Assistance Type: OTHER WATER QUALITY - Guidnace on well activation procedures
 
Details: Hey Caitlin,
I've found some guidance on processes involved in re-activating a well once it has been deactivated/made to be an emergency well. The first and foremost items of importance would be to do coliform and nitrate samples before sending out the water to your customers. Then chemical monitoring for chronic contaminants may be required if the source has not been sampled during the monitoring period the source was used. Hope this is helpful, let me know if you wish for me to request to have wells #3 and #4 deactivated.
