As this organic matter decomposes, it uses up the oxygen intended for aquatic life survival. Decomposing organic matter also creates foul odors and taste in drinking water. Sweep leaf litter and collect in bags. Recycle matter for compost More frequent street sweeping Excessive irrigation Transports fertilizers, pesticides, dirt and grime to local storm sewer or waterway. Fertilizers and pesticides can kill aquatic life.
Oil can contaminate drinking water.
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.
