This project investigated using native Rio Grande cottonwood trees and zeolite to improve water quality in nearby urban streams and drains. Six test plots were established, with cottonwood trees planted in soil with or without added zeolite. Data on soil properties, plant health, weather, and water quality was collected. Initial results found the cottonwoods survived well and established baseline data on soil and plant conditions prior to irrigation testing.

Suitability Assessment of Shallow Groundwater of a Typical Coastal Aquifers f...iosrjce
Shallow Groundwater of a coastal aquifer has been intensively used as a source of water for
irrigation farming in the Niger Delta region of Nigeria. To assess the usability of this water for irrigation use,
twenty locations at buguma city were mapped out and five water wells were sampled for each location using
Simple random sampling technique. Each sample was analyzed for the cations(magnesium(Mg2+), sodium(Na+
),
potassium(K+
),calcium(Ca2+)),anion(nitrate ion(N03
-
)), trace elements(cadmium(Cd), iron(Fe), and zinc(Zn)and
other phsico-chemical parameters(Salinity(SI), electric conductivity(EC) and pH) adopting standard methods.
Based on the analyzed parameters, irrigation water quality parameters (RSC, SAR, %Na and %MR) and
indexes(Kelly index(KI), Permeability Index(PI) and the Canadian water quality index(CWQI)) were calculated
.To assess the usability of the shallow groundwater, results of the Water quality index models and other
calculated irrigation parameters were compared with the standards. On the average, virtually all the sampling
locations except Ombu, Igba and Jackreech were unsuitable for irrigation use.

Filtration of Greywater by Natural ProcessRohan Gajbhiye
This is my Under-graduation final year project presentation based on "Filtration of Grey water by Natural Process using Canna India Plant". My goal to to recycle Grey water for various day to day purpose of our life, so that, we can use and reuse the water for day to day needs such as Gardening, Farming, Car Washing and can prevent scarcity of water which also helps us to re-energize and replace the dry land with veggies and greneery .
Hope it helps. It's not just a presentation but it's a social message to all to help themselves by taking little steps everyday to save water and save life.
Stay healthy Stay fit.
1. ABSTRACT
The slow disappearance of riparian habitat which once flourished
throughout has been recognized to negatively impact surface water
quality. Restoring riparian habitat can lead to improvements in water
quality. This project investigated the ability of native riparian vegetation
specifically, Rio Grande Cottonwood (Populus fremontii), and zeolite to
improve water quality in nearby streams and drains. It was
hypothesized that the use of low water consuming established native
riparian vegetation along with zeolite mixed into the soil, will improve
water in nearby urban drains through filtration and phytoremediation of
contaminants. Findings from this research project contribute to the field
of riparian zone restoration by quantifying the ability of native riparian
vegetation to improve water quality.

RESEARCH OBJECTIVES
Future steps include initiating irrigation test, collecting and testing
leachate samples. As the irrigation testing continues further monitoring
and analysis of the soil and plants within each plots will be conducted.
including water quality, plant health, and nutrients will continue to be
monitored as the project progresses.

• Grow native riparian cottonwood trees and study their ability to
improve water quality along urban rivers and streams.
• Grow the cottonwood trees in two soil treatments: in-situ riparian sandy
soil and in-situ riparian sandy soil amended with a layer of clinoptilolite
zeolite.
• Collect soil samples to determine the soil type, sodium adsorption ratio,
and other soil chemical properties in each test plot
• Install drainage pipes to collect leachate samples from irrigation test
• Measure depth to groundwater
• Conduct health assessment of cottonwood trees in the experimental
plots on a weekly basis to determine growth and survivability
• Measure water quality of irrigation and the leachate in the drainage
pipes
Cottonwood Test Plot Configuration
1) Maintenance on the cottonwood test plots was conducted. Maintenance
involved removing weeds within plots and constructing fences around
the plants to protect them from beavers.
2) Conducted weekly plant health assessments during which qualitative
and quantitative data was collected for each plant in every plot.
3) Surface soil samples were collected from every plot for the summer
season to be tested to determine its chemical and hydraulic properties.
4) Leachate collection pipes were installed roughly 8 to 10 inches below
the soil surface in each plot. Care was taken to ensure that the pipes
would not collect ground water.
The data collected served as baseline data for conditions of the soil
and plants within the test plots prior to the irrigation test.
A sieve analysis of the soil type in each plot classified the soil as sand.
This information was used to help design the drainage pipes for
leachate collection and which test to perform on the soil to identify its
hydraulic properties.
Data from plant assessments showed 100% survival rate of
cottonwoods in all plots. Damage caused by beavers resulted in a
negative average overall change in plant height for plots 3 through 5.
Despite this, the average total growth of cottonwoods per plot were
similar.
The cation exchange capacity (CEC) of soil saturated paste (soil:
distilled water slurry of 1:1) ranged from 10.4 to 14.8 cmol/kg which is
typical for sandy and silt loam soils. The sodium adsorption ratio (SAR)
for the plots ranged from 3.19 to 8.68. The sodium adsorption ratio
(SAR) for the plots were below 13. At a SAR of 13 or above plants can
be negatively affected.
5) A weather station was installed onsite. The weather station has sensor
s to record the amount of precipitation, solar radiation, humidity, wind
speed and direction, and temperature.
6) Soil samples were tested to determine the particle size distribution, pH,
nutrients, salinity, conductivity, cation exchange capacity (CEC),
organic matter content, and sodium adsorption ratio (SAR).
7) Leaf samples were taken from plants in each plot and sent to Harris
AgSource Lab to have the nutrient content determined.
8) Depth to groundwater was measured at 4 wells throughout the site on a
weekly basis throughout the months of June and July.

RECOMMENDATIONS
• 6 cottonwood test plots, with 9 cottonwoods each
