Assistance Type:	WATER QUALITY ALERT RESPONSE
Reasons:	Nitrate

Details:	Spoke to Jim Foster - the operator at Colorado Lake COOP regarding the nitrate sample results being a little bit over half of the MCL. I told him that at this time he does not need to go to quarterly sampling due to the the previous avg. staying around the same range. Mentioned it to him that if the nitrate level does get close to 7-8 then more than likely we'll require them to go on quarterly monitoring again.
