Assistance Type:	WATER QUALITY ALERT RESPONSE
Reasons:	Coliform

Details:	I spoke with Mike Stone about the positive total coliform water sample result, and mentioned that one "repeat" distribution sample collected from the same tap or one nearby is required, as well as one "triggered" source sample from each active well, within 10 days. This now includes the new Well #11 that was installed, in addition to Well #8. Mike said that Well #6 has currently been taken offline to the system because there is a broken line from that well to the Reservoir; that well has been inactivated at this time. Mike added that the repeat and triggered source samples will be collected.
