A.The reporting terms presented in Table 2 of § 2.14(A) of this Part are intended to provide clear, effective, and consistent communication between water quality professionals and system owners. Analytical laboratories may consider the use of these reporting terms as an additional option (beyond reporting numerical values). The reporting terms reflect a comparison of the detected levels to the existing limits for a given constituent. The constituent detected, level of detection, and corresponding reporting terms shall be used to determine the appropriate response. Reporting terms and recommended responses for all constituents shall be as follows:

B.When the analytical result for a constituent is reported as “Present” with respect to MCLs and HAs as described in this section, the licensed interpreter shall:

1.Notify Department via a copy of the analytical report or by electronic data submission within fifteen (15) days of completion of analysis.

2.Notify the system owner of the constituent(s) present and what, if any appropriate response is needed.

C.When the analytical result for a constituent is reported as an “Action Level” or as “Elevated” with respect to MCLs and HAs as described in this section, the licensed interpreter shall:

1.Notify the Department,

2.Notify the system owner of the constituent(s) present and the appropriate response suggested or needed.

D.When the analytical result for a primary constituent is reported as “Extremely Elevated” with respect to MCLs and HAs as described in this section, the interpreter shall:

1.Immediately notify the Department,

2.Immediately notify the system owner of the constituent(s) and level(s) present and appropriate responses needed.

A.Licensed interpreters, and/or Local Building Officials shall determine appropriate corrective actions based on the reported level(s) of the constituents in the untreated water from a private water system. Additional testing may be required to evaluate whether a proposed treatment system is the most effective means to remove a constituent that is potentially hazardous to health.

B.Corrective actions are categorized as follows:

1.Immediate corrective actions shall be used upon the discovery of well water that is at the elevated or extremely elevated levels. These levels shall require minimizing or eliminating consumptive use and ingestion of the water. Immediate corrective actions shall include, but are not limited to: the use of bottled water or water from a different potable source for consumptive purposes and may require the discontinued use of the contaminated well water for other household purposes.

2.Short-term corrective actions shall be instituted in conjunction with immediate corrective actions associated with the highly elevated or hazardous levels, in order to provide a potable supply of water. Short-term corrective actions shall be an interim step while long-term corrective actions are considered. Short-term corrective actions may include, but are not limited to use of bottled water, installation of a point-of use or point-of entry treatment system.

3.Long-term corrective actions shall be instituted after a study of the source and nature of the constituent(s) present has been completed. Long-term corrective action options include: acquiring a new source, installation of a point-of use or point-of entry treatment system, or connection to public water supply.
