The drogues were designed to detectcurrent direction and velocity. Eachdrogue consisted of four 51 in.2 sheetmetal fins (6 in. wide by 8.5 in. high)attached at right angles and connectedto styrofoam flotation material by athin fiberglass centerpost (see Figure2-2). The styrofoam permitted the finsto be suspended 18 in. below the watersurface. Drogues were marked withsmall triangular flags for observationand identification.

Drogues were released on either flood Figure 2'2 Dr°Sueor ebb tide. Positions were fixed by maneuvering the project boat alongside thedrogue and recording latitude/longitude coordinates using a Mieco C-Scout LoranC. Positions, taken at intervals of 15-20 min, were recorded until the droguespassed the proposed plant intake site or were unable to proceed any farther (e.g.,grounded in shallow water). Because of the malfunctioning of the Loran C duringdrogue study No. 4, positions were fixed by visual observation. Although not asaccurate as the Loran C coordinates, this procedure provided useful data. Thetrajectories produced were similar to those of drogue study No. 2 (also releasedduring ebb tide).
Release points were chosen based on the location of possible spills and bypasses.Three floodtide release points were used: (1) the eastern main pier of the Tacony-Palmyra Bridge, (2) sampling station No. 4, and (3) near the Pompeston Creek-Delaware River confluence. The bridge is an obstruction to boat traffic and a

2.2 Selection of Water Quality Parameters
Water quality parameters were specified primarily to address any substance thatcould be present in excess of current drinking water standards, with particularattention given to those with possible human health implications. The criteriareferenced throughout this report were taken from USEPA National PrimaryPrinking Water Regulations and New Jersey Department of EnvironmentalProtection Maximum Contaminant Levels (MCLs) for Hazardous Contaminants in
Drinking Water (A-280). *_ *pt|U r< ft* . * fc-
The priority for the laboratory analyses of water quality parameters was setaccording to the importance of each constituent and the amount of data needed fora reasonable evaluation. Laboratory parameters were analyzed on grab orcomposite samples collected during intensive and nonintensive surveys as shown in

What's the bottom tine? How much will the L*TJ ^ snouu we worry now about a waterproject cost? T * source for the future?
It's important to keep the cost as low as possible.Water is one of the best bargains there is. And wewant to keep it that way.
In 1992, the average New Jersey-American customer paidabout $261 a year for water service. Although we cannot estimateexact prices for the future, it is safe to say that the cost of waterwith or without the Tri-County Project will be significantlyhigher. Continual declines of the water level in the PRM aquiferhave already forced us, and many other area suppliers, to spendseveral million dollars just over the last five years to drill newwells, make existing wells deeper, and clean water from wellsthat became contaminated. We could continue these piecemealimprovements, but it is unlikely they would provide more than ashort-term solution to the area's water shortage.
Current water supplies cannot continue tosupport forever the demands we've placed onthem. Not only could some wells dry up from
overuse, but others could become contaminated bysurface materials or by natural salt water movement.
As the threat of running out of water becomes moreserious, we may all have to change the way we use water— not just in the summer months, but all year round.New Jersey-American Water Company believes thatpeople should not have to change their lifestyles due to alack of water, especially when there are alternativesavailable. We feel strongly that the Tri-County WaterSupply Project is the best alternative.

-What is the Tri-County WaterSupply Project?
The Tri-County Water Supply Project is a publicworks system being built by New Jersey-AmericanWater Company to bring additional water to areas of
Burlington, Camden and Gloucester counties.
Why is the project necessary?The region's primary water supply is rapidly beingdepleted. The N.J. Department of EnvironmentalProtection and Energy (DEPE) has designated the tri-
county region as a "critical area" and has called for theidentification and development of alternative water supplies.The Tri-County Water
How will the Tri-CountyWater Supply Project work?
Water will be taken from the Delaware River,treated at a state-of-the-art filtration plant in Delran,and then brought to water utilities in the three
counties through as much as 40 miles of pipeline.
Once the project is in operation, will SouthJersey be the only area to receive its drinkingwater from a river source?
No. Many areas throughout the nation have beenusing rivers as safe drinking water sources for years.In the region, many communities in both New Jersey
and Pennsylvania use the Delaware River as their primarysource. New York City uses
