<br />a mix of monies derived ITom the state's general fund, <br />permit fees and federal grants. More than $9 million is <br />allocated to water-quality management in this state. <br /> <br />Major Challenges and Key <br />Water-Quality Issues <br /> <br />Growth <br />Growth and development threaten to degrade many <br />of Colorado's high-quality waters. In particular, <br />rapid urbanization in mountain recreational areas <br />brings new threats associated with storm-water <br />runotI soil erosion. encroachment upon riparian <br />areas, increast'd nurrient concentrations and habitat <br />degradation. It is important that development be <br />well-planned, and that impacts resulting fi'om <br />changing land uses, increased population and <br />increased municipal water usage be factored into <br />government decisions at all levels to ensure that <br />valuable water resources are protected and pre- <br />st'rved. The Front Range area along Colorado's <br />Eastern Slope is also experiencing pressures from <br />rapid urban growth and development. Nearly every <br />Front Range river is impacted or impaired. <br /> <br />Restoration of Impaired Water Bodies- <br />Developing and Implementing Total <br />Ma"imum Daily Loads <br />The Federal Clean Water Act requires states to iden- <br />tit), watt'rs not meeting water-quality standards <br />designed to protect aquatic life, recreation, drinking <br />water supply and agricultural uses. Once the state <br />identifies these waters, it is required to analyze the <br />causes of water-quality problems and allocate <br />responsibility for controlling pollution. A total maxi- <br />lIlum daily load must be established to specify the <br />allowable amount of any specifiC pollutant that ..1 <br />water body can receive without violating water- <br />quality standards. The complexity of this efrort <br />varies in relation to the water body and the sources <br />of pollurancs under consideration, To encourage <br />cooperation and volulltary actions, and because <br />additional concrols on point and non point sources <br />of pollution may be required. participation from all <br />stakeholders interested in the water body is desir- <br /> <br /> <br />able. Colorado currently lists 85 water bodies that <br />require the development of 198 total maximum <br />daily loads. This workload is expected to increase <br />dramatically within the next year based on monitor- <br />ing and assessment work now underway. <br /> <br />Drinking Water Quality-Source Water <br />Protection Program <br />Changes to the Safe Drinking Water Act in 1996 <br />require that all states perform a "source water <br />assessment" far public drinking water supplies in an <br />effort to protect source (raw untreated) water from <br />contamination. The Source Water Assessment and <br />Protection Program (SWAP) is intended to prevent <br />water pollution and fits well with the watershed <br />concept. The program requires four steps: <br /> <br />delineation of the source water area for each <br />public water system <br /> <br />inventory of possible sources of contamination <br />within the source water area <br /> <br />an analysis of the susceptibility of the public water <br />system to each of the contaminants or con. <br />taminant sources identified in the inventory <br /> <br />publication of the results of the delineation, <br />inventory and susceptibility analysis <br /> <br />foot contains 7.5 ga/fo <I ",eighs a60ut 6'lA ?ounds. <br />f'Js of Water a(\ "'-\Co ~oot per seco/} <br />c.lj.v d fl. aunt SUffic' <br />~e ows is an -a.{'\I lent to supply tWO to three families for a year. <br />,0 <br />o <br />VV ..~e <br />ater flowing at a \' <br />
