Operation studies of the Rio Grande reservoir system <br />for the 70-year period 1900-1970 indicate water shortages for the <br />750,000 acres of land alloted irrigat:ion water rights by the court <br />order arising from the Lower Rio Grande Valley Water Case would <br />occur 70 percent of the time, with the average annual shortage <br />approximately 253,000_ acre-feet. Thus, maintaining the current <br />level of irrigated agricultural acreage in the Valley, as well as <br />providing vit:ally-needed supplies for additional prime irrigable <br />lands, requires supplemental supplies over and above Rio Grande <br />supplies which are "fixed" by International Treaty and court ad- <br />judicated decree. Additionally, existing water quality problems, <br />storage and conveyance system inadequacies, and drainage problems <br />must be resolved. <br /> <br />Problem Area 4.

Water Supply and <br />Quality Problems in Small Cities and Rural Communities as a Conse- <br />quence of Implementing the 1974 Safe Drinking Water Act; (P.L. 93-523). <br /> <br />An assessment was made by the Texas Water Development Board of <br />all of Texas' public water systems which could not comply with the <br />Environmental Protections Agency's (EPAis) Interim Primary Drinking <br />Water Standards of the Safe Drinking Water Act of 1974, (P.L. 93-523). <br />This assessment used water quality information obtained from the records <br />of the Texas Department of Health Resources as of May 14, 1976. Results <br />of the assessment indicated that a total of approximately 600 public <br />water systems in t:he State will be in violation of the EPA Interim <br />Primary Standards with the majority of these being unable to meet the <br />maximum standards set for the contaminant fluoride with many in <br /> <br />62 <br /> <br />.. - <br /> <br />1 <br /> <br />\ . <br /> <br />", "-.. .. <br />
