Fix malfunctioning sprinklers and faucets Water only when necessary and for appropriate amounts of time Hazardous and non-hazardous materials discarded in unprotected dumpsters Creates danger to sanitation workers emptying the dumpsters. If these materials escape, they are transported through the soil or a storm sewer to Waller Creek where they can severely affect aquatic life and render water unusable for drinking or recreation. Restrict dumpster access to trained personnel Assure drain valves are functional Protect all dumpsters from rainfall with either covers or overhead roofing All materials in dumpsters should be bagged or in containers Dirt, oil buildup, and accumulated debris cleaned from walkways and drives Cleaning agents can provide nutrients that promote the growth of algae. The blooms deplete sunlight available to aquatic life. Then, as it decays, the algae use up the oxygen available for aquatic life to survive.
Fertilizers contain large amounts of nitrogen and phosphorus- primary nutrients for algae.
As it decays, the algae use up the oxygen necessary for aquatic life to survive. Some fertilizers also release ammonia, which is toxic to fish. Limit the amount of fertilizer used. Also seeps into groundwater and contaminates drinking water, and destroys soil by killing essential organisms from microbes to earthworms. Some pesticides are also toxic to humans.
