Presentation Transcript
What is Fluoride Naturally occurring mineral 13thmost abundant element in Earth s crust The stuff they put in water and toothpaste Proven to help prevent cavities Helps with bone density Found to stimulate new bone formation
Fluoride Toxicity Dental Fluorosis in children under 9 White streaks, brown stains, or pitting of tooth enamel Skeletal Fluorosis Bones become brittle, joints stiffen, and mobility impaired. Acute Toxicity Nausea, vomiting, abdominal pain, and other more severe symptoms Studies are being conducted on the effects of Fluoride on the brain Oxidative Stress in brain tissue damaging neurons and brain function Kidney Damage Renal tubular damage, causing increased Fluoride retention
Fluoride Levels in the Water Max Contaminant Level (MCL) CA 2.0mg/L EPA 4.0 Pinon Pines Running Averages Well 5 2.3 mg/L Well 6 1.9 mg/L Avg 2.5 mg/L Well 7 3.2 mg/L
Whats Being Done Fluoride Mitigation Project 2004 Application Process Began State Revolving Fund (SRF) Construction Funds Application (CFA) 2008 SRF Processed Prop 84 for Grant Funding 2009 CFA converted to Planning Funds Application (PFA)
Whats Being Done 2016 Blending Study May 2017 Public Hearing June 2017 Community Vote July 2017 State Acceptance for Variance 2018 Blending Study Revised
Whats Being Done Present Day 2020 Final Budget Approval (FBA) $2,031,810 Construction Completion 03/31/2023 2022 FBA Amendment Filed $4,203,712 Construction Completion 01/02/2024 2023 & 2024 FBA Amendment(s) Filed (PENDING) $5,078,061 Construction Completion 12/31/2025
What Does That Do for Us Demolition of 2 Old Storage Tanks Construction of 1 Larger Storage Tank Drilling of a New Well Construction of a Blending Facility
Where Are We in the Project 2 Storage Tanks Demolished 1 Larger Storage Tank Built 1 Blending Tank Built 1 Well Drilled Most of the Pipes Are in Ground and Ready
What is Left to Do Blending Facility Building Construction Pipe Connections from Wells to Blending Facility Pump Installation inside Blending Facility Pipe Connection from Blending Facility to Distribution System New Well Pump Installation New Well Building Construction Electrical Line Installation and Motor Control Center Supervisory Control and Data Acquisition (SCADA) Install
Blending Facility Tank Footprint 176.6 ft Dimensions D = 15 and H = 19 3 Safety Railing above Tank Capacity ~22,000 Gallons 1/3 Daily Winter Usage 1/6 Daily Summer Usage
Blending Facility Building Footprint 640 ft (32x20) Three-Car Garages Range 600 ft to 864 ft 2-40Hp Booster Pumps 70 dB (vacuum) to 90 dB (lawnmower) Building is Insulated will lower dB outside the building
Blending Facility Building Are the Pumps Going to Run All Day!? NO Wells and Pumps Run 8 am 4 pm Unless the tanks fall below 70% capacity (Safety) Are There Plans to Beautify the Facility? Yes (nothing definitive yet) PPMWC and the HOA will work together after the project is completed to see what can be done. Is the Blending Tank Going to Stay Red? No The tank will be painted an off-white Almond color The Red is a protective coating for the welding
Questions The Floor is Open for Questions.
