rivers or lakes. Waste disposal pipes can be another example. Non-point source: Release of potential pollutants from a range of activities without a single or definite source. Agricultural facilities can be considered as non-point sources. Stormwater runoff, especially during heavy rainfall, in agricultural land/farmland may contain harmful substances such as pathogens and nutrients, and then enters waterways. Also, sedimentation is one of the main form of non-point source pollutions.…

The water quality of the UHS creek was found to have excellent water quality. There are other creeks, however, that have poor water quality. One way humans negatively affect water quality is by fertilizers and pesticide runoff, mainly used by farmers. Fertilizers and pesticides that drain into a river increases the amount of nitrate and phosphate considerably. This leads to a massive amount of algae growth, known as eutrophication. When the algae die, they are broken down by the bacteria which…

Foundation Repair Fredericksburg No one wants to hear you need you have a foundation problem. Foundations will settle over time and with gradual settlement you are less likely see real foundation issues. When you notice cracks in your foundation there is generally an underlying issue that needs to be evaluated by an experienced foundation repair company. Your homes foundation is the structure that supports your home and is in direct contact with the ground. The foundations job is to transfer the…

Pollution is a substance of anything that is harmful for the environment. Examples: acid rain, road salt, oil, and etc. We continue to use fossil fuels, road salt and fertilizer even though it would cause damage to ponds, lakes and other aquatic ecosystems is because human population needs to the kind of materials for needs for our industries and our environment in order to survive.The normal uncontaminated rain should be 5.0, in nature the pH range for acid rain is 6.5-8.5,however some other…

"Stormwater a sloppy slope" by: Ethan Crowe When you think of rain you think of a saving grace from the harsh heat of summer, or you might think of a fun time to play around outside. Sadly that time might come to an end. Storm water in the past might have been safe and slightly clean in the past but nowadays it causes many problems in our society. This paper will explain how and why it harms this society and how to prevent it. One of the main reasons storm water is harmful is the air…

My work revolved around the hydrological analysis of the city of Santa Cruz, California area in the San Lorenzo Watershed. My purpose was to determine if any relationship could be discovered between the rainfall and runoff data of the watershed area with the urbanization of the city. The problem at hand was to cross reference the development of Santa Cruz with the patterns of the local water data. Real precipitation and stream flow data within the San Lorenzo Watershed where studied from January…

carwash, but there are also some downsides. The water mixed with the soap will go straight to the sewer and into a lake.to prevent this runoff, using a commercial car wash will be a huge help. The wash will usually have a drain that doesn’t lead to a body of water. Another way is to wash cars on dry grass or gravel or some other permeable area to prevent runoff altogether. This is probably one of the safest tactics available in this situation. Factories are a huge contribution to the storm…

allowed new programs to be created to try and help combat acid rain. More recently, DC has implemented to the Clean River Project. In 2012, Maryland passed a law to help protect their local streams, rivers, and waterways by curbing runoff thereby reducing the level of runoff that reach the river, according to the website potomac.org*. This law made is possible for Maryland to collect a fee, based on the amount of paved or hardened surfaces on a property that collects pollution, from the…

According to King County Stormwater Services (2015), stormwater runoff accounts for approximately 1/3 of the water pollution in the Puget Sound. Contaminates like oil, pesticides, soaps, and industrial waste wash in to our local watershed where they negatively impact the local fish population and affect the supporting industry (Narayanan, 2013). Because of the unnatural rate and volume of stormwater flows it can damage wetlands and cause local flooding (Howard, 2007). The Pacific Northwest…

Steps I would take to evaluate the land conditions is to analyze and determine the main causes of the issue at hand by determining the causes of the degrading over overgrazing and invasive weeds that are replacing native grasses. By doing this we can analyze the causes of grazing by ranchers and study how restoring these lands through the restoration process that can be used in order to provide a positive effects and outlook on the environment. Some approaches we can take when evaluating…
