results are displayed on the digital readout. For iron, the Total Iron, FerroVer test Method 8008 is used. For manganese, Method 8149 is used. Ammonia nitrogen tests are performed using Method 8155. Chlorine analysis is performed on a LaMotte DC1500 using the DPD Method. This testis equivalent to Standard Method 4500-C 1 G. pH is measured using an Oakton pH Acorn Series Pocket pH Tester with a range of 0.0 — 10.0 pH. The probe was calibrated daily using a 7.0 pH buffer solution. 6.0 TREATMENT PERFORMANCE EVALUATION This section provides a performance summary of the equipment and media types evaluated during the pilot test. Refer to Section 3.0 for a complete description and specification of the pilot test equipment and field analysis test equipment. 6.1 Filter Head Loss Head loss behavior was consistent between medias, but not between the well systems tested. Pressure loss through the filter media increased for both medias during Well 26 filter runs whereas pressure losses held steady during filter runs performed for Well 24. Table 3 below illustrates the contrasting trend between well sites. Well 26 pilot systems operated under increasing pressure losses with inconsistent starting and ending values. Inlet and outlet gauge pressures and calculations for pressure loss are visible in Section 6.3 and the pilot log sheets in Appendix B.

Figures 2 and 3 display the data from these tests. Recommended hypochlorite doses are estimated for the exceedance of 1 mg/L of free chlorine after the breakpoint, at roughly 2.6 mg/L and 1.9 mg/L of NaOCI for Well 26 and Well 24 respectively. All filter runs operated at hypochlorite addition rates approximately 30% higher than these rates.

viable choices for treating iron and manganese to compliance with USEPA and Idaho State drinking water standards. Both medias removed iron and manganese to below the secondary MCL standard for each. Performance differences between GreensandPlus® and Mang-Ox® are difficult to quantify given the results, although the latter had marginally better reduction of ammonia with double the consumption of free chlorine. The columns were operated at 8 gpm/ft2 and dosed to achieve a free chlorine residual of at least 1 mg/L. Varied feed rates were used between filter runs at each well to determine the optimal chlorine dose, depending on the catalytic properties of both medias and reduction of other contaminants such as ammonia. 7.1 Contaminant removal There are no outstanding differences in contaminant removal performance for Well 26 tests. GreensandPlus® filter effluent had total iron removal, 0.004 mg/L manganese, and 0.02 mg/L ammonia nitrogen. Meanwhile Mang-Oxo filter effluent had 0.01 mg/L iron, 0.007 mg/L manganese, and 0.01 mg/L ammonia nitrogen. Notable however, is that GreensandPlus®had higher free chlorine residuals by at least 35%. Total removal of iron, as well as ammonia, was observed at Well 24 for both media systems. GreensandPlus®runs for this well had roughly double the effluent concentration of total manganese however, only treating to 0.033 mg/L versus 0.014 mg/L using Mang-W. Greensand®yielded higher free chlorine residuals for these filter runs, but by 43% for Well 24. 7.2 Pressure loss Pressure losses during Well 26 filter runs rose during service flows for both media types, ranging between 2 and 3.8 psid. The minimum and maximum head loss in both filters increased each service cycle for the three filter runs performed. Mang-Ox®tended to have lower starting head loss,though matched the pressure losses of GreensandPlus®during the third filter run. This may be attributed to the higher measured iron level in the raw water. Pressure losses during service runs remained steady for both media systems. As seen in Table 3 in Section 6.1, average pressure losses were between 1.9 and 2.3 psid and relative standard deviation below 5%. Backwashes also appeared to be successful at resetting filter operating conditions. 7.3 Recommendations GreensandPlus®is the recommended media type for treatment at Well 26. It will be a more cost-effective choice for the same removal performance with metals and ammonia, while Loprest, a division of WRT 901 W. 116'Avenue, Ste 400,Westminster, CO 80234 • 303 424-5355 IUPREST Page 24 maintaining a higher residual free chlorine. Head loss averaged 0.5 psid greater for GreensandPlus®, though operating pressures increased similarly with each filter run. Mang-Oxo is the recommended media type for treatment at Well 24.
