Results of the monitoring are to be used to determine whether water treatment at the [treatment plant name] is sufficient to adequately remove Cryptosporidium from your drinking water. We are required to complete this monitoring and make this determination by [required bin determination date]. We 'did not monitor or test' or 'did not complete all monitoring or testing' on schedule and, therefore, we may not be able to determine by the required date what treatment modifications, if any, shall be made to ensure adequate Cryptosporidium removal. Missing this deadline may, in turn, jeopardize our ability to have the required treatment modifications, if any, completed by the deadline required, [date]. For more information, please call [name of water supply contact] of [name of water supply] at [phone number]."(b) The special notice for failure to determine bin classification or mean Cryptosporidium level shall contain the following language: "We are required to monitor the source of your drinking water for Cryptosporidium in order to determine by [date] whether water treatment at the [treatment plant name] is sufficient to adequately remove Cryptosporidium from your drinking water. We have not made this determination by the required date. Our failure to do this may jeopardize our ability to have the required treatment modifications, if any, completed by the required deadline of [date]. For more information, please call [name of water supply contact] of [name of water supply] at [phone number]."(c) Each special notice shall also include a description of what the water supply is doing to correct the violation and when the supply expects to return to compliance or resolve the situation.Mich.
