The Effects of Mineral Dissolution on Water Quality | Acid-base reactions and the concept of pH are critical concepts in chemistry, environmental sciences and Earth science. First, students will present hypotheses of whether the pH will increase or decrease when calcite or pyrite are dissolved in water. Second, in a facilitated activity, students (in groups) will dissolve pyrite and calcite in water and measure the pH after the minerals dissolve. Third, they will hypothesize what happens to the pH when they mix the pyrite and calcite together (in water). Fourth, they will then test their hypotheses by mixing them and measuring pH. Fifth they will discuss if their results support their hypotheses. Last, they will expand what they learned in the experiments to how minerals can be used in water treatment. |

Greywater Reuse | Greywater is any household wastewater other than that used for toilet flushing.
This water could be reused around the home (for purposes other than drinking
water). An example of greywater use is landscape irrigation. Wastewater that
comes in contact with human waste is referred to as blackwater. However, the
definition of greywater varies according to state regulations. |

Using Reclaimed Water | Reclaimed water, sometimes referred to as “water reuse” or “recycled water,” is
water recovered from domestic, municipal, or industrial wastewater treatment
plants that has been treated to standards that allow it to be safely used for
designated purposes. Reclaimed water should not be confused with “wastewater,”
untreated liquid industrial waste or domestic sewage. However, “gray water,”
untreated water from bathing or washing, is considered one form of wastewater
(Water Reuse, VCE Publication 452-014).
The level of treatment and disinfection reclaimed water receives is dictated by its intended (and permitted) use. Many states encourage and promote the use of reclaimed water to conserve freshwater supplies and preserve rivers, streams, lakes, and aquifers.

Rainwater Harvesting Systems | Rainwater harvesting is the process of collecting, storing, and later reusing rainwater
from surfaces such as roofs. Rainwater harvesting has long been used for agricultural
irrigation and as a source of drinking water, and allowed ancient civilizations to flourish
in semi-arid and arid regions. Rainwater harvesting systems are in use today in many
water-limited locations, especially in several western US regions. As population growth
increases pressure on water resources in the more humid eastern US, rainwater harvesting is
being considered to reduce the demand for potable water. |

What to Know When Buying a Home with Well and Septic | Apr 23, 2021 | BSE-340NP | |||
Spray Water Quality and Pesticide Characteristics | Pesticide sprays consist of at least 95% water. Water quality plays an important role in pesticide performance. The following issues may indicate a compatibility problem with pesticides and spray water quality:
- Pesticide does not work at labeled rates;
- Difficulty mixing sprays or clogging of nozzles;
- Inconsistent pest control observed in fields or plots;
- Pests seem resistant to a new pesticide active ingredient, or
- Crops are lower quality or lower yielding.
Understanding how water quality characteristics such as pH, water hardness, turbidity, and total suspended solids affect the adsorption and persistence (half-life, storage time) of a pesticide can help pesticide applicators reduce or eliminate compatibility issues and improve pesticide effectiveness |

Understanding Spray Tank Mixing Practices | Mixing two or more pesticide products can allow for the treatment of several pests at the same time, improve pesticide performance, and ultimately saving time and money. However, physical and chemical tank mix incompatibilities can occur when combining two or more pesticides. Physical incompatibility is the failure of pesticide products to stay uniformly mixed and can result in layering, products settling out of solution, or clumping. A chemical incompatibility is the result of a chemical reaction between pesticide products. A chemical incompatibility is less visible and can be harder to detect. This publication focuses on basic factors that influence product compatibility (agitation speed and method, water temperature, mixing order, carrier type, and chemical formulations) and summarizes best mixing practices to address these factors. |

Solving Spray Water Problems | Spray water problems may arise due to water quality and management decisions. Certain aspects of water quality can reduce the efficacy of the pesticide as well as affect how the pesticide interacts with the plant surface or targets pests. Evaluating and testing spray water chemistry can help identify water quality problems that might otherwise be overlooked. This publication will examine possible solutions to spray water problems, including the use of adjuvants and other additives to enhance pesticide performance. |
