3 Bckgrund On Mrch 15, 2013, the City f Lmit received cnditinl pprvl frm the Deprtment f Public Helth (DPH) t distribute blended wter frm the Cypress Wter Prductin Fcility (CWPF) Well N. 5 t the City s custmers. The CWPF is n irn-mngnese greensnd filtrtin tretment system designed t remve primrily irn, mngnese, nd clr. The CWPF ws recently mdified t enble ertin nd blending with Metrplitn Wter District (MWD) imprted wter t ddress the esthetic secndry issues f Ttl Disslved Slids (TDS), Hrdness (s Clcium Crbnte), nd Tste/Odr. The CWPF cme nline n April 1, The first week f pertins frm April 1 t April 5, 2013 ws utilized fr cnducting rutine strtup ctivities. The distributin f blended wter t the City s residents begn n April 5, Well Prductin nd Opertins Fr the mnth f Februry 2015, the CWPF perted fr pprximtely 28 dys, prviding blended wter n fill nd drw cycle with the reservir level fluctuting with system demnd. The ttl prductin frm Well N. 5 fr the mnth ws pprximtely c-ft (18,426,987 gllns) with dily prductin f pprximtely 2.02 c-ft. The ttl cmbined prductin frm bth MWD imprt wter nd Well N. 5 ws pprximtely c-ft (32,914,729 gllns) fr the mnth with cmbined dily prductin f pprximtely 3.61 c-ft. The dily verge flw frm Well N. 5 ws 748 gpm. The verge flw frm the Well ws determined by tking n verge f the dily reds prvided n the Dily Mnitring lgs used nsite. The blend rti fr this mnth ws n verge 56% Well wter nd 44% MWD wter. Opertinl nterruptins There were n mjr pertinl interruptins during the mnth f Februry Rutine nd preventive mintennce ws perfrmed n vrius pieces f equipment s-needed. N mjr plnned pertinl interruptin is nticipted fr the fllwing mnth. Smple Lctins Cmplince mnitring is perfrmed t the fllwing smple lctins: SP1, SP2, SP3, SP5, nd SP6. The SP1 smple lctin is the rw well wter smple lctin. The SP2 smple lctin is n the effluent side f the greensnd filter (befre mmni injectin r full chlrmintin). The SP3 smple lctin is dwnstrem f the greensnd filter fter full chlrmintin nd the sttic mixer befre entering the reservir. The SP5 smple lctin is the reservir effluent smple lctin befre entering the distributin system. The SP6 smple lctin is the MWD surce smple lctin befre blending ccurs. 2 P ge

The CWPF hs been cntinuusly mnitred, mintined nd inspected, per the CWPF Opertins Mnitring nd Mintennce Pln. A brief discussin f the lbrtry nd/r mnitring results is prvided belw.

The TDS level f the effluent wter meets the City s Wter Qulity Objective/Gl f 500 t 750 mg/l. The smpling results indicte the TDS levels in the rw wter nd MWD wter surce t be 700 mg/l nd 610 mg/l, respectively. E. Hrdness The smpling results fr the mnth f Februry indicte the hrdness levels f the blended wter t be 290 mg/l. Althugh, this hrdness level is in the upper rnge f the City s Wter Qulity Objective/Gl f 180 t 250 mg/l; stff cntinues t mnitr hrdness levels t the CWPF effluent (SP5) nd within the wter distributin system. The City hs mintined cnsistent blend rti t ensure cceptble hrdness levels re met. Stff cntinues t use n rthphsphte/plyphsphte dditive t sequester clcium hrdness. Orthphsphte/Plyphsphte is fd grde Ntinl Snittin Fundtin (NSF 60) pprved dditive which decreses irn tubercultin, diminishes clcium scle depsits, minimizes crrsin, reduces disclrtin, reduces stining nd minerl build-up resulting in fewer custmer cmplints. F. Disslved Methne (in Wter) The methne levels in the CWPF effluent fter ertin tretment remin negligible verging 0.68 mg/l. G. Methne (in Air) The methne levels in the reservir hedspce re mnitred dily by stff using hndheld device. These redings hve cnsistently red nn-detect t lw cncentrtins fr methne in ir.
