1. (1) Issues to be Considered.

   The selection, development, and operation of a public drinking water source must be done in a manner that will protect public health and assure that required water quality standards, as described in Rule R309-200, are met.

2. (2) Communication with the Division.

   Because of the issues described in Subsection R309-515-4(1), engineers are advised to work closely with the Division to help assure that sources are properly sited, developed, and operated.

3. (3) Number of Sources and Quantity Requirements.

   Community water systems serving more than 100 connections shall have a minimum of two sources, except where served by a surface water treatment plant. For each system, the total developed source capacity shall equal or exceed the peak day demand of the system. Refer to Section R309-510-7 of these rules for procedure to estimate the peak day demand.

4. (4) Quality Requirements.

   In selecting a source of water for development, the designing engineer shall demonstrate to the satisfaction of the Director that the source selected for use in public water systems are of satisfactory quality, or can be treated in a manner so that the quality requirements of Rule R309-200 can be met.

5. (5) Initial Analyses.

   1. (a) each of the primary and secondary inorganic contaminants listed in Rule R309-200, Table 200-1 and Table 200-5, excluding Asbestos unless it would be required by Subsection R309-205-5(2);
   2. (b) Ammonia as N; Boron; Calcium; Copper; Lead; Magnesium; Potassium; Turbidity, as NTU; Specific Conductivity at 25 degrees Celsius, micro mhos/cm; Bicarbonate; Carbon Dioxide; Carbonate; Hydroxide; Phosphorous, Ortho as P; Silica, dissolved as SiO2; Surfactant as MBAS; Total Hardness as CaCO3; and Alkalinity as CaCO3;
   3. (c) pesticides, PCBs, and SOCs as listed in Subsection R309-200-5(3)(a), Table 200-2 unless the system is a transient non-community PWS or, if a community PWS or non-transient non-community PWS, has received waivers in accordance with Subsection R309-205-6(1)(f). The following six constituents have been excused from monitoring in the state by the EPA, dibromochloropropane, ethylene dibromide, Diquat, Endothall, glyphosate and Dioxin;
   4. (d) VOCs as listed in Subsection R309-200-5(3)(b), Table 200-3 unless the system is a transient non-community PWS; and
   5. (e) radiologic chemicals as listed in Subsection R309-200-5(4) unless the system is a non-transient non-community PWS or a transient non-community PWS.
   6. (f) Every analysis shall be performed by a certified laboratory as required by Section R309-205-4 Specially prepared sample bottles are required.

   New drinking water sources, unless otherwise noted in Subsections R309-515-4(5)(a) through (f), shall be analyzed for:

6. (6) Source Classification.

   1. (a) surface water or groundwater under direct influence of surface water which requires conventional surface water treatment or an approved equivalent; or as
   2. (b) groundwater not under the direct influence of surface water.

   Subsection R309-505-7(1)(a)(i) provides information on the classification of water sources. The Director shall classify each existing or new source as either:

7. (7) Latitude and Longitude.

   The latitude and longitude, to at least the nearest second, or the location by section, township, range, and course and distance from an established outside section corner or quarter corner of each point of diversion shall be submitted to the Director before source approval.
