Cooperative Extension Service Hawaii’s Pollution Prevention InformationDec. 2000HAPPI-Home 2One way to help identify potential sources of waterpollution around your home is to make a map show-ing the features of your house and yard. Although yourproperty may have physical features that you cannotchange, there may be things that can be done to mini-mize risks.To make your map you need: a clipboard or note-book, a pencil, and page 3 of this worksheet. The mapyou create will be an aerial view—the way your houseand yard would look if you took a photo of it from theair. A sample map is provided on page 2. Your land titleor lease documents may also contain useful maps. Theamount of detail you put in your map will depend onthe map(s) you already have and the time and resourcesyou have available, but be sure to include the followingfeatures:• property boundaries• garden areas and flower beds• roads• ponds, streams and drainage ditches• any paved areas like driveways and patios.Some management practices and site characteris-tics can have major effects on water quality. As you sur-vey your property to make your map, be especiallywatchful for the following and mark their location onyour map:• drinking water well or catchment system if you donot have municipal water service• septic system or cesspool if you do not have munici-pal sewer service• abandoned wells• places where you store, use, or dispose of potentiallyhazardous household products such as fertilizers, pes-ticides, gasoline, oil, paints, and solvents• large paved or concrete-covered areas.Try to include as much information as possible onyour map. Show the approximate size of flower beds,gardens, driveways and patios and their distances fromeach other. A sketch will be adequate for beginning theplanning process. Having a more accurate map will al-low you to calculate the areas of gardens, lawns, andother features, which can later be useful in planning thebest ways to reduce pollution hazards around your home.After making a map of your property, you can useit to complete HAPPI-Home 1, Water quality aroundthe home, which will direct you to the other HAPPIworksheets that fit your situation.This HAPPI document was adapted by Michael Robotham, Carl Evensen, and Linda J.
