The nitrate MCL is different for community and non-community water systems. The MCL for community systems is 10 mg/L but for non-community systems is 20 mg/L. Non-community systems with a nitrate level above 10 mg/L are required to post public notice, but they do not incur a violation unless they exceed 20 mg/L.

No. KHEL's database date stamps all sample paperwork with a Sunday collection date because it identifies Sunday as the first day of the week. The lab is suggesting you collect within the week following the Sunday date, not the Sunday itself. Please collect all samples as soon as you can and return them as instructed.
Excluding asbestos, all samples required under the Phase II/V Rules are collected from each point-of-entry to the distribution system, commonly referred to as a POE. The POE is a location after which raw water has been treated but before treated water has entered the distribution system. Each POE sample location should be marked by a metal tag stamped with an eight-digit identification number. The sample paperwork you receive from the lab will always specify the collection site.
You must notify your customers of the violation by distributing public notice. The envelope containing your notice of violation letter also contained the forms you need to fulfill this requirement. The paperwork you received includes a public notice template with some mandatory information already filled in for you, and a Certificate of Delivery. The public notice must be distributed as described in your letter. After you issue the notice, the Certificate of Delivery and a copy of the notice you distributed must be sent to KDHE within ten days.
No. The Public Water Supply Section does not have access to KHEL reports. If you would like to request a copy of your sample results, please contact the lab at 785-296-1620.
