Th 1 b ~ 1 ' ;, ' ~ ' 1 ~ ~ ' r.r .;... , ere are a _arge num er o'- san'.[) L.g po~nt" ~nc_ucea ~n "a~er Division's water qual~ty monitoring progra~~e in the Alligator Rivers ~egion. They consist of points used for the two types of monitoring carried out; regional and regulatory. 5.1 Recional Monitoring The regional :noni tor ing programme was based upon the .iO,ugust 1978 Jabiru workshop (see Appendix A). Nineteen sites were specified, primarily on Magela Creek and tributaries entering close to the Ranger site, with others close to proposed and Koongarra sites. Additional sites have since been added to cover the Nabarlek and proposed Koongarra sites more fully, and also the regional town. The sa~pli~g network is described in Table 5.1. This shows a total of 30 sites used for routine regio~al Donitorins (33 listed, 2 discontinued- RSP 391B and 1236, and RPl not sa~pled). A complete rationale and history of these sites are shown in Table 5.2, and locations are show~ on maps 4 and 5. Geogra?hical locations are described in Table 5.3 5. 2 Regulatory ~loni taring This is a less structured progran'me than the regional progra~~e and is aimed at problem areas or possible problem areas. The chemical analysis (range of parameters) and San'pling frequency are tailored to the s9eci:ic ~onitoring site. Exa~ples are weekly pH and physical checks, monthly bacteriological analysis and quarterly pesticide analyses. Many sites are monitored only for short periods o: time, intermittently, or locations c~anged. This is done as site works are carried out or completed, facilities are put into use, occur~ence of localised problems, duri~g first flushes, or spot checks. A list of regulatory monitoring sites currently in use is shown in Table 5.4. This type of monitoring is carried out for a two fold reason. Firstly is Water Division's responsibility under the N.T. Controller of Waters Act, and secondlv within responsibilities, - under the Uranium Mining (Environmental Control) Act as a supervising authority. All further disc~ssion in this report will be concerned with ~he regional rather than regulatory monitoring. This is done because ~ore com?lete, long term descriptions of water bodies are achieved in the regional monitoring, rather than the problen oriented regulatory role.
