• groundwater quality parameters (temperature, pH, specific conductance, and turbidity) <br /> have stabilized over three consecutive readings. <br /> If the above criteria are not able to be achieved, due to well dewatering or other observed <br /> restrictions (such as improper construction or design of the monitoring well), the reason will be <br /> communicated on the well development record form and the condition will be reviewed by a <br /> license professional geologist. The professional geologist will ultimately make the decision as to <br /> the development completion of each well. <br /> At the completion of well development, all non-dedicated equipment (i.e. surge block, bailer, <br /> and/ or pumps) shall be decontaminated prior to use in the next well. Decontamination should <br /> consist of either pressure washing or scrub in non-phosphate solution followed by two tap water <br /> rinses. <br /> 2.2 Documentation <br /> The following data shall be recorded for development: <br /> • well designation; <br /> • date of well installation; <br /> • date of development; <br /> • static water level before and after development; <br /> • quantity of standing water in well and annulus (30-percent porosity of saturated annulus <br /> assumed for calculation) prior to development; <br /> • depth from top of well casing to top of sediment inside well, before and after <br /> development; <br /> • groundwater parameter and turbidity readings; <br /> • type and size/capacity of pump and/or bailer used; <br /> • typical pumping rate; <br /> • estimate of recharge rate; and <br /> • quantity of water removed and time for removal. <br /> This information shall be documented on the Well Development form provided below. <br />
