• Requires a formal transmittal of the plan on letter after jurisdictional determination

is complete

• Tentative USACE meeting scheduled on August 6th
• RES was asked for a proposal to include these properties

CLI CLICK TO TO EDIT EDIT MAST MASTER TITLE TITLE ST STYL YLE

• There are options to address additional acreage
• Option 1 – Plan presented to USACE on 6/25 (No new property

acquisition required)

• RES price to mitigate = $9,759,869

AGENDA

Discussion Items

• G. Water Quality Parameters

FLUORIDATION North Texas Municipal Water District History

• October, 1980 - NTMWD hosted a Fluoridation Seminar conducted by

the Texas Department of Health.

• North Texas Municipal Water District was urged by several cities to

proceed with fluoridation of the drinking water. (In 1980 the Cities of Garland, Plano, and Mesquite were providing fluoride locally. )

• In March 1981, the NTMWD Board of Directors approved a program for

the installation of fluoridation facilities. Black & Veatch, Inc. was asked to prepare plans and specifications for fluoride facilities.

• On May 1, 1982 the NTMWD began fluoridating the water with

hydrofluosilicic acid (HSF).

FLUORIDATION NTMWD Treatment Process

• Naturally occurring fluoride concentration in NTMWD water supplies is

approximately 0.30 mg/L.

• HSF added to produce a concentration of approximate 0.70 mg/L per

the U.S. Department of Health and Human Services recommendation.

• Drinking water additives must meet National Sanitation

Foundation/American National Standards Institute (NSF/ANSI) 60 standard to become certified.

• The company submits an application and provides product formulation,

toxicology and product use information.

• The NSF toxicology department reviews formulations.
• NSF inspectors perform a plant audit, sample collection and independent

testing.

• NSF completes a final toxicology evaluation.

FLUORIDATION State of the Industry

Percentage of U.S. population receiving fluoridated water 66.2% Percentage of U.S. population served by community water systems that adjust fluoride 95.1% (this is 95.1% of the 66.2% statistic above) Percentage of Texas population served by community water systems that receive fluoridated water 80.4%

There are 5975 Public Water Systems in Texas. Approximately 44% of the systems (2614 public water systems) add fluoride. Fluoride concentrations for utilities that add fluoride are:

• Average: 0.67 mg/L
• Median: 0.85 mg/L
• Mode: 0.70 mg/L
