TABLE 7.1 Cont'd WATER QUALITY SU~>IMARY MURGI~~LLA ROAD CROSSING - Water is present at the site throughout most o:(' the year, however, flov; vlill only be present only 6-8 months per year. A gauge board has been present at the site for estimation of flow since December 1979. The water quality at the site is fairly constant with reasonably high conductivity and nutrient levels throughout the year. Some uranium concentration fluctuation have been observed. COOPERS CREEK, NT. BORRADAILE - Water is at the site for most of the year, and flows 8-10 months of the year. The water is clean and clear with little change in water quality except for a slight nutrient increase towards the end of the dry season. KOONGARRJl.. AREA 1237 438 239 AR~Y CREEK - SITE 2A - This is a small creek which conta1ns water 9-12 months of the year, by virtue of its source on the escarpment sandstones. It contains little susoended solids and its conductivity is low L at all times. Little uranium is present, hmvever, radium is often present in waters indicating radioactive content in groundwater host rocks. NOURLANGIE ROCK - Water is present at this site on Koongarra Creek for only 4-5 months of the year. Quality is good and consistent with continual flushing. Concentrations of uranium observed are very low. NOURLANGIE CREEK - JIM JIM ROAD CROSSING - This site contains water for 9-10 months of the year. The site shows the expected slight increase in conductivity, nutrients and carbon as the water dries up and other than that, quality is constant, consistent with streru~ flushing. The site does however, show an irregular fluctuation in pH and resulting zinc fluctuation as the site dried up in the 1979 dry season and as water again flowed in the 79/80 wet season.
