4 A. BACKGROUND On Mrch 15, 2013, the City f mit 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, B. W PRODUCTON AND OPRATONS Fr the mnth f July 2015, the CWPF perted n fill nd drw cycle prviding blended wter with the reservir level fluctuting with system demnd. The Cypress Reservir filled nd drew fr pprximtely 21 dys nd 10 dys, respectively. The Cypress Reservir effluent vlve remined pen fr the entire mnth f July The ttl prductin frm Well N. 5 fr the mnth ws pprximtely c-ft (14,694,625 gllns) with dily prductin f pprximtely 2.15 c-ft. The ttl cmbined prductin frm bth MWD imprt wter nd Well N. 5 ws pprximtely c-ft (39,165,610 gllns) fr the mnth with cmbined dily prductin f pprximtely 5.72 c-ft. The dily verge flw frm Well N. 5 ws 496 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 38% Well wter nd 62% MWD wter. C. OPRATONA NTRRUPTONS On July 20, 2015 the Cypress Wter Prductin Fcility ws ffline due t severl pwer spikes cusing the well t shut dwn. Wter within the Cypress Reservir remined unffected nd the plnt ws put int drwdwn mde. The well ws put bck nline the fllwing dy, resuming nrml pertins. Rutine nd preventive mintennce ws perfrmed n vrius pieces f equipment s-needed. N mjr plnned pertinl interruptins re nticipted fr the fllwing mnth f August D. SAMP OCATONS 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 3 P ge

5 the reservir effluent smple lctin befre entering the distributin system. The SP6 smple lctin is the MWD surce smple lctin befre blending ccurs.. WATR QUATY MONTORNG All wter qulity mnitring nlyses were perfrmed by lbrtries certified by the Deprtment f Helth s nvirnmentl brtry Accredittin Brnch (AB). 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. Refer t Appendix A fr lbrtry results. 1. RON, MANGANS AND COOR See Tble 1 belw fr summry f the results fr the cmplince mnitring t the three smple lctins SP1 thrugh SP3. Clr in the rw wter (SP1) fr the mnth ws belw the Mximum Cntminnt evel (MC). rn cncentrtin in the rw wter (SP1) ws t the MC. Mngnese cncentrtin in the rw wter (SP1) ws bve the MC. rn nd Mngnese levels entering the reservir (SP3) were nn-detect, indicting the greensnd filtrtin system remins highly effective. Other dditinl bcterilgicl lbrtry smples cllected included Ttl Clifrm nd Hetertrphic Plte Cunt (HPC) levels n the effluent side f the greensnd filter (SP2) shwing bsent fr bth. 2. FR AND TOTA CHORN RSDUAS Dily free chlrine residuls were mnitred t SP2, SP3 nd SP4. Dily ttl chlrine residuls were mnitred t SP3 nd SP5. Free chlrine nd ttl chlrine residuls, t ll respective smple pints, were mnitred using cmbintin f cntinuus chlrine nlyzers nd SCADA. See Tble 2 belw fr weekly summry f results. 3. TOTA DSSOVD SODS (TDS), ODOR, HARDNSS AND MTHAN See Tble 3 belw fr summry f the results fr the mnitring f Ttl Disslved Slids (TDS), Odr (s mesured by the Threshld Odr N. - T.O.N.), Ttl Hrdness s Clcium Crbnte, nd Methne levels in wter t three smple lctins SP1, SP5 nd SP TOTA DSSOVD SODS (TDS) The smpling results indicte the TDS levels f the effluent blended wter t be n verge 706 mg/. The TDS level f the effluent wter meets the City s Wter Qulity Objective/Gl f 500 t 750 mg/. The smpling results indicte the TDS levels in the rw wter nd MWD wter surce t be 620 mg/ nd 670 mg/, respectively. 3-2 HARDNSS The smpling results fr the mnth f July indicte the hrdness levels f the blended wter t be 310 mg/. Althugh, this hrdness level is in the upper rnge f the City s Wter Qulity Objective/Gl f 180 t 250 mg/; stff cntinues t mnitr hrdness levels t the CWPF 4 P ge

6 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. 3-3 DSSOVD MTHAN (N WATR) The methne levels in the CWPF effluent fter ertin tretment remin negligible verging 0.62 mg/. 3-4 MTHAN (N AR) 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. Avilble methne hnd held mnitring instruments cn nly detect levels f 1% wer xplsive imit () r greter. The hndheld methne redings during the mnth were belw the 50,000 ppm. See ttched methne lg fr the mnth f July 2015 in Appendix B. F. TABS Tble 1. Mnitring Results fr SP1, SP2, nd SP3 Smple ctins.
