Drainage Report to General Meeting
May, 2010

The initial water testing was done on April 8, 2010, the first of four tests scheduled for this year. Sites tested were the ocean, the lagoon in the middle of town, the lagoon on the north side of town, and the city water. The ocean water tested clean, suitable for it's everyday use. Both lagoons tested positive for fecal coliform, but with levels below the acceptable safe limit. The city water tested clean for general use, but not necessarily for use as drinking water.

The samples were sent to La Penita and forwarded to a lab in Tepic. When Roy McLean takes the samples, he also records relevant environmental factors including the presence of fish, any noticeable odor, and the general condition of surrounding vegetation.

The following chart was obtained from a website that reports of the water conditions of Lake Chapala, inland Mexico. The website explains the levels acceptable in Mexico but the chart below reflects the levels used by the USA. For more information, please refer to www.amigosdelago.org/news/ColiformTesting-e.htm .

Fecal coliform levels from Amigos' tests were reported as follows, per 100ml:

Ocean < 1.8
Lagoon in the middle of town 640
Lagoon on the north side of town 350
City water < 1.8
