1. Water Hardness must be comparable to MWD supply in the range of 180 to 250 milligrams/Liter (mg/L), measured as calcium carbonate.

2. Total Dissolved Solids (TDS), a measurement of salinity, must be in the range of 500 to 750 mg/L.

3. Taste and odor must be palatable.

Changed Conditions (Process Improvements Since 2010) Since 2010, the City has completed a number of on-site and off-site water improvements that have improved the water quality and overall operation of the CWPF and Well No. 5.

• In 2011, the City replaced old undersized water mains under Pacific Coast Highway (from the western City limit to Narbonne Avenue) which enhanced the hydraulics of the Reservoir.

• In 2012, the City installed a temporary blend pipeline at the CWPF enabling

MWD import water from Zone 2 to blend with the treated well water from Zone 1. Blending from Zone 2 allows a higher pressure and capacity water to blend with the treated well water.

• The City implemented temporary piping modifications to better aerate and mix

the water in the Reservoir. Test Purpose Hazen and Sawyer, an engineering and scientific firm that consults only on the subjects of water and wastewater, was retained to test the treatment and operation of the system while it was off-line to determine if it could meet water quality goals established by the City Council on September 4, 2012. Off-Line Testing The quality of the well water was carefully tested and analyzed to consider the potential causes of previous complaints and to evaluate the possible range of adjusting operations of the existing treatment and production facilities to improve the water quality. After a one-week period for starting up and checking the functioning of the system, a three week test was conducted. Laboratory analyses were conducted to measure the improvement of water quality through the treatment facility. Flavor panelists conducted flavor profile analyses to help identify any taste and odor issues and recommendations to adjust the system operations to achieve the best taste and odor after treatment and storage at the CWPF.

The second method of managing water quality at the CWPF is to blend the treated well water thoroughly with MWD water at the plant and in the tank. Two blends were tested at 60% well and 40% MWD water, followed by 50% well and 50% MWD water. Blending with MWD water that usually has lower TDS and hardness produced a finished water to meet the previously established water quality objectives. Because MWD uses chloramines for preventing pathogens, it is compatible in blending with Lomita’s treated well water.

Results The test results concluded that the water quality objectives were successfully met. The TDS of the blended water was within the target range of 500 to 750 mg/L and the hardness was in the range of 180 to 250 mg/L as Figures 1 and 2 demonstrate. Hardness in the blended water will be at levels to ensure that home appliances and water pipelines will not be adversely impacted. Figure 1: Total Hardness (as Calcium Carbonate)

Next Steps The water meets all regulatory acceptance levels, including health and aesthetic based limits. A full Title 22 analysis of the well water shows that the source water meets all limits. The treated and blended water is ready for the community to taste and give their opinions about its acceptability. Community tasting will begin with the City Council at the December 3, 2012 meeting and if approved by the Council, will continue as part of the City’s ongoing Public Education and Outreach Program outlined below. Community Outreach / Public Education Campaign The Community Outreach / Public Education campaign will be conducted by Hazen and Sawyer and will consist of the following items:

1. Conduct at least one community meeting to educate and survey opinions and concerns regarding the groundwater quality.

2. Conduct taste testing at City Council Meetings and select Commission/Board Meetings. At these meetings, the public will be invited to participate in the taste testing as well.

3. Conduct meetings and taste testing at local meetings of service clubs, churches and other community organizations.

4. Utilize the City’s website, city newsletter, and possibly newsprint to disseminate information and educate the public on the water quality issues and the remedies being undertaken by the City to address these issues.

5. Where feasible, maximize the use of social media (i.e., Facebook) to educate the public.

Notes:

The Chain of Custody document is part of the analytical report.

Any remaining sample(s) for testing will be disposed of one month from the final report date unless other arrangements are made in

advance.

All results are expressed on wet weight basis unless otherwise specified.

An Absence of Total Coliform meets the drinking water standards as established by the State of California Department of Health Services.

The Reporting Limit (RL) is referenced as laboratory's Practical Quantitation Limit (PQL).

For Potable water analysis, the Reporting Limit (RL) is referenced as Detection Limit for reporting purposes (DLRs) defined by EPA.

If sample collected by Weck Laboratories, sampled in accordance to lab SOP MIS002

The results in this report apply to the samples analyzed in accordance with the chain of custody document. Weck Laboratories certifies

that the test results meet all requirements of NELAC unless noted in the Case Narrative. This analytical report must be reproduced in its

entirety.

Authorized Signature

Flags for Data Qualifiers:

MS-01 The spike recovery for this QC sample is outside of established control limits possibly due to sample matrix interference.

MS-05 The spike recovery and/or RPD were outside acceptance limits for the MS and/or MSD due to possible matrix interference.

The LCS and/or LCSD were within acceptance limits showing that the laboratory is in control and the data is acceptable.

Q-08 High bias in the QC sample does not affect sample result since analyte was not detected or below the reporting limit.

ND NOT DETECTED at or above the Reporting Limit. If J-value reported, then NOT DETECTED at or above the Method

Detection Limit (MDL).
