Adelanto Wastewater Treatment System
Executive Summary
The Adelanto WWTP received 89 million, 381 thousand gallons of raw sewage and successfully treated 89 million, 381 thousand gallons during the month of December 2021, making the total treated amount of water recycled at the Adelanto WWTP about 8.226 billion gallons (since operating services began in December 2012). The characteristics of the water entering and exiting the plant last month are detailed in the section titled “Flows and Laboratory Results.” Secondary effluent form the Facility was discharged to percolation basins 1, 4, 5, & 9 per the discharge requirements for this period. No flow was diverted to VVWRA.

During December, the daily influent flow recorded averaged 2.883 million gallons per day.

Regulation requires when the facility reaches 85% of design capacity the expansion design must be underway. The Adelanto WWTP capacity is 3.0 MGD and therefore the facility design for expansion is overdue.

Effluent flow is being calculated by subtracting the treated flow minus the Waste Activated Sludge (WAS) flow for each day and the daily calculated effluent flow averaged 2.806 million gallons per day.

Throughout the month, PERC Water’s Asset Management Team performed daily process control sampling and analysis, trend analysis, equipment verification checks, compliance sampling, housekeeping, process adjustments, and solids processing. Please see “Plant Staffing” for details about PERC Water’s dedicated Adelanto WWTP team. There were no injuries, accidents, facility tours, regulatory meetings, odor complaints, or security issues this month. No flow was diverted to VVWRA.

The following sections outline the characteristics of the operations of the plant, specifically detailing the influent and effluent quality for the prior month. Questions regarding the quality of the water entering and/or exiting the plant can be directed to David Kachelski via his direct line. We look forward to another month of serving the City of Adelanto, CA.

90 Site Description
The subject site is located in the northern portion of the City of Adelanto, approximately 2,500 feet east of US Highway 395, northeast of the intersection of Auburn Avenue and Jonathan Street, in the County of San Bernardino. A site vicinity map is included as Figure 1. The Southern California Logistics Airport (former George Air Force Base) lies approximately, 0.5 miles due east of the site. The site lies at an elevation of approximately 2,842 feet above mean sea level. With the exception of the Shadow Mountain area north of Adelanto, topography across the area is relatively flat and featureless, sloping gently towards the north-northeast at an average gradient of approximately 25 feet per mile. The only surface water drainage of any observable significance is close proximity to the site is a desert wash that extends in a northwestsoutheast manner about 2,000 feet due west and 3,000 feet due south of the site. This drainage joins Fremont Wash approximately 3.5 miles northwest of the site, and from there finds confluence with he Mojave River near the own of Helendale, approximately 11 miles northeast of the site.

The facility began treating wastewater in 1998 with an initial design capacity of 1.5 MGD. Treated effluent is discharged into a series of excavated percolation ponds along the northern and central portions of the site. Since 1998, the amount of effluent required to be handled by the facility has risen significantly. Recent improvements to the facility have resulted in the significant increase in plant capacity to 3.0 MGD, and as of March 2013, the WWTP no longer bypasses excess wastewater to the Victor Valley Wastewater Reclamation Authority (VVWRA) treatment plant, but handles, treats, and disposes of all waste it receives onsite.

The facility includes ten (10) groundwater monitoring wells (MW-1A, MW-2 through MW-10) that are used to monitor groundwater conditions surrounding the facility.

Groundwater monitoring well locations are depicted on Figure 2.

Well installation activities were conducted in 1998 for wells MW-2 and MW-3, 2011 for wells MW-7, MW-8, and MW-9. Due to the extended screen length in existing well MW1, well MW-1A was installed as a replacement well for well MW-1 to provide a shallower screen depth that were more consistent with wells MW-2 through MW-10.

Current semi-annual groundwater monitoring and sampling only includes wells MW-1A, MW-2 through MW-10. The wells are sampled every April and October as outlined in the WDR permit. A summary of the completion detail is included as Table 1. 91 Geologic and Hydrogeologic Settings
The subject site is located in the high desert region of the Mojave Desert of southern California. The area is situated on a broad erosional plain of coalescing alluvial fans.

Geologic units Characteristic of alluvial fans include interbedded deposits of clastic sediments and eroded debris laid down in high energy fluvial systems such as braided stream channels and flood events typical of desert environments. Subsurface materials included interbedded layers of sands, silts, gravels and cobbles, and other varying mixtures. Clay layers, calcareous soils (cacliche), and evaporite deposits can occur but are generally of limited thickness and areal extent.

The subject site is part of the Mojave River Valley Groundwater Basin (which includes upper, middle and lower sub-basins), and are managed by the Mojave Water Agency.

Regional groundwater flow direction are to the north-northeast toward the Mojave River.

According to the California Department of Water Resources, there are two distinct waterbearing units present in the area of the subject site1 . The first is described as a Pleistocene
and younger floodplain unit (called the “Floodplain Unit”) that extends 50 to 200 feet deep in the Basin. The other is described as a Pliocene and younger fan unit (called the “Fan Unit”) that includes unconsolidated to partially consolidated alluvial fan deposits up to 1,000 feet thick. The available geologic information suggests that the site is primarily underlain by the Fan Unit.

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGING AND SAMPLING Introduction
The Low-Flow purging and sampling technique is the preferred procedure for groundwater sampling under a wide range of hydrogeologic settings. The objective of low-flow/minimal drawdown purging is to obtain a sample that is most representative of the ambient groundwater conditions near the well, taking into consideration aquifer heterogeneities and site-specific subsurface conditions, without imparting bias due to excessive pump rates or formation stress.

The Low-Flow method of purging and sampling involves using a pump to purge water at a constant low rate to achieve field parameter stabilization, while minimizing stress on the aquifer. This method has been well documented as a preferred methodology for collecting representative samples from groundwater (Low-Flow (Minimal Drawdown), Ground-Water Sampling Procedures, Puls and Barcelona, USEPA, April 1996). LowFlow purging is considered by leading researchers as superior to bailing and high-rate pumping and results in a more representative sample than the typical “three volume” well purge methodology or well evacuation.

This procedure is accomplished by measuring field parameters at periodic intervals during purging with a flow cell container. The flow cell is an inline purge cell, which will allow the sample technician to constantly monitor field water quality parameters such as temperature, pH, dissolved oxygen, and conductivity. Other techniques or containers can be used to collect samples for periodic measurements, provided that periodic and representative samples can be collected.

The following sections provide a general discussion on each aspect of the Low-Flow procedure with bulleted items being procedural steps.

Equipment
Dedicated pumps are ideal for low flow purging. Sites that have observation wells without dedicated pumps will require the use of portable (non-dedicated) pumps (bailers cannot to be used for low-flow purging). The sampling team should have all equipment necessary for purging and sampling wells at low flow rates. Other equipment may include:
o Water Level Tape or other water level measuring device; o Flow cell to monitor field parameters;
o Calibrated purge water container;
o Dedicated pump system or disposable sample tubing (for non-dedicated pumps); and
o Field Meters for pH, Temperature, Dissolved Oxygen, and Conductivity/Specific Conductance.

Prior to each sampling event the field probes will be calibrated in accordance with the owner’s manual provided and the site-specific sampling plan. Field probes should be checked for drift every four hours or at the end of the day at a minimum. 107

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 1 It is important to identify the range, resolution and accuracy of the instruments used to determine if the selected stabilization criteria can be measured. If the instruments available cannot accurately measure the stabilization criteria above, consult with the regulatory program manager to determine if different criteria values would be appropriate for your sampling program.

Decontamination
Sites that have observation wells without dedicated pumps will require the use of nondedicated pumps. All non-dedicated equipment used during the purging and sampling process must be decontaminated prior to each use, including tubing, unless it is disposable):
o Downhole equipment, such as a water level indicator, is to be triple-rinsed between well locations.
o Discard disposable polyethylene tubing used with non dedicated pumps after use at each well.

Sample bottles will be provided and properly prepared by the analytical laboratory scheduled to perform the analysis. No cleaning or preparation of sampling bottles by field personal will be performed.

Purge Volumes and Monitoring Frequency
Low-flow purging does not require the calculation of the water volume in the well, since purging is based solely on indicator parameter stabilization. Rather, the volume of the pump and discharge tubing are necessary for making calculations needed to determine field measurement frequency and/or the minimum purge (“passive”) sampling system purge volume. Pump chamber or bladder volumes can be obtained from the manufacturer. Volumes of the sample tubing can be calculated or taken from the table below.

Discharge Tubing Volumes
Tubing Diameter Volume/foot
1/2" OD/3/8” ID 20 ml
3/8” OD/1/4” ID 10 ml
1/4" OD/1/8” ID 5 ml
Well casing volumes should only be calculated if required by Permit or State Regulation and recorded on field information forms. In addition, well casing volumes may be needed in any case where parameter stabilization is not achieved after a three-casingvolume purge (see below).

Sampling equipment volumes are calculated or recorded for use in determining the frequency of field measurements. Depending on the equipment configuration, calculate and record the volume of the pump and sample tubing using the methodology described 108

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 2 above (the volumes are typically converted to liters). The frequency of field readings is based on the time required to purge at least one volume of the pump and tubing system. For example, a pump and tubing volume of 500-ml purged at a rate of 250 ml/minute will be purged in two minutes; readings should be at least two minutes apart.

In any case, it is important to ensure that the field parameters are measured on independent samples of water.

Purge Rates
The objective of the purging process is to remove sufficient water from within the well screen zone to result in a sample that is representative of actual aquifer conditions adjacent to the well. The sampling pump or pump intake should be located within the well screen. This pump location is already established for dedicated pumps. For nondedicated pumps, the intake is placed within the screened interval, typically in the center of the screen. If the water column in the screen is shorter than the overall screen length, the pump should be placed lower in the screen but no lower than about 6-12 inches from the bottom of the screen to avoid picking up any settled solids in the well.

A low pumping rate (typically less than 1,000 ml/min) is used to minimize drawdown within the well and formation and mobilization of formation solids. Lower flow rates may be required during sampling. Flow rate is determined by measuring the time it takes to fill a calibrated container, or by measuring the volume of one pump discharge cycle and multiplying this volume by the number of cycles per minute (e.g., 125 ml/cycle x 4 CPM = 500 ml/min). Drawdown is monitored by measuring the water level below the top of the well casing with a water level indicator or similar device (e.g. transducer) while pumping. Drawdown will be stabilized during purging. Flow rates and drawdown are recorded on a field log, field data form or with a data logger. o Measure water levels prior to initiating purging;
o Calculate well volumes, if required by permit;
o Calculate sampling system volume and determine indicator parameter measurement frequency;
o Lower water level meter probe to 1-2 feet below static water level; o Connect the flow cell to the discharge tube from the pump; o Begin purge at a rate of 100-200 ml/min (or at a rate determined from prior events);
o Check drawdown with a water level tape while pumping; o If drawdown stabilizes quickly, increase the pumping rate in increments of 100 ml/min until drawdown increases, then reduce the rate slightly after a few minutes to achieve a stable pumping water level;
o If the water level continues to drop, reduce purge rate by 100 ml/min increments until the water level stabilizes;
o Once water level stabilization is achieved, proceed to indicator parameter stabilization.
109

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 3 Parameter Stabilization
Parameter stabilization ensures that the well is adequately purged and sampled groundwater is representative of formation water. In order to determine when a well has been adequately purged, samplers should:
o Monitor pH, specific conductance, and dissolved oxygen of the ground water removed during purging;
o Observe and record the water level drawdown; and
o Record the purge rate and note the volume of water removed if required by guidance or permit.

A well is adequately purged when the pH, specific conductance, and dissolved oxygen stabilize. Stabilization occurs as follows:
pH: +/- 0.2 pH units
Conductance: +/- 5 % of reading value
Dissolved oxygen: +/- 10.0% or 0.2 mg/L, whichever is greater.

Temperature is not a reliable indicator of stabilization, being affected by ambient temperature at the well head, sunlight, and some sampling devices such as electric pumps. Temperature is typically measured to provide correction for temperature dependent parameters (e.g., DO % saturation, pH, and specific conductance).

While turbidity is not a direct measurement of water chemistry and is not used as an indicator parameter of stabilization, it is useful to support data from metals analyses. To avoid artifacts in sample analysis, turbidity should be as low as possible when samples are taken. Turbidity should be measured at least three times, once when purging is initiated, again after the water level in the well stabilizes, and again when the water chemistry indicator parameters being measured are stable. Turbidity should also be measured any time the pumping rate is increased or the water level in the well drops noticeably. If the initial turbidity reading is high (>50 NTU) and the second reading is not significantly lower, the pump rate should be reduced. The turbidity value measured prior to sampling will be recorded. If this value exceeds 50 NTU, procedures should be reviewed and the source of the elevated turbidity determined.

Sampling
Wells should be sampled immediately upon completion of purging operations. Once the water level stabilizes, the purge rate should remain constant during low-flow sampling (generally less than 500 ml/min). For VOCs, lower sampling rates (100 - 200 milliliters/minute) may be required.
o Record field parameters prior to sampling;
o Record depth to water levels prior to sampling (note if the well has not stabilized). 110

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 4 o Record the flow rate determined using a calibrated measuring device; o Disconnect the flow cell other equipment from the pump discharge tube; o Collect samples from the pump discharge tube
o Collect large volume samples first (e.g.,1 liter bottles), then VOC samples, and any filtered samples last;
If, after three well volumes have been removed, the chemical parameters have not stabilized according to the above criteria, the sampling team may elect to collect a sample. The conditions of sampling should be noted in the field log or field information form.

Low Yield Formations
In some situations, even with very slow purge rates, the well drawdown may not stabilize. In this case, sampling the water within the well screen zone provides the best opportunity to determine the formation water chemistry, as well evacuation can greatly affect sample chemistry through changes in dissolved gas levels, dissolved metals and VOCs.

Attempts should be made to avoid purging wells to dryness. This can usually be accomplished by slowing the purge rate. If the well is evacuated during the purging procedures shown above, the sample may be collected as soon as a sufficient volume of water has recovered in the well. If the well goes dry repeatedly (i.e. over multiple monitoring events) prior to sampling, then a minimum purge or “passive” sampling approach should be used in lieu of well evacuation.

Minimum Purge (“Passive”) Sampling
For wells that cannot achieve a stabilized water level and purge dry even at very low pumping rates, an alternative to the traditional evacuation approach is to use minimum purge (sometimes called “passive”) sampling techniques to avoid the pitfalls of well evacuation and obtain a better estimation of the formation water quality. Sampling the water present in the screen zone provides the greatest chance of obtaining samples with minimal alteration of the chemistry. Although the low movement rate of the ground water in the screen provides only a limited exchange, avoiding the alteration caused by the factors mentioned above is really the best alternative.

The minimum purge approach requires the removal of the smallest possible purge volume prior to sampling, generally limited to the volume of the sampling system. The sampling system volume is minimized by using very small diameter tubing and the smallest possible pump chamber volume. Plastic tubing should have sufficient wall thickness to minimize the potential for oxygen transfer through the tubing when pumping at very low flow rates. After purging 1-3 volumes of the sampling system, samples are taken from the subsequent water pumped. Since minimum purge sampling requires the minimum possible disturbance to the water column and surrounding formation, dedicated sampling systems are required for this approach. 111

PROCEDURE FOR LOW-FLOW (MINIMAL DRAWDOWN) PURGE AND SAMPLING 5 The pumping rates used for minimum purge sampling are much lower than for low-flow purging, generally 100 ml/minute or less. Drawdown is expected, since it cannot be avoided; however, it is still advisable to pump at the lowest possible rate to limit drawdown to the minimum possible. Monitoring indicator parameters for stability is not part of this approach, since the intention is not to purge until stabilization of these measurements. The pH, specific conductance and turbidity or any other required field parameters should be measured during collection of the sample from the recovered volume. Regulatory approval should be obtained prior to collecting a sample using this method.

Field Records
Field information must be recorded during purging and sampling. At a minimum, the following information should be included in the field forms for each groundwater monitoring well.

o Purge Information (pumping rate, purge volume if required); o Equipment Specifications (pump type, filter type and pore size if used); o Well Data (depth to water, total depth, groundwater elevation); o Field Measurements during purging and at the time of sample collection; and o General weather conditions or other comments
This data is to be recorded on field forms and/or in a data logger.

Other Technical Issues
The following are other technical issues addressed as follows by the facility:
o Dedicated pump intakes are generally set at the middle of the screen. Where water levels have dropped due to drought conditions, the sampling team may lower the pump in order to obtain sufficient sample.
o For wells installed in bedrock, packers are only required to seal off the zone of interest if the bedrock has been determined to be competent (e.g. is not highly fractured).
o The flow cell system does not require decontamination between wells, because the act of purging removes any liquids from other wells and because sampling takes place upstream of the flow cell and only after disconnecting the pump discharge tubing.

Capital Improvement Plan (CIP) Report
In the past 10 years, the City of Adelanto’s population has grown by more than 25% (U.S. Census).

The City’s current water treatment system, already straining to accommodate Adelanto residents, will not supply enough water for incoming businesses and continued population growth. The following is a summary of the needed repairs and updates (Type 1 and Type 2) associated with the water system, the estimated cost and status. These repairs and updates are essential to the future of Adelanto’s water supply. Below is an updated list of the CIP items:

Type 1 CIP Items: Repairs and/or replacements for which: i) the scope of work is presently known/defined without the need for the additional engineering support; and/or ii) qualified service providers/contractors can readily be solicited to provide cost quotations to complete the required scope of work pursuant to the City’s established procurement processes.

Current Issues with the Iron and Manganese (I & M) System These issues need to be given priority as they are essential to water system function and water quality.
• The chlorine storage tanks need to be replaced as chlorine in liquid form degenerates rapidly
• Both raw and finished water tanks have been inspected and are both severely corroded and need to be replaced.
• 1200 Booster #1 is in need of replacement. Update: booster is installed and awaiting parts for startup (Complete)
• 1200 Booster #1 switchgear is not to code and needs to be replaced. 156

CITY COUNCIL AGENDA REPORT
DATE: January 26, 2021
TO: Honorable Mayor and City Council Members
FROM: Jessie Flores, City Manager
BY: Marc Tran, City Attorney
SUBJECT: DECLARATION OF SURPLUS PROPERTY PURSUANT TO AB 1486 – 12000 STADIUM WAY, ADELANTO, CALIFORNIA 92301 (APNS 3128-221-18; 3128- 221-19; 3128-221-21; AND 3128-221-22)
STAFF RECOMMENDATION:

It is staff’s recommendation that the City Council adopt the attached Resolution and declare the property located at 12000 Stadium Way, Adelanto, California 92301 (APNs 3128-221-18; 3128-221-19; 3128- 221-21; and 3128-221-22) is surplus land and is no longer necessary for the City’s use and direct the City Manager to follow the procedures set forth in the Surplus Land Act as amended by AB 1486.

BACKGROUND:

The City Council of the City of Adelanto owns, and controls real property located at 12000 Stadium Way, Adelanto, CA 92301 (APNs 3128-221-18; 3128-221-19; 3128-221-21; and 3128-221-22). The Site contains various structures located over four parcels. The Site is zoned for Mixed Use (Residential/Commercial).

The California Surplus Land Act requires all local agencies to prioritize affordable housing, parks, and open space when disposing of surplus land. To proceed with an eventual sale of the Site, the City Council must comply with the Surplus Land Act.

AB 1486, which amended the Surplus Land Act, requires that before a local agency takes any action to dispose of land, the land must first be declared either “surplus land” or “exempt surplus land”, and such declarations must be supported by written findings. (Gov. Code § 54221 (b)(1).) “Surplus land” is defined as “land owned in fee simple by any local agency for which the local agency’s governing body takes formal action in a regular public meeting declaring that the land is surplus and is not necessary for the agency’s use.” (Gov. Code § 54221, subd. (b)(1).)
In short, AB 1486 requires the City Council to take formal action declaring that the Site is surplus property. Adoption of the attached Resolution would satisfy that requirement.

If and when the City Council adopts the attached Resolution, the procedures set forth in Government Code section 54220 et seq. must be followed to dispose of the property. More specifically, the procedures require that the City Council offer the sale or lease of the property to certain public entities for a period of sixty (60) days by transmitting a written notice of availability to those entities, including:
174

1. A written notice of availability to any “local public entity” (Health & Safety Code § 50079) within whose jurisdiction the surplus land is located and to “housing Sponsors” that have notified the California Department of Housing and Community Development (“HCD”) of their interest in surplus land.

2. A written notice of availability of the surplus land to local park districts.

3. A written notice of availability to local school districts.

4. A written notice of availability to any other public entities with jurisdiction over the surplus land.

If the City Council receives correspondence expressing interest from any of the above entities, the City Council is required to enter into good faith negotiations concerning the price and terms of the sale with that entity for a period of ninety (90) days. If the price and terms cannot be agreed upon after ninety (90) days or if no entity gives notice of interest, then the City Council may sell the surplus land without further regard to the surplus land procedures.

CONCLUSION:

The City Council should adopt the attached Resolution to comply with AB 1486 and declare the Site as surplus property.

FISCAL IMPACT:

No fiscal impact at this time.
