ater resources planning in Texas requires looking fifty years out to guarantee that the growth of a community can be supported by the available water supply. It's a continuous effort, as such plans are always evolving as the underlying assumptions change.

Developing the water professionals to implement these carefully crafted water supply plans is also a continuous effort, as recognized by the TAWWA Scholarship Committee and Education Division.

ALISSA LOCKETT Outreach to elementary, middle and high school 210-233-3401 students is effort well spent so we can guarantee alissa.lockett@saws.org that the next generation of Texans has a reliable water supply, and the Education Division is on the spot to provide tools to aid in this outreach. If you are interested in volunteering, please contact Christianne Castleberry or visit the TAWWA website for more information.

This year, TAWWA awarded sixteen scholarships to deserving students across the state, with a number of additional scholarships to be awarded

by Chapters. Extra points for students pursuing a career in water are prevalent in the Chapters’ evaluations of scholarship recipients, as we want to cultivate the future leaders in this industry. With that goal in mind, the TAWWA Mentoring Committee has kicked off with initial discussions between mentors and mentees already underway. The program is in its infancy but is gaining traction fast, so if you are interested in being a mentee or mentor, please contact Letty Gomar or visit the TAWWA website for more information. You are never too old or experienced to be a mentee, so do not be shy to sign up even if you consider yourself a “seasoned” professional. You can even be a mentor and mentee at the same time.

Another investment in our future are training opportunities, such as the November 7 webcast on Zebra Mussel Control Strategies coordinated by the Water Quality & Technology Division. Check out the Community Calendar on the TAWWA website for upcoming events so you can learn about current issues, obtain professional development hours and/or continuing education units and network with other water professionals.

Supporting Higher Education

BY MIKE HOWE tawwa executive director

I

n the grand scheme of all that our members do in the water community, some of the most rewarding efforts are the philanthropic programs we support, such as Water For People and our scholarship programs.

For the last three years, members of the Texas Section have raised more than $50,000 each year for Water For People. And, over the last few years, we have funded at least fifteen $2,000 scholarships totaling $30,000 on the state level and any number of additional scholarships at the Chapter level. And, this year, in a partnership with Alan Plummer Associates, their firm funded an additional $3,000 scholarship for one of our members. In total, since our scholarship program began many years ago, we have funded nearly $500,000 in scholarships for higher education.

In one word, these efforts are "remarkable."

You might wonder where these funds come from.

About half of the Section scholarship funds are from interest we earn from our investments. But, the balance of these funds come from events such as the Scholarship golf tournament at the Texas Water Conference, and your generosity in direct donations.

The need for your direct donations is becoming more and more important.

This past year, we had 54 applications for scholarships from very worthy students.

Our Scholarship Committee has the difficult task of determining which of those students are ranked to receive scholarships, and of course, to determine who MIKE HOWE don’t. This task is extremely 512-238-9292 mikehowe@tawwa.org difficult, as far more than the fifteen students are more than deserving and in need of financial support. If you have college-age students, you know the financial burden of going to school and the debt load that many students carry after college. And, even for students who are not college-bound, acquiring the appropriate training still carries a financial burden. We have talked about developing a funding program that would support other workforce education programs, but for now, that step is beyond our means.

There are a number of ways you can donate to our scholarship program. If you go to our website, www.tawwa.org, and select Scholarship from the CONTINUED PAGE 30 | executive director report

What Your Utility Needs to Know About Ebola The Water Research Foundation Shares the Facts

I

n response to utilities receiving questions from customers about Ebola's fate in the water supply, the Water Research Foundation generated and distributed the following information regarding Ebola.

Some water utilities have begun receiving inquiries regarding Ebola. Below are a few facts and resources to reinforce that Ebola cannot spread through the water supply.

The Ebola virus causes an acute illness that is often fatal with a death rate of up to 90%. Ebola virus disease first appeared in 1976 in two simultaneous outbreaks, one in a remote area of Sudan and the other in a village near the Ebola River in the Democratic Republic of Congo, from which the disease takes its name. The

current outbreak in West Africa (the first cases reported in March 2014) is the largest and most complex Ebola outbreak since the Ebola virus was first discovered.1 The current outbreak has spread through both urban and rural areas.2 Ebola is not a foodborne, waterborne, or airborne illness. The virus is transmitted to humans from wild animals and spreads in the human population through human-to-human transmission. Ebola is transmitted through direct contact with infected bodily fluids (e.g., blood, vomit, feces).1,3 The Ebola virus can only replicate within host cells. Therefore, it cannot survive CONTINUED PAGE 22 | ebola facts

Development of Water Quality Models and Innovative Tools for the San Antonio River Watersheds

BY SHEEBA THOMAS san antonio river authority

S

an Antonio River authority (SARA) recently completed a Flood Insurance Study for the Bexar County watersheds through a collaborated effort with the Federal Emergency Management Agency (FEMA), City of San Antonio, Bexar County, and other stakeholders. The Flood Insurance Study produced a set of up-to-date hydrologic and hydraulic (H&H) models and other useful watershed data that allowed SARA to conduct holistic watershed master planning (WMP) on several major watersheds including the Salado Creek, Leon Creek, and Upper San Antonio River (USAR) watersheds (Figure 1). The holistic WMPs are to integrate hydrologic, hydraulic, stream restoration, water quality, and other components into a watershed-wide planning process that can also assist in prioritizing Capital Improvement Projects (CIPs) and regulatory support.

Within the urban portions of the watersheds, several water bodies have been listed as “impaired” due to bacteria levels, dissolved oxygen, and other constituents not meeting state and federal water quality standards. While storm water runoff has been identified as a potential source of impairment, the listing of impaired water bodies is mostly based on limited monitoring data sampled at selected time intervals (mostly CONTINUED PAGE 23 | sara study

City of Waco Project Aims to Decrease Zebra Mussel Infestation in Lake Waco

T

he Russians are coming! The Russians are coming!

While this is not technically true, there are invaders from the Black Sea and Caspian Sea now overtaking lakes and reservoirs in North America.

They are unstoppable, at least thus far. Their economic impact is in the billions of dollars annually. They are about the size of a quarter.

Physical characteristics of the zebra mussels make them so difficult; they have byssal fibers that can attach to any hard surface and they reproduce at levels

up to one million per year per mussel. The optimum temperature range for their spawning is 50 to 77 degrees Fahrenheit (10 to 25 degrees Celsius).

Accidentally introduced into North America in 1988, zebra mussels, or their close relative, quagga mussels, are found in all but 15 states (summer 2014, USGS website).

In April 2009, zebra mussels were confirmed in CONTINUED PAGE 14 | zebra mussels

CONTINUED FROM PAGE 13 | zebra mussels Texas. In five years, seven lakes were reported as infested, with other lakes likely so. These lakes are in three major river basins, so downstream reservoirs are at risk for infestations.

So, what can one do?

The City of Waco (Waco) partnered with the Texas Parks and Wildlife Department (TPWD) and the U.S.

Participants unroll and move the 950-pound tarpaulin to the water.

Army Corps of Engineers (Corps) in 2011 to plan an education and outreach program at Lake Waco, the public drinking water source for about 200,000 Central Texans. The TPWD program emphasized the “CLEAN, DRAIN, DRY� approach for boaters leaving a lake. This helps with other invasive species, like hydrilla.

From Memorial Day weekend through August in 2013 and 2014, teams of inspectors were at boat ramps, beginning as early as 6 a.m. to 7 p.m. weekends and Friday afternoon, to conduct surveys using a standardized, statewide TPWD form about boating preferences, destinations and lakes. Boats from lakes with infestations were inspected for zebra mussels on boats, trailers and with water in wet wells. (It is a misdemeanor to transport invasive species from one lake to another in Texas.)

Inspectors were trained by the TPWD about invasive species, particularly methods to look for zebra mussels and their immature stage veligers. Educational materials developed by the TPWD were provided to boaters.

Local media supported the effort with several articles and news segments about the program and

zebra mussel impacts in other areas of the country.

T-shirts were designed for inspectors to help identify them to boaters.

Approximately 4,178 boaters were contacted, and 152 boats were inspected from 44 lakes that were or were suspected to be infested.

Success?

No, a barge owned by James Phillips (of Belton) was moved from that infested lake, and was not cleaned, but then launched at a private marina boat ramp (not one that was inspected) and brought zebra mussels to Lake Waco.

Fortunately, one part of the initial response plan developed in 2012 included monthly surveys of the lake and boat ramps (12 sites around the lake) and on September 26, 2014, this inspection identified zebra mussels at the private boat ramp and marina.

Subsequent inspections by TPWD confirmed the presence of the mussels and TPWD initiated DNA sampling around the lake to determine whether veligers (i.e., reproduction) were present.

Intensive assessment of the extent and area of the infestation was initiated, with scuba divers and shoreline sampling. Concurrently, representatives from Waco, TPWD and the Corps met October 3 to discuss options to reduce the impact on the drinking water source. The assessment and the DNA analyses confirmed the infested area was limited to the boat ramp and not in any other part of the lake.

Discussion at the October 3 meeting provided an approach to eradicate or reduce the infestation without chemicals or intrusive methods — covering the

area with heavy tarpaulins that would prevent oxygen or water interaction with the zebra mussels, effectively starving and/or smothering them. This approach limited the impact to indigenous species and recreational use of the lake.

Cooperation was spectacular between all participants and the urgency was palpable, since the water temperature was approaching the optimum range for mussel propagation. Within a couple days, additional research on “tarp-ing” an area was completed, a vendor was located for 30 mil polyvinylchloride sheets (Colorado Lining International) with an expedited delivery for October 20.

The nine tarps (150 X 35 feet) would be secured with nearly 1,000 sandbags, and the deeper water work was performed by American Underwater Services.

The tarps weighed roughly The nearly acre area covered with tarps 950 pounds each and secured with sandbags.

Overlapping the tarps by 5-7 feet ensured no water would pass through any abutted sheets. The tarps were continued to 10 feet on the shore, in the event of a rain raising the lake level.

Teams from the City, TPWD and Corps toiled over three days to complete the job and finished October 23, 27 days after the initial discovery of the infestation. That is fast response, to limit the infestation and the required response. In summary, 42,000 sq ft (an acre is 43560 sq ft) was covered and secured to try to eradicate this invasion.

positive economic impact for the local economy. Even purchase of the equipment and instrumentation to treat zebra mussels to keep them from clogging the water intake is more than $100,000 and then there are annual costs for chemicals.

An update will be submitted sometime next spring with the results of the eradication effort.

When will we know if this was successful?

In late February or March 2015 we will know concerning any zebra mussel presence. However, it is already a success based on the teamwork between the participating entities. Additionally, costs for this rapid response for tarpaulins were nearly $30,000 — but consider that the lake is an annual $20-30 million

Because of Ebola’s fragility when separated from its host, bodily fluids flushed by an infected person would not contaminate the water supply.4,5 Researchers believe that Ebola survives in water for only a matter of minutes. This is because water does not provide the same environment as our bodily fluids, which have higher salt concentrations. Once in water, the virus will take in water in an attempt to equalize the osmotic pressure, causing the cells to swell and burst, thus killing the virus.

To help fill these gaps and support compliance with increasing water quality (WQ) regulations, SARA conducted WQ modeling and tool developments to support the WMPs. The related WQ regulations include the Clean Rivers Program (CRP) screening and the 303(d) impaired water body listing, Texas Pollutant Discharge Elimination System (TPDES) and Municipal Separate Storm Sewer System (MS4) regulations, Texas Instream Flow Program (TIFP), Total Maximum Daily Loads (TMDL), and potential upcoming nutrient limits.

Selection and implementation of Best Management Practices (BMPs) and Low Impact Development (LID) strategies to address urban runoff pollution have become important components of the holistic WMPs. These efforts not only address existing WQ impairments and support regulatory compliance, but also guide future watershed planning, especially when substantial population growth and urbanization is forecasted. The newly created WQ models and tools help identify potential WQ impairments (locations, timing, and constituents), pollutant load reduction needed to address the impairments, and the types and numbers of BMPs needed to achieve the required load reductions.

Dynamic water quality modeling, model linkage, and development of modeling standards SARA and the LAN team have developed dynamic watershed WQ models for three major watersheds in SARB using the Hydrological Simulation ProgramFORTRAN (HSPF) a software program which was jointly

developed by the U.S. Environmental Protection Agency (EPA) and the U.S. Geological Survey. These developed models are capable of simulating watershed and instream hydrologic and water quality processes dynamically through both dry and wet periods.

SARA and the LAN team have also developed dynamic instream WQ models for three main stems using EPDRiv1, which is based upon the CE-QUAL-RIV1 model developed by the U.S. Army Corps of Engineers (USACE) but modified by the Georgia Environmental Protection Division (EPD). These models can simulate instream hydrodynamic and water quality processes in much greater spatial and temporal resolutions. SARA and the LAN team have also developed converter programs and algorithms for linking HSPF, EPDRiv1, and the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) models together.

As there are various ongoing WQ modeling efforts in the SARB, SARA developed a WQ Modeling Standards Document in December 2013 to ensure the quality and consistency of the developed WQ models. The CONTINUED PAGE 24 | sara study

The tool includes a graphical user interface to allow users to choose among the available timeseries and specify the number format needed for the exported timeseries. This tool also includes some re-engineering of the HSPF output timeseries to better handle large files. The TUT was developed, tested, and released to public through EPA’s BASINS user community on October 24, 2013, and SARA has received positive feedback from users.

The LRT was developed to determine the load reduction needed to meet screening levels specified by the users. The tool processes HSPF results and calculates flowweighted average concentrations for comparison against the screening Figure 4: Load Reduction Tool Dialog.

levels. The difference is used to develop a needed load reduction via BMP application in HSPF, and the LRT continues the iteration until all calculated flow-weighted average concentrations are meeting the screening levels within user specified tolerances. The LRT was developed to run using a graphic user interface on Windows computers. It also allows users to specify point sources that may require load reduction adjustments if the non-point source reductions are not adequate to achieve the specified screening levels.

The LRT was developed, tested, and released to public through EPA’s BASINS user community on May 9, 2014.

The SARA Enhanced BMP Tool is being developed to help select the types and number of BMPs to achieve the required load reductions identified by the LRT (or the users). The tool combines robust land surface representation from HSPF with the BMP optimization components of EPA’s SUSTAINOPT program, which optimizes the number and type of BMPs throughout a subbasin by minimizing overall costs while achieving the required target load reductions. The tool’s output includes types, numbers, and cost of BMPs as well as CONTINUED PAGE 26 | sara study

The tool includes a very extensive BMP Tool Database that contains BMPs’ data not limited to just dimensions, removal efficiencies and costs. The SARA and LAN team have conducted a substantial data collection effort to populate the database.

Figure 5: SARA Enhanced BMP Tool Dialog.

In addition to tool development, SARA and the LAN team conducted and tested several enhancements to HSPF and EPDRiv1 codes. These efforts included improved steady-state backwater solution, reduced numerical instabilities, as well as added a quasiunsteady routing algorithm option, automatic time step adjustment, in-stream BMP removal efficiency, and a GSSHA converter/importer. The enhancements

to EPDRiv1 also result in much faster runtime and more stable program execution. Additional EPDRiv1 enhancements by the SARA team also include cross section editor, HSPF WDM support in WRDB Graph and EPDRiv1 import, EPDRiv1 import tool, hydrodynamic file editor, and ability to handle water temperatures below freezing. A new BMDUtil Tool was also developed to extract/merge large EPDRiv1output BMD files, process BMD files, and statistical analyses of timeseries.

Conclusion SARA has invested substantially in the development of WQ models and innovative tools to support sustainable WQ enhancements in the SARB and hence supported its mission as “Leaders in Watershed Solutions.” These efforts have resulted in a set of very powerful and advanced WQ modeling tools that would allow SARA and its stakeholders to conduct holistic watershed master planning and evaluation of the effects of BMPs and LIDs. The developed innovative tools, which are in public domain, would benefit all WQ professionals, and SARA’s efforts are increasingly getting national attention.
