Cleaning up the Harbor and its tributary streams may seem like a massive task (and it is), but many seemingly small actions can collectively make a difference! 

To help residents, businesses, and other poperty owners understand the impact their land and buildings have on water quality and what they can do about it, Blue Water Baltimore has created the Water Audit Program

This completely free program includes a consultation with one of Blue Water Baltimore's stormwater experts and qualify you for a number of free and discounted services to help you implement the most appropirate runoff reduction strategies fo ryour property.

Things EVERYONE can do contribute to clean water

  1. Prevent it – Litter, pet waste, and excess fertilizers end up in our waterways are large storms.  If we limit the trash and the pollution flowing from our yards and streets, we will help allow for a healthier Harbor downstream by lowering the amount of pollutants that end up in our streams.
  2. Slow it – Studies have shown that slowing the movement of stormwater and keeping it onsite, rather than sending it directly into storm drains, which empty into our streams, can reduce stream erosion, sedimentation, and other processes that can further pollute the Harbor. Let’s get back to what nature intended before our communities were taken over with pavement - find ways to let the rain water soak into the ground instead of running onto the pavement and down the storm drains carrying pollutants into your neighborhood streams and the Harbor.
  3. Filter it – If stormwater is kept onsite and then used for practices like watering our gardens the plants and the soils they live in can act as filters, actually cleansing the water before it reaches our streams and rivers, which eventually empty into the Harbor.
  4. Plant it – Along with providing filtration, the plants in our yards, parking islands, and even in our alleys can provide shady spaces for community gatherings and recreation.  They also provide new habitat areas for birds and butterflies.  Studies have shown many benefits associated with increased numbers of urban trees including increased public healthy, improved property values, community pride and investment.
