Would you suggest any changes in the sampling strategy to better understand the waterways situation in the Preserve?</h2></span></font><br>

| − | <b> 1. Presence of Methylsomine – Area of Concern: </b>
| |
| − | Even though the soil samples taken from the preserve dint show any evidence of presence of Methylosmolene (the toxic manufacturing chemical in the suspected dumping) as the new soil has been tucked in, the water samples provides evidence for the justification of the presence of toxic in the preserve that might have negative effects in the wildlife and Blue Pipit birds.

| |
| − | As shown in the above picture, the methylosmoline has been with low values over the period of 2014 and 2015 in all locations, they have started showing increase in values from reading 15 mg/L to 45 mg/L in the Kohsoom region and from reading 4.5 mg/L to 130.5 mg/L in Somchair in the early January 2016. Apart from the increase , the Kohsoom region also shows the peak of Methylosmoline going up to 145 mg/L on August 26,2016. This may be due to the pollutants from the factory being high in this period , this region being the area close to the dumping region there is high probability for the chemical to be the root cause. This is an area of concern for the Blue Pipit Birds around the locations Kohsoom and Somchair. <br><br>

| − | The chemical recordings for this chemical is available only for the yeas 2014 – 2016 and the data is missing for the previous years. Apart from that, looking at above graph, the data is not consistently available for 2014 and 2016 all days, the readings are missing for the months November and December in Somchair in 2016. If the sampling is done better with conisistent readings across the locations for consiisten period of time, the hydrology department can justify the presence of Methylsolmoline in the preserve that harms the wildlife.

| − | <b> 2. Increasing Chemical Presence but lacks data to prove: </b>
| |
| − |
| |
| − | There are few chemicals like ammonium, arsenic and cyanides whose values has been showing different pattern in few locations in the preserve. Ammonium has been showing increasing trend in the readings captured by the hydrology department in recent years in the Kohsoom and Tansanee regions. The readings has been less than 2 mg/l throughout the years the samples were recorded, but the resding has jumped upto 7.39 mg/L in Kohsoom and 14.87 mg/L in Tansanee in the year 2014.<br>
| |
| − |
| |
| − | Cyanides have been below the average reading value throughout the years for all locations, but in decha region alone they have been increasingly higher compared to other regions with readings around 3 mg/L. The arsenic values in tansanee has been a unique distinctive in the pattern observed with the recent readings, they have a high value of about 17.14 above the average reading observed over the years. <br>

| |
| − |
| |
| − | <br><br>As all the chemicals shown above are toxic and contaminates the water with its presence, the birds over the surface water will also be affected. But as there is not consistent data records to prove the increasing trend, the sampling of data across regions serves a necessary action by the hydrology department.

| |
| − | <b> 3. Water Temperature Matters </b>
| |
| − |
| |
| − | The water temperature even though shows a cyclic trend across the locations with the peak reading being in the months of July and August, the region Tansanee has the highest water temperature among all the regions. This relates to the fact that the dissolved oxygen might be lower comparatively in this region as they are inversely related. But the lower dissolved oxygen will be harmful for aquatic life , but it might be advantageous for birds as the algae and debris become abundant in the preserve region creating food intake for the birds. The reason for the other regions having higher dissolved oxygen might be a concern for birds as the food sources in the rivers and streams are reduced.
