f <br /> ,I <br /> • Using a properly calibrated water quality meter, measure the following indicator <br /> parameters: turbidity, pH, conductivity, oxidation-reduction potential (Eh), dissolved <br /> oxygen, and temperature. <br /> • Target values for the indicator parameters listed above are as follows: pH- stabilize, <br /> conductivity - stabilize,temperature - stabilize, turbidity NTU 10 or stabilize. A value is <br /> considered to have stabilized when 3 consecutive readings taken at one-half well volume <br /> intervals are within 10% of each other (pH stabilization =0.2 pH units). <br /> r <br /> • Notes on characteristics of the development water. <br /> • Data on the equipment and technique used for development. <br /> PRECAUTIONS <br /> Refer to the site-specific Health and Safety Plan for discussion of hazards and preventive <br /> measures during well development activities. <br /> REFERENCES <br /> r Fletcher G.
