Lake Hot Stuff area of the province

1) For map 2 of the Lake Hot Stuff area of the province the following well chemistry has been determined:

Well Site                                                                     U ppm                        Radon B/l

A                                                                                             .004                             500

B                                                                                             .003                             628

C                                                                                             .002                             899

D                                                                                             .019                             3246

E                                                                                              .030                             4444

F                                                                                              .151                             5798

G                                                                                             .198                             7729

H                                                                                             .224                             10000

I                                                                                               .025                             2000

J                                                                                               .003                             4587

K                                                                                             .009                             3789

L                                                                                              .008                             2290

M                                                                                             .007                             1100

N                                                                                             .018                             2659

O                                                                                             .019                             2987

1. a) Plot the numbers beside each well site on the map for example .N .018 U

2659 Rn

1. b) The limit for uranium in water has been determined to be 0.019 ppm. Draw an all inclusive polygon (or contour) around all of the well sites greater than the acceptable limit. (Use pencil or coloured pen).

1. c) The limit of radon that is considered safe is 2000 bacquerels per litre. Draw an all inclusive polygon (contour) around all of the well sites greater than the acceptable limit. (Use a different colour pencil or coloured pen than used for uranium).

1. d) Which of the polygons (contours) is larger? Why might this be the case? Do the polygons correspond to any particular rock type or types?

1. e) There are numerous building lots available in this area. Where would you build your house and explain the reasons for your choice.
