7. PROJECT DESCRIPTION:

A- OBJECTIVE AND SCOPE; -

The objective is to determine the current quality of groundwater used as the sole source of potable supply for residents of Pomona Oaks. The residents of this housing development (approximately 200 homes) depend on private wells for potable water. Figure 1 depicts those homes in this development to be sampled.

B. DATA USAGE:

The data will be used to determine whether the potable water wells of additional homes in Pomona Oaks are contaminated with volatile organics. This effort will focus on those homes in the western part of the subdivision which have never been sampled. Some homes located around the perimeter of the subdivision will also be sampled. Thus, it will be possible to ascertain if there is an immediate health threat to residents of these homes.

C. WELL SAMPLING:

Groundwater samples shall be collected from sixty-seven (67) domestic potable water supply wells and delivered to the Region II EPA Laboratory for analysis. All !hXief*TiU b? ana^fe? for volatile organics, and three (3) samples will be analyzed additionally for priority pollutants (i.e., semivolatiles and metals). Appendix 1 lists the groundwater sampling points for this evaluation. B v

000551.

«

One set of travel blanks for the semivolatiles and metals, ana two sets of travel blanks for volatile organics will also be included. Each sample ahall be collected in accordance with the procedure set forth in Section 11.

11- SAMPLING PROCEDURES:

Each domestic potable water supply well shall be sampled a water faucet located as close as possible to the

ETJ"! Hi l\." possible, the selected faucet location will be one which receives water from the pumping well £ a t e r f " 8 t r e «ted by any equipment installed on the r t l t l ?P y ?y6ten- Where ^is is not possible, such treatment equipment will be turned off if permissible. All treatment systems 'on line' between the pumjing w^ll and sampling point will be noted, including softening iron removal, turbidity removal, disinfection, pH adjustment and home carbon filters. Filter screens present on kitchen faucets will be removed wiere possible aeiaUon of*^108 f?' V°3atile panics to minimize the aeration of the collected sample.

Each domestic well -will be pumped in order to evacuate of the standing water from the plumbing and water

*•=-" "8uPPl.y well prior to collecting the groundwater sample. Any water storage tanks between the pumping well And sampling point will also be evacuated prior to sampling. These pumping and evacuation procedures will be adhered to where practical based upon field evaluation. At Pomona Oaks, these procedures will be accomplished by running the kitchen tap or outside spigot for fifteen minutes prior to sample collection. All bottles/containers to be utilised for sample collection have been specialty cleaned by the distributor, I-Chem Research', Inc. of California. Sample containers will he thoroughly rinsed with the water to be sampled before actual sample collection. Collected samples will be individually labeled in the field and stored in coolers with ice packs until they are delivered to the Region II EPA Laboratory. Preservatives will be added to the required samples in the field immediately following the collection of the samples.

12. SAMPLE CUSTODY PROCEDURES:

EPA Chain of Custody will be maintained throughout the monitoring program as per: TAT SOP on sample handling, Sampling Container Contract specifications, and EPA Laboratories SOP.

o 13• DOCUMENTATION. DATA REDUCTION AND REPORTING:

Documentation: Field data will be entered into a bound notebook. Field notebooks, chain of custody forms, and lab reports will be filed and stored as per TAT Document Control Systems.
