 90th percentile value: 90% of the samples were at or below this value. EPA considers the 90th percentile value the same as an "average" value for other contaminants. Lead and copper are regulated by a treatment technique that requires systems to control the corrosiveness of their water. If more than 10% of tap water samples exceed the action level, water systems must take additional steps. The test results shown above are from 2015. The next monitoring will occur in 2016.

"City of Watauga's Unregulated Contaminant Monitoring Rule (UCMR 3) Information" 
Data gathering to determine if more regulation needed 
Water utilities in the United States monitor for more than 100 contaminants and must meet 91 regulations for water safety and quality. But should other contaminates be regulated? The 1996 Safe Drinking Water Act amendments require that once every five years EPA issue a new list of no more than 30 unregulated contaminants to be monitoring by public water systems. This monitoring provides a basis for future regulatory actions to protect public health. The third Unregulated Contaminant Monitoring Rule includes assessment for 21 chemical contaminants, 7 hormones and two viruses. The virus testing did not impact the City of Watauga. This testing was limited to small groundwater systems that do not disinfect. UCMR benefits the environment and public health by providing EPA and other interested parties with scientifically valid data on the occurrence of these contaminants in drinking water. 
Health information is necessary to know whether these contaminants pose a health risk. Public water systems will sample for these contaminants for four consecutive quarters from 2013 to 2015. City of Watauga's sampling occurred from February 2014 through November 2014.

Common Sources of Substances 
Detections 
Naturally-occurring elemental metal; used as vanadium pentoxide which is 
a chemical intermediate and a catalyst 
Naturally-occurring element found in ores and present in plants, animals 
and bacterial; commonly used form molybdenum trioxide used as a chemical reagent 
Naturally-occurring element; historically, commercial use of strontium has 
been in the faceplate class of cathode-ray tube televisions to block x-ray emissions 
 Naturally-occurring element; used in making steel and other alloys; 
chromium-3 or -6 forms are used for chrome plating, dyes and pigments, 
leather tanning, and wood preservation. 
Total Chromium, the sum of chromium in all its valence states, is already regulated in drinking water. As part of 
UCMR 3, EPA requires testing for Total Chromium in the same samples used to test for Chromium 6, which is on the 
UCMR 3 list. The value differs from what is listed in the other table because of different sampling periods. The MCL for 
EPA's current total chromium regulation was determined based upon the health effects of Chromium 6.

 The City of Watauga had an estimated water loss of 40,869,972 gallons (6.17) % of water purchased).

1 Because Fort Worth historically has had low levels of metals in its water, the Texas Commission on Environmental Quality (TCEQ) 
requires this monitoring occur only once every six years. The test results shown above are from 2010. The next monitoring will occur in 
2016. 
2 Because Fort Worth historically has had low levels of radionuclides in its water, TCEQ requires this monitoring occur only once every 
three years. The test results shown above are from 2013. The next monitoring will occur in 2016. 
3 Turbidity is a measure of the cloudiness of water. It is monitored because it is a good indicator of the effectiveness of the filtration 
system.

treatment technique requirements for disinfection by-product precursors.

Microorganism testing shows low detections in raw water 
Tarrant Regional Water District monitors the raw water at all intake sites for Cryptosporidium, Giardia Lamblia and viruses. The source 
is human and animal fecal waste in the watershed. The 2015 sampling showed low level detections of Cryptosporidium, Giardia 
Lamblia and viruses that are common in surface water. The table below indicates when detections were found in each raw water 
source. 
Cryptosporidium and Giardia Lamblia monitoring is done monthly. Virus monitoring is performed four times a year in January, March, 
July and September. Viruses are treated through disinfection processes. Cryptosporidium and Giardia Lamblia are removed through a 
combination of disinfection and / or filtration.

TCEQ accesses raw water supplies for susceptibility 
Fort Worth uses surface water from Lake Worth, Eagle Mountain Lake, 
Lake Bridgeport, Richland Chambers Reservoir, Cedar Creek Reservoir, 
Lake Benbrook and the Clear Fork Trinity River. 
 Fort Worth owns Lake Worth. The U.S. Army Corps of Engineers is responsible for Benbrook Lake. The other four lakes are owned and 
operated by Tarrant Regional Water District. The Texas Commission on Environmental Quality completed an assessment of Fort Worth's source waters. TCEQ classified the risk to our source waters as high for most contaminants. 
 High susceptibility means there are activities near the source water a or watershed make it very likely that chemical constituents may come into 
contact with the source water. It does not mean that there are any health risks present. Tarrant Regional Water District, from which Fort Worth purchases its 
water, received the assessment reports. For more information on source water assessments and protection efforts at our system, contact Stacy Walters at 817-392-8203.

   La disfunción eréctil (la mal llamada "impotencia") se define como la incapacidad para obtener una erección suficiente para completar una relación sexual satisfactoria. Esto incluye tanto la imposibilidad de conseguir una erección (disfunción eréctil total), como las dificultades para mantenerla durante un cierto tiempo o en determinadas posturas (disfunción eréctil parcial).
