Our water testing kit has finally arrived in the mail. So far, we had collected 8 water samples.

The full list of samples is below:

1. Phipps Run stream at GPS location N 40°26'16.1" W 079°56'45.60" (June 18 2013)
2. Panther Hollow stream at GPS location N 40°26'11.6" W 079°56'43.40" (June 18 2013)
3. Presque Isle, Lake Erie at GPS location N 44°40'47.8" W 081°01'88.50" (July 5 2013)
4. East Springfield, well water, at GPS location N 42°08'67.8" W 080°08'26.50" (July 6 2013)
5. East Springfield, Lake Erie, at GPS location N 42°00'23.00" W 080°26'46.40" (July 6 2013)
6. East Springfield, Elk Creek, at GPS location N 42°01'32.00" W 080°22'48.70" (July 6 2013)
7. East Springfield, Elk Creek, at GPS location N 41°59'51.60" W 080°1907.40" (July 6 2013)
8. Ocean City, Maryland

(Position formats for all sites are hddd°mm'ss.s" , Map Datum WGS 84, Map Spheroid WGS 84)

We then took these 8 samples and tested them for: dissolved oxygen, chlorine, nitrate, phosphate, turbidity, ammonia nitrogen, and pH.
