It became muddy opaque water and has not cleared at all to date 16 July. Rachel was previously a clear spring in a vent ~10m diameter, in the Government Gardens, Rotorua. </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Prior to this event it had always been clear, alkaline and boiling or almost boiling for >150 years. It is uncertain if this present change is entirely natural as it is pumped for <12 hrs each day to supply hot water to a bathing complex nearby. This pumping causes a waterlevel change of ~2m height daily.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>When left unpumped for a year or two in late 1980s, Rachel overflowed at ~12 lps steadily for many months.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Ashley Cody, Rotorua</FONT></DIV></BODY></HTML>
